C# and Java are two very popular programming languages, each regularly topping the charts of the top 5 most widely use programming languages in the world. Both programming languages share a similar syntax and structure, and are often considered to be part of the same family of programming languages – notably, the “C-family”, which includes C, C++, and Java. Differences do exist between the two, however, and in programming tutorial, we will discuss the key differences between C# and Java, such as their syntax, performance, and memory management. Code examples will also be provided to better illustrate the differences in variable declaration, class creation, the use of pointers, string manipulation, and exception handling.

Differences Between C# and Java

Below are some key differences developers will find when choosing between working with C# and Java for their software development, including:

• Language type
• Syntax
• String Manipulation
• Exception and Error handling
• Performance
• Memory management and resource allocation

Language Type

One of the most important differences between C# and Java has to do with the type of language they are or their paradigm. Java is largely considered an object-oriented language programming language, which means it focuses on structuring programs through the use of objects and classes. In reality, however, Java is not a true OOP language, but, rather, has features of object oriented programming, such as inheritance, polymorphism, the use of classes and objects, and encapsulation. The use of primitive data types versus data types that are strictly objects, disqualifies it from being 100% object oriented.

Meanwhile, C#, is built on several development paradigms, including object-oriented, functional, and imperative programming.

A brief note: object-oriented programming (OOP) is based on the concept of objects, which contain data and the code required to manipulate that data. In Java, objects are created using classes, which can be thought of as “blueprints” that help define the attributes and methods that an object can possess. C# uses classes as well in order to create objects, but it supports functional programming concepts like lambda expressions and anonymous methods as well.

Syntactical Differences

C# and Java have several important syntactical differences as well, which can significantly impact how the languages are used. One of the main differences in their syntax has to do with the way Java and C# handle variable declaration.

In Java, variables are declared using the following syntax:

   = ;

Here is some sample code showing how to create and declare a variable in Java:

 int x = 10;
String name = "Nick";

Meanwhile, in C#, variables are declared using the following syntax:

   = ;

Here is some sample code showing how to create and declare a variable in C# – can you spot the difference?

 int x = 10;
 string name = "Nick";

You may have noticed that C# uses the keyword string instead of String, which is used by Java. A small, but notable difference.

Another difference between C# and Java with regards to data types is how pointers are handled. Java, for its part, does not have pointers, whereas C# does.

In C#, you can declare a pointer using the “*” symbol, as shown in the example code below:

 int* pointer;

The above C# code declares a pointer with an integer (or int) variable. The pointer can be assigned a memory address, which marks it for later use when a programmer needs to manipulate or reference the value stored in that specific memory address.

Class Differences in C# and Java

Both C# and Java rely on classes are to define objects. However, the way each declares a class differs. In Java, classes are declared with the class keyword, as shown in the following code example:

 public class ComicBook {
 	private String title;
 	private int issue;
	public ComicBook(String title, int issue) {
     	this.title = title;
     	this.issue = issue;
 	}
	public String getTitle() {
     	return title;
 	}
	public int getIssue() {
     	return issue;
 	}
 }

The code above defines a ComicBook class with two private fields: title and issue. The class additionally includes a constructor that takes two parameters – title and issue and two methods: getTitle() and getIssue().

In C#, classes are also declared using the class keyword, as shown here:

public class ComicBook {
 	private string title;
 	private int issue;
	public ComicBook(string title, int issue) {
     	this.title = title;
     	this.issue = issue;
 	}
	public string GetTitle() {
     	return title;
 	}
	public int GetIssue() {
     	return issue;
 	}
 }

You may have noticed that the syntax for declaring classes is almost identical between C# and Java. However, C# uses lowercase for method names while Java makes use of camel case.

Another difference involves how access modifiers are used. In Java, access modifiers such as public, private, and protected control the visibility of a class, method, or field, as well as define how they can be accessed. In C#, access modifiers are also used, but they are preceded by the accessibility keyword. Observe the code below:

public class ComicBook {
 	private string title;
 	private int issue;
	public ComicBook(string title, int issue) {
     	this.title = title;
     	this.issue = issue;
 	}
	internal string GetTitle() {
     	return title;
 	}
	internal int GetIssue() {
     	return issue;
 	}
 }

Here, the internal keyword is used versus public</b, making the methods visible only within the same assembly.

You can learn more about C# access modifiers in our tutorial: C# Access Modifiers.

String Manipulation in Java and C#

Manipulating strings is a common task in all programming languages, and C# and Java are no exceptions. Both languages provide similar functionality when it comes to working with strings, but each uses different syntax to achieve the same results. For instance, In Java, strings are objects that can be created using the String class. Here is some example code showing how to create a string in Java using the String class:

String name = "Nick";
int length = name.length();

In this Java code, the length() method gets the length of the string. In C#, strings are also objects, but they get created using the string keyword instead, as shown in this code snippet:

 string name = "Nick";
 int length = name.Length;

Notice, too, that the length() method is replaced with the Length property in C#.

Exception Handling Differences in C# and Java

Both C# and Java have mechanisms and features to help developers handle exceptions. Java, for its part, uses try-catch blocks for exception handling. Here is an example of how to handle exception with try-catch blocks in Java:

 try {
 	// code that yields an exception error
 } catch (Exception e) {
 	// code to retrieve and process the exception
 }

Meanwhile, in C#, exceptions, too, are handled using the try-catch block method, as shown here:

 try {
 	// code that yields an exception error
 } catch (Exception e) {
 	// code to retrieve and process the exception
 }

Application Performance

Application performance is also important when choosing a programming language. C# and Java are both compiled languages, meaning their code is converted into machine code prior to execution. That being said, there are differences in how each language is optimized, which, in turn, impacts performance.

Typically, developers consider C# to be faster than Java. This is especially true when it comes to memory management. C# makes use of a garbage collector to manage memory, which makes memory management more efficient. Java uses its own form of garbage collection via the Java Virtual Machine (JVM) and Just-in-Time compilation (JIT) which optimizes code for use on specific platforms.

You can learn more about JIT and the JVM in our tutorial: What is the Java Virtual Machine?

Memory Management

As discussed above, memory management is another important factor when deciding between C# and Java, who both rely on garbage collectors to manage memory. This reliance makes it so developers do not need to worry about manually allocating and deallocating memory resources. There are differences to note, mind you, in how C# and Java garbage collectors work, which can impact memory usage.

As stated, C# is generally considered more efficient in terms of memory management compared to Java. This is because C# uses a generational garbage collector, meaning objects that have been recently created are more likely to be collected than objects that have not. This leads to more efficient use of memory resources when compared to Java, which uses a mark-and-sweep approach to garbage collection when clearing temporary data that is no longer required.

Which is Better: C# or Java?

When choosing between C# and Java, your decision will ultimately depend on the needs and requirements of the software project and the personal preferences of the developer. C# is a great choice for Windows-based applications and if you want to code in the ,NET framework, especially if your application will require high performance and efficient memory management. Java, for its part, is a great choice for cross-platform development applications that can run regardless of system architecture or hardware and is great for web-based applications.

Final Thoughts on C# versus Java

In this programming tutorial, we look at two popular programming language options: C# and Java. We learned that both languages are object-oriented (or have object oriented features) and share similar syntax. There are differences in their paradigms, syntax, performance, and memory management, however, which sets them apart. C# and Java both have their strengths and weaknesses, and choosing the right one is largely based on project needs. Understanding their differences can help developers and programmers choose the right language for their software development projects and help optimize their development process.

Without a doubt, C and C# are two of the most powerful and popular programming languages used for software development in the world. Both languages share certain similarities, as their names suggest; however, they are also very different in terms of structure, syntax, performance, and, perhaps most notably, memory management. In addition, C and C# differ in terms of why a developer or programmer would choose to work with one over the other. This programming tutorial will compare C and C#, discuss their differences, and highlight each language’s strengths and weaknesses.

What are the Differences Between C# and C?

Below, we will discuss some of the differences between C# and C, which include:

• Procedural versus Object Oriented Programming
• Syntax
• Manipulating Strings
• Exception Handling
• Performance and efficiency
• Memory Management

Procedural versus Object Oriented Programming

C, at its core, is a procedural programming language, which refers to its step-by-step, “top down” method of programming. C uses functions – or procedures – that get called in a particular sequence in order to achieve an outcome. This top-down programming approach breaks down a problem, issue, or task into smaller tasks, which are then “solved” by working from the main problem down into its smaller problems.

C#, meanwhile, is an object-oriented programming (OOP) language. This means that C# is based on the concept of objects and classes and a parent-child-inheritance principle. Objects are made of both data and behavior, and are used to represent real-world things. These objects are created from classes, which can be thought of as the blueprints for objects.

Classes, for their part, are self-contained pieces of code that consist of the properties and methods of the objects that are created from them. Finally, in C#, developers use the principles of OOP, such as encapsulation, inheritance, and polymorphism to make code more secure, reusable, readable, and maintainable.

You can learn more about object-oriented programming concepts in the following tutorials:

• C# Object Oriented Programming for Beginners
• Introduction to Classes in C#
• C# Objects: A Deep Dive

C’s top-down programming approach is great for problem-solving smaller projects or tasks that can easily be broken down into easy, discrete steps. One good question to ask yourself when considering this type of programming methodology is whether or not the problem can be solved in a sequential or step-by-step manner.

C#’s OOP approach is better suited for larger projects that involve complex relationships and behaviors between objects and in situations where coding efficiency, security, flexibility, modulation, and reusability are more important.

Syntax Differences Between C and C#

One of the biggest differences between C# and C has to do with their syntax. C’s syntax focuses on low-level programming constructs, while C#’s syntax places a greater emphasis on object-oriented concepts and principles.

One example of the differences between C# and C’s syntax has to do with variable declaration. In C, developers declare variables with the data type placed before the name of the variable. Here is an example of variable declaration in C:

int num;
float price;

In C#, variables are declared with the var keyword, which infers the data type. This is then followed by the variable name. Here is how programmers can declare a variable in C#:

var num = 0;
float price = 0.0f;

Another syntactical difference between C# and C is the fact that C allows for low-level memory management via the use of pointers. The following code example shows how to declare a pointer in C using the * operator:

int* ptr;

C# does not allow developers to explicitly use pointers; to achieve the same type of functionality would require a C# programmer to use unsafe code, which is beyond the scope of this tutorial.

As noted previously, C# is an object oriented language. C, meanwhile, is not, and therefore does not have built-in support for classes or other OOP concepts. C coders can, ultimately, mimic class functionality, but it requires complex structures to achieve what C# does naturally and with much less effort.

Since C# is an object-oriented programming language, classes in C# can be declared with the class keyword, as shown in the code example below:

public class MyClass
{
    // class members and methods
}

Manipulating Strings in C# and C

The way string data types are manipulated in C# and C is also a key difference between the two languages. In C, strings are represented as an array of characters and are null-terminated using the\0 character. Here is an example of this in C:

char str[] = "Hello, World!!";

In C#, strings are objects that are manipulated using the methods and properties of the String class. The C# code below achieves the same thing as the C code in our previous example:

string str = "Hello, World!";

Exception Handling

Exception handling and error handling differs between C# and C as well. In the C programming language, errors are typically handled using return codes giving information about the error or by terminating the program altogether.

Handling errors is different in C#, where programmers use exceptions to handle errors, which can be “caught” using try-catch blocks, as shown in this example code:

Try
{
    // code that might return an exception error
}
catch(Exception ex)
{
    //code that handles the exception
}

Performance and Efficiency

C is well-known for being a high performance programming. This is due to its low-level programming constructs and direct access to memory. C#, on the other hand, is a higher-level language, meaning that, in some instances, it can be slower than C. This difference has mostly been mitigated in recent years, thanks to introduction of the .NET Core runtime and other C# language optimizations. Presently, C# is now considered comparable to C in terms of overall performance.

Memory Management in C# and C

Lastly, C, being a low-level programming language, gives developers direct access and control over memory management. This equates to greater efficiency and performance in created software; it also means that programmers need to be cautious to avoid memory leaks.

C#, as a higher-level language, includes automatic memory management courtesy of the .NET runtime, which manages memory allocation and deallocation for the developer. This comes at a slight cost to performance, as garbage collection can be resource intensive in some instances/ However, this is mostly negligible and well-worth the trade off for many developers who do not wish to be burdened with memory management.

Which is Better: C# or C?

Deciding which language is better – C# or C – is a complicated process that largely depends on the needs of the developer and the project at hand, as well as which career path the programmer will pursue.

C is often chosen for developers wanting to program systems or pursue embedded development (such as the IoT and smart devices), as it provides low-level access to hardware and the direct manipulation of memory resources. Developers creating an operating system, device driver, or system-level software, would be wise to choose C as their primary programming language.

If you are into video game programming or game development, C# is a better option, as it provides a high-level, object-oriented approach that is more tailored for the complexities of game logic and working with graphics. C# game developers will also be supported by game development tools and game engines like Unity, which is built on C#. Game engines and mobile developer low-code platforms provide powerful, pre-built tools for game development, and C# is streamlined for creating complex game logic routines.

For Enterprise-level software, C# gains the edge, because its reliance on OOP provides an object-oriented approach that makes it easier to work with larger, more complex applications. Developers that want to create a scalable enterprise application will want to choose C# because of its scalability, ease of use, easier learning curve, readability, ability to integrate with databases, and the option to incorporate frameworks such as .NET. Finally, C# provides flexibility and can be used to create complex business logic processes and user interfaces.

Final Thoughts on C# versus C

In this programming tutorial, we discuss both C and C# and the differences between the two programming languages, including their syntax, performance, string manipulation, and memory management. We learned that C is a low-level language that gives developers direct control over memory management and memory resources, while C# is a higher-level language with object-oriented features and automatic memory management and garbage collection.

In this programming tutorial, we will look at the different types of compilation offered in .NET, C#, and ASP.NET.

Read: Top Online Courses to Learn .NET Software Development

What are the Types of Compilation in .NET?

The process of compilation in .NET is performed in two ways: implicitly and explicitly:

• • Explicit compilation: An explicit compiler compiles the source code into machine code prior to the execution of the program. Ahead of Time (AOT) compilers are used to perform explicit compilation so that each line of the code is understood by the CPU before the execution of the program.
  • Implicit compilation: Implicit compilation takes place in two steps. First, the source code is converted into intermediate code (such as MSIL or Microsoft Intermediate Language Code) by the language-specific compiler. In the second step, this intermediate language code is converted into machine code. The difference from an explicit compiler is that, at runtime, only the executed fragment of intermediate language code is compiled into machine code. This type of compilation in .NET is called Just-in-Time (JIT) compilation.

What is JIT Compilation?

JIT is a part of the CLR (Common Language Runtime) in .NET, which is used to execute a .NET program, regardless of which .NET-supported programming language is used.

The program execution in .NET is performed using the following steps:

• A language-specific compiler converts the programming language code into the intermediate language
• The intermediate language code gets converted into machine code by the JIT compiler.
• The machine code generated is specific to the computer platform.

You can learn more about the CLR on Microsoft Learn.

How Does the JIT Compiler Work in .NET?

The JIT compiler converts the intermediate language (IL) or MSIL code into machine code. The MSIL code is then converted as per the requirements of the program only and not the whole of it. .NET also keeps the MSIL code stored so it can access the source code methods on subsequent calls.

Types of JIT Compilers in .NET

.NET has three types of JIT compilers. They are:

• Pre-JIT compiler
• Normal JIT compiler
• Econo JIT compiler

We discuss each type of .NET JIT compiler in the following section.

What is a Pre-JIT Compiler

The Pre-JIT compiler compiles the source code into machine code in a single compilation cycle. Usually, this type of compilation is performed at the time of application deployment. This is implemented in Ngen.exe (Native Image Generator). The following figure shows the typical function of the Pre-JIT compiler:

What is a Normal JIT Compiler

In normal JIT compilation, source code is converted into machine code only the first time it is called by the runtime. After that, it is stored in cache and can be accessed whenever required.

What is an Econo JIT Compiler

An Econo JIT compiler compilation method only compiles the functions which are needed at the runtime and removes them once they are no longer required. The Econo JIT compiler became obsolete with the advent of .NET 2.0, but we include it here for awareness and historical purposes.

What are the Advantages and Disadvantages of JIT Compilation in .NET

JIT compilation has the following advantages for .NET developers:

• JIT performs code optimization by performing statistical analysis.
• JIT compilation consumes less memory, as only the functions which are required at the runtime are compiled into machine code.
• JIT compilation is less prone to errors because all the functions required at runtime are on the same memory page.

Along with these advantages, JIT compilation also has its disadvantages in .NET, which include:

• The JIT compiler takes more startup time when the program is executed for the first time.
• Cache memory, which is an expensive resource, is used heavily in JIT compilation to store the source code methods, since these methods are required at runtime.

Middleware is a piece of computer software that allows software ( such as an internet application) to communicate with databases, servers, and remote machines. Middleware handles the HTTP requests and HTTP responses between a client and a server, which helps developers build better and more efficient software architecture.

Read: Best Online Courses to Learn C#

In this programming tutorial, we discuss what middleware is, how it can be used, and look at some example of using ASP.NET Core middleware and C# to create web applications.

What is ASP.NET Middleware?

The ASP.NET Core middleware was introduced to lessen the dependency of .NET websites and applications on servers. Before the introduction of middleware, the request and response objects in .NET were tightly-coupled with web servers, which led to poor maintainability of code. Middleware, fortunately, mitigated this problem. In the next section, we will look at how middleware functions in a typical .NET website and leads to better code maintainability.

How does Middleware Work in .NET?

.NET Core middleware makes use of the request pipeline to handle HTTP requests. Developers can configure the request pipeline using different methods, such as run(), map(), and use.

The request pipeline decides whether an HTTP request should be passed to the next component in the pipeline for processing. Apart from that, the request pipeline also takes care of the required actions that need to be performed before – or after – the invocation of a component in the pipeline.

It should be noted that one application can make use of more than one middleware, depending upon the needs of the application. You can utilize the built-in middleware that comes with .NET Core or get them from the NuGet package manager. This is how the middleware functions.

Below are some of the different built-in middleware components available in .NET and their function:

• Session: Used for user session management.
• CORS: Used for Cross-origin Resource Sharing (CORS) constraint.
• Routing: Used for defining and managing routes
• Authentication: Used for authenticating users and roles

How to Set Up a Middleware Pipeline with ASP.NET

Now that we have a better grasp of what middleware is, how it functions, its role in the request pipeline, and its components, let’s preview a practical example of how to set up a middleware pipeline for your ASP.NET website.

To achieve this, web developers need to make use of the configure() method, which is defined in the Startup class, whose function is to add the components below to the website lifecycle. It is important to note here that you should take care while defining the order of middleware, otherwise your application might not perform well or become unresponsive:

• Model-View-Controller (MVC) with the area defined
• Error handling
• Session
• Cookie Policy

We can better understand the importance of middleware through the following code example. Inside the configure() method of the Startup.cs class, we have the following C# code:

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
app.UseBrowserLink();
}
else
{
app.UseExceptionHandler("/Home/NotFound");
}
app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseCookiePolicy();
app.UseSession();
app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "blog",
        pattern: "blog/{*article}",
        defaults: new { controller = "Blog", action = "Article" });
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "{controller=Books}/{action=Details}/{id?}");
});

Below is an outline of the workflow of the above code. In this example:

• The first middleware we used in our example is for error handling. In the development environment we used UseDeveloperExceptionPage and in the production environment we used UseExceptionHandler.
• Next in the pipeline, we have the UseHttpsRedirection middleware, which redirects the HTTP request to the secure HTTPS.
• Then, we used UseStaticFiles middleware. Its function is to serve the static files to the browser by adding them to the request pipeline. Usually, static files are stored in the webroot folder and developers can access them through that path. However, it is up to the programmer; you can also store files in any other directory.
• Next, we use the UseCookiePolicy that adds the CookiePolicyMiddleware handler to the specified request pipeline. It ensures the application should remain compliant with the General Data Protection Regulation (GDPR) standards, laws, and regulations.
• After this, the next middleware used is UseSession. Its purpose is to provide support for user session management. If you forget to place this middleware, then you will not be able to access the session data.
• Last up, we have UseMvc. This is the last middleware in our request pipeline. This should be placed at the end of the pipeline so that when it comes to action, all the authentication and session work gets completed.

Final Thoughts on Middleware and ASP.NET

Middleware is one of the beneficial features .NET provides for its developers. Middleware helps ASP.NET developers to develop their websites or web applications with more control over client-server communication. We can use various middleware depending on our project requirements or even create our own customized one.

An access modifier in C# is a keyword used to indicate whether a member of a class can be accessed from outside the class. By using access specifiers, developers can control how one part of the application’s code can interact with another part of the code, which helps in building more robust, modular and maintainable applications.

This programming tutorial will discuss access modifiers in C#, their benefits, and how they can be used in C#.

Before reading further, you may wish to check out a few of our other tutorials on object-oriented programming (OOP) concepts if you are new to the subject or need a refresher:

• C# Object Oriented Programming for Beginners
• Introduction to Classes in C#
• C# Objects: A Deep Dive

What is an Access Modifier in C#?

An access modifier is a keyword in C# that specifies the level of access to a class or its members. It is used to control visibility and accessibility of class elements in C#, allowing you to control who can and cannot access different parts of your code. It is important to choose the appropriate access modifier for each member based on its intended usage and the level of encapsulation desired.

These access specifiers are used to control the visibility and accessibility of members of a class or struct, which helps in maintaining encapsulation and ensuring the correct use of the program. By using access specifiers, developers can control how other parts of the program can interact with their code, which helps in building more robust and maintainable applications.

You can learn more about C# encapsulation in our tutorial: Overview of Encapsulation in C#.

What is the public Keyword in C#?

In C#, the public keyword is an access specifier used to declare a type, method, or member as accessible to all code in the program. Members marked as public can be accessed from any code that has access to an instance of the class or struct they belong to.

Here are some key points about the public keyword in C#:

• A class or struct that is marked as public can be accessed from any other code in the program, even if the code is in a different namespace or assembly.
• A method, field, property, or event marked as public can be accessed from any code that has access to an instance of the containing class or struct.
• The public keyword can be used in combination with other access specifiers, such as static or readonly, to create more specific access rules.

What is the private Keyword in C#?

In C#, the private keyword is an access specifier used to declare a type, method, or member as accessible only within the same class or struct. The private keyword helps to ensure the integrity of a class or struct by hiding implementation details and preventing unintended access and modification of private members from outside the containing class or struct. Members marked as private cannot be accessed from any other code outside the containing class or struct thus enforcing encapsulation and maintaining the security and integrity of your code.

Here are some key points about the private keyword in C#:

• Programmers can access a private method, field, property, or event from within the same class or struct only.
• A class or struct marked as private cannot be accessed from any other code in the program.
• The private keyword is the default access level if no access specifier is explicitly defined for a type, method, or member.

What is the protected Keyword in C#?

In C#, the protected keyword is an access specifier used to declare a member as accessible within the same class or struct, and any derived class. Members marked as protected cannot be accessed from any other code outside the containing class or struct or its derived classes.

Here are some key points about the protected keyword in C#:

• A protected method, field, property, or event can only be accessed from within the same class or struct, or from any derived class.
• A class or struct marked as protected cannot be accessed from any other code in the program.
• The protected keyword is often used to provide a mechanism for derived classes to access the internal workings of a base class, while still maintaining encapsulation.
• The protected keyword helps to ensure the integrity of a class or struct by allowing derived classes to inherit and extend the behavior of the base class, while preventing unintended access and modification of protected members from outside the containing class or struct or its derived classes.

What is the internal Keyword in C#?

In C#, the internal keyword is an access specifier used to declare a type, method, or member that can only be accessed inside the same assembly.

Here are some key points developers should know about the internal keyword in C#:

• A method, field, property, or event marked as internal can be accessed from any code within the same assembly.
• The internal keyword is often used to hide implementation details of a class or struct from other assemblies, while still allowing other types within the same assembly to access the members.
• The internal keyword is different from the private keyword in that private members cannot be accessed from any other code, whereas internal members can be accessed from any code within the same assembly only.
• The internal keyword is useful for creating reusable code components, as it allows you to define implementation details within a single assembly while still providing a public interface that can be accessed from other assemblies.

The protected internal Access Modifier in C#

The visibility and accessibility of a protected internal member is both protected and internal to the same assembly. It allows a member to be accessible within the same assembly and also by derived classes, whether they are in the same assembly or in a different assembly.

Here are some key points programmers should understand about the protected internal access modifier in C#:

• A method, field, property, or event marked as protected internal can be accessed from any code within the same assembly and by any derived class, whether they are in the same assembly or in a different assembly.
• The protected internal access modifier is useful for creating a flexible and extensible class hierarchy that can be used across different assemblies while still maintaining encapsulation and access control.
• The protected internal access modifier is often used in class libraries or APIs that are intended for use by multiple applications or services.

The private protected Access Modifier in C#

A private protected member combines the features of both private and protected access specifiers. It allows a member to be accessible within the same class or struct or any derived class within the same assembly, but not by any code outside the containing class or struct or its derived classes in other assemblies.

Here are some key points about the private protected access modifier in C#:

• A method, field, property, or event marked as private protected can be accessed from within the same class or struct, and any derived class within the same assembly.
• A class or struct marked as private protected can only be accessed from within the same assembly by the containing class or struct or any derived class.
• The private protected access modifier is useful for creating a class hierarchy with strict access control, where the implementation details of a class can be accessed by derived classes within the same assembly only.

Use Cases of Access Modifiers in C#

Here are some use cases of access modifiers in C#, which include encapsulation, access control, inheritance, modularity, and maintenance:

• Encapsulation: You can take advantage of access modifiers to hide implementation details and expose only the essential information to the outside world. This is important for creating classes that maintain the integrity of data and provide a clear interface for interacting with them.
• Access Control: Access modifiers allow developers to control which code can access certain types and their members. As a result, only code that is authorized can have access to the sensitive data in your application.
• Inheritance: Access modifiers play a key role in inheritance, allowing derived classes to access the protected and public members of their base class. This is essential for creating class hierarchies and facilitating code reuse.
• Modularity: Access modifiers enable developers to create modular code that can be reused in different contexts. By controlling the visibility and accessibility of types and members, developers can create components that can be used in different parts of an application or even in different applications.
• Maintenance: Access modifiers help make code more maintainable by making it clear which members are intended for internal use and which are part of the public interface. This helps developers avoid unintended changes to the implementation of a class or the behavior of an application.

Syntax for Access Modifiers in C#

Now that we know about the different types of access modifiers C# has to offer, let’s take a look at a quick code example that demonstrates the syntax for using C# modifiers:

public class Car
{
	public void Tire() { }
}

Here is example code showing how you would create a private access modifier in C#:

class Car
{
	private string model = “El Camino”;
	static void Main(string[] argos)
	{
	Car testObj = new Car();
	Console.WriteLine(testObj.model);
	}
}

In the above code example, we use a private access modifier to make our access level private and then create a new instance of Car, assigning it the model of El Camino, which we then print to the screen.

Final Thoughts on C# AccessModifiers

Access specifiers in C# are keywords used to determine the accessibility or visibility of a type, member or method in a class or struct. They play an important role in creating well-encapsulated, modular, and maintainable code that can be easily extended and reused in different contexts. By controlling the visibility and accessibility of types and their members, developers can ensure that their code is secure, efficient, and easy to maintain over time.

This programming tutorial discusses properties in C#, their benefits, and how they can be used in C#.

Before delving too deep into this article, we have a few articles discussing the basics of object-oriented software development if you need a refresher or are new to the concept:

What Are Properties in C#?

In C#, a property is a member of a class that can be used to read or write values from and to a field of the class. Properties are used to encapsulate the implementation details of a class and provide a controlled way to access its internal state.

It is a mechanism for exposing private fields of a class to the outside world while still controlling the access to them. A property provides a way to read and write the value of a private field by using get and set accessors.

Properties are used in C# for a variety of reasons, including to provide encapsulation, validate data, compute values, and to enforce constraints:

• Encapsulation: By encapsulating the state of an object behind a property, you can prevent direct access to the private fields of the object, which helps maintain the integrity of the object’s state.
• Data validation: Properties can be used to validate the data being set on an object. For example, you could use a property to ensure that a number is always positive, or that a string has a maximum length.
• Computed values: Properties can be used to compute a value on the fly based on the values of other properties or fields.
• Access control: Properties can be used to control access to an object’s state by limiting access to certain fields or properties.
• Properties can be used to enforce constraints, validate data, and provide a simple way to access data in an object.

You can learn more about encapsulation in our tutorial: Overview of Encapsulation in C#.

Types of Properties in C#

There are several types of properties in C#, including read-only, write-only, indexer, and virtual types:

• Read-only properties: These properties only have a get accessor, which means that their value cannot be changed once they are set.
• Write-only properties: These properties only have a set accessor, which means that their value can only be set, not read.
• Auto-implemented properties: These properties are shorthand for defining a private field and its associated get and set methods.
• Indexer properties: You can use these properties to access instances of a class using an index, much the same way you do with an array.
• Virtual properties: Virtual properties are defined in the base class and they can be overridden by the derived classes.
• Static properties: As the name suggests, static properties are not associated with the object of the class, instead they are associated with the class.
• Abstract properties: Abstract properties are declared in an abstract class or interface in C#. You must implement them in any non-abstract class that derives the abstract class or implements the interface.

How to Program Properties in C#

In C#, properties are defined using the get and set keywords. The get method is used to retrieve the value of the property, while the set method is used to set the value of the property.

The syntax for defining a property in C# is as follows:

access-modifier type PropertyName
{ 
   get 
   { 
        // Write your get accessor logic here
    } 
   set 
   { 
       // Write your set accessor logic here
   }
}

The following code example illustrates a property in C#:

public class MyClass
{
    private int myProperty;
    public int MyProperty
    {
        get { return myProperty; }
        set { myProperty = value; }
    }
}

In the preceding code example, MyProperty is a property of the MyClass class. It has a private backing field myProperty, which is accessed by the get and set accessors of the property. While a get accessor is used to retrieve the value of a data member of the class, and the set accessor sets a specified value to the data member.

Here is another code example in which the Person class has a property called Name.

Here is another example of a simple property in C#:

 
public class Person
{ 
  private string firstName, lastName, address;
  public string FirstName 
  { 
     get 
     { 
       return firstName; 
     } 
     set 
     {
       firstName = value; 
     } 
   }
public string LastName 
  { 
     get 
     { 
       return lastName; 
     } 
     set 
     {
       lastName = value; 
     } 
   }
public string Address 
  { 
     get 
     { 
       return address; 
     } 
     set 
     {
       address = value; 
     } 
   }
}

In this example, the Person class has three private fields, namely, firstName, lastName, and address.. You can access each of them using the corresponding public properties named FirstName, LastName, and Address.

Properties can also have different access modifiers, such as public, private, protected, or internal, just like other class members. They can also be read-only, write-only, or read-write, depending on whether or not they have a set method.

What is an Automatic Property in C#?

In C#, an automatic property is a shorthand syntax for defining a property that simplifies the syntax for declaring and initializing properties. Using automatic properties, programmers can declare a property without having to define a private field to store the property value explicitly.

Instead, the C# compiler automatically generates a private backing field for you, and you can access the property using get and set accessors. The basic syntax for an automatic property in C# is as follows:

public class MyClass
{ 
  public string MyProperty { get; set; }
}

In this code example, MyProperty is an automatic property. The get and set keywords define the accessors for the property, and the type of the property is string. When you create an instance of the MyClass class and set the value of the MyProperty property, the compiler automatically creates a private backing field to store the value. For example, you can create an instance of MyClass and set the value of MyProperty like this: var myObject = new MyClass();

myObject.MyProperty = "This is a sample text";

In this example, the value ” This is a sample text “ is stored in the private backing field created by the C# compiler for the MyProperty property.

Here is another example of an auto-implemented property in C#:

 
public class Author
{ 
   public int Id { get; set; }
   public string FirstName { get; set; }
   public string LastName { get; set; }
}

In this code example, the “Id”, “FirstName”, and “LastName” properties do not have an explicit field mapped to them, but the compiler generates one for each of them automatically.

Automatic properties can be useful for reducing boilerplate code in your C# classes, but keep in mind that they have some limitations. For example, you cannot add additional logic to the get and set accessors of an automatic property, such as validation or calculations. If you need to do more than simply get or set a property value, you will need to define a traditional property with an explicit private field.

Final Thoughts on C# Properties

Properties are a powerful feature of C# that allow for flexible data access and manipulation, while also enabling developers to enforce constraints and protect your data from being exposed directly. You can take advantage of properties to implement encapsulation, access control, and data validation in object-oriented programming.

Check out our tutorial: Class Members in C# for more information on OOP programming and working with classes.

Encapsulation is one of the striking features of object-oriented programming (OOP) that enables programmers to hide the internal details of an object while providing a well-defined interface for interacting with it.

This programming tutorial will discuss encapsulation, its benefits and how it can be implemented in C#.

Before reading further – if you are new to OOP software development in C#, or want to refresh your memory, we have a few tutorials we recommend checking out:

• C# Object Oriented Programming for Beginners
• Introduction to Classes in C#
• C# Objects: A Deep Dive

What is Encapsulation in C#?

Encapsulation refers to hiding an object’s internal implementation details from the outside world while exposing only the essential information. It allows developers to design classes with an interface for interacting with other code while protecting the internal data and implementation from external interference.

Encapsulation has several benefits, including improving code maintainability by making it easier to modify and extend without affecting other system parts. It also enhances the security and reliability of code by limiting external access to sensitive data and enforcing business rules and constraints.

Encapsulation in C# is achieved by taking advantage of the access modifiers that include public, private protected, private, internal, and protected that control their visibility and accessibility of the members of a class.

By making data members private and exposing them only through public methods or properties, encapsulation allows developers to prevent external code from directly manipulating the object’s data and ensures that any changes to the internal implementation can be made without affecting other parts of the system.

Since the members of a class are private by default in OOP languages such as Java and C#, you can only access them within the class. By using the public modifier, a member can be made accessible from outside the class. Encapsulation promotes data integrity and security and allows for easier maintenance and evolution of the codebase.

You can learn more about class members in our tutorial: Class Members in C#.

How to Implement Encapsulation Using Access Modifiers in C#

In this section we will take a look at some examples of encapsulation using access modifiers in C#.

Consider the following code example that shows a class containing public members:

public class Rectangle
{
    public double Width { get; set; }
    public double Height { get; set; }

    public Rectangle(double width, double height)
    {
        Width = width;
        Height = height;
    }
    public double Area()
    {
        return Width * Height;
    }
    public double Perimeter()
    {
        return 2 * (Width + Height);
    }
}

In this C# code example, the Rectangle class has two public members – Width and Height. These members are accessible from outside the class and can be read and written directly. The class provides the public methods Area() and Perimeter() to allow outside code to interact with the object.

Hence, in this class design, the data members of the class are not encapsulated from the external world.

The following is a code example that shows a class that contains private members in C#:

public class Account
{
    private string accountNumber;
    private decimal balance;
    public Account(string accountNumber, decimal balance)
    {
        this.accountNumber = accountNumber;
        this.balance = balance;
    }
    public decimal GetBalance()
    {
        return balance;
    }
    public void Deposit(decimal amount)
    {
        balance += amount;
    }
    public void Withdraw(decimal amount)
    {
        if (balance >= amount)
        {
            balance -= amount;
        }
    }
}

In this example, the Account class has two private members: accountNumber and balance. These members are not accessible from outside the class. The class provides public methods GetBalance(), Deposit(), and Withdraw() to allow outside code to interact with the object.

The following code example illustrates a class that comprises protected members:

public class Animal
{
    protected string name;
    protected int age;
    public Animal(string name, int age)
    {
        this.name = name;
        this.age = age;
    }
    public virtual void MakeSound()
    {
       Console.WriteLine("Inside the MakeSound method of Animal class…");
    }
}
public class Tiger : Animal
{
    public Tiger(string name, int age) : base(name, age)
    {
    }
    public override void MakeSound()
    {
      Console.WriteLine("Inside the MakeSound method of the Tiger class…");
    }
}

In this code example, the Animal class has two protected members: name and age. These members are accessible from derived classes like Tiger, but not from outside the class hierarchy. The Animal class provides a virtual method named MakeSound() that can be overridden by the derived classes, such as the Tiger class.

How to Implement Encapsulation Using Properties in C#

The code example given below shows a class with private data members exposed to the external world using corresponding public properties in C#:

public class Person
{
    private string name;
    private int age;
    public string Name
    {
        get { return name; }
        set { name = value; }
    }
    public int Age
    {
        get { return age; }
        set { age = value; }
    }
    public Person(string name, int age)
    {
        Name = name;
        Age = age;
    }
}

In this example, the Person class has two private fields: name and age, and two public properties – Name and Age. The properties provide encapsulation by allowing outside code to read and write the private fields indirectly, rather than accessing them directly. This allows the class to control access to the fields and enforce business rules if necessary.

The following code example shows a class that contains read-only properties in C#:

public class Circle
{
    private readonly double radius;
    public Circle(double radius)
    {
        this.radius = radius;
    }
    public double Radius
    {
        get { return radius; }
    }
    public double Area
    {
        get { return Math.PI * radius * radius; }
    }
}

In this example, the Circle class has a private field radius and two public read-only properties – Radius and Area. The read-only properties provide encapsulation by allowing outside code to read the private field but not modify it. This ensures that the Circle object remains immutable, makes your data secure and enforces encapsulation.

Use Cases and Benefits of Encapsulation in C#

Some of the common use cases and benefits of encapsulation include data integrity, increased security, reusable code, easier testing, and modularity, as well as the following:

• Security and data integrity: Encapsulation provides a layer of security and data integrity by preventing unauthorized access and modification of data. By making class members private and exposing them via only a well-defined interface, encapsulation ensures that the internal workings of an object are hidden from outside code. This helps to prevent bugs, errors, and security vulnerabilities caused by direct access to internal data.
• Abstraction and modularity: Encapsulation facilitates better abstraction and modularity in code. By encapsulating complex logic in well-defined objects, developers can abstract away implementation details and focus on high-level functionality. As a result of this, the code becomes easier to read and maintain over time, and it is also simpler to modify.
• Code reuse: Encapsulation promotes code reuse by making it easy to reuse objects in different parts of the codebase. By exposing a well-defined interface, objects can be used by other parts of the codebase without needing to know about their internal implementation.
• Testing: Encapsulation makes testing easier by allowing developers to test objects in isolation from the rest of the codebase. By encapsulating logic in well-defined objects with well-defined interfaces, developers can create isolated test cases for individual objects and test them independently.
• Flexibility and maintenance: Encapsulation can also improve code organization, flexibility and maintenance by providing a way to optimize internal implementation without affecting external code. By encapsulating implementation details, developers can change the internal implementation of an object without affecting other parts of the codebase.

Final Thoughts on C# Encapsulation

Encapsulation helps developers write more secure, maintainable, and extensible code. By carefully choosing which members to expose and which not to, encapsulation helps to ensure that the class remains maintainable, reusable, and extensible. When you need to alter the implementation of a class, you can often use encapsulation to make sure that you do not affect the clients of the class that depends on it for its functionality.

The coronavirus pandemic led to an explosion of work-from-home setups for developers, as many were forced to leave the office for the comfort of their couches. Even with the pandemic mostly in our rearview, however, remote work continues to be popular and appears as if it is here to stay.

While working remotely has its benefits – such as giving developers more freedom with their schedules – it can be a challenge, especially when it comes to productivity. That is why we will discuss several tips for remote developers to help you make the most of this increasingly popular work setup.

In addition, many developers collaborate with other programmers from different regions of the globe, so the tips inside this software development tutorial will be helpful in these scenarios as well.

Remote Developer Tips

Whether you just got a new job as a remote developer or have been working from home for a while now, here are some tips to help you boost productivity and achieve overall success while programming away from the office.

Create A Designated Workspace

One of the biggest challenges you will face as a remote developer, programmers, or software engineer, is separating your workspace from the rest of your home. To avoid blurring the lines between work and home, you should do your best to create a designated workspace that serves as your office and nothing else. This lets you replicate the feel of an employer’s office, makes you feel like you are actually at work, and makes it easier to leave your office (and the tasks associated with it) once the day is over.

You do not need a huge home to pull off this tip. Even if you live in a studio apartment, you could put a small desk in a corner and designate that as your workspace. Taking things even further, you could make a rule that you only use that small desk on Monday through Friday strictly for work purposes. By having that workspace, you can make it easier to concentrate on tasks and avoid one of the biggest obstacles of remote work: distractions.

Work A Consistent Schedule

Not having a designated workspace can blur the lines between work and home life, and so can not having a consistent schedule.

Even though one of the top work-from-home benefits is having more control over your time, some programmers may find themselves working extra hours since switching to a remote position. To avoid burnout, set a consistent schedule, so you know when work begins and ends. Sticking to a schedule can also increase focus and let you know that there are specific times when all your focus should be on coding, for example, and not errands.

Avoid open schedules, as they can lead to excess work, poor time management, less focus, poor work-life balance, and burnout.

Get A Second Phone Number

It can be hard to gain the ideal work-life balance if your team members or project manager are constantly calling your phone at all hours of the day and night. You can avoid this common remote work issue by getting a second phone line used strictly for work purposes. It does not have to be an actual second phone with a separate SIM card, either, as a simpler service like Skype or Google Voice could suffice.

Tell your colleagues this is the phone number they can call with any questions pertaining to work. Even better, give them an exact schedule of when they can call and expect you to answer the phone.

Take Breaks from Programming

Spending most of your work time on a computer does not shield you from the potential health problems of overworking. Sure, you may not be lifting heavy machinery in an oil field, but you can still set yourself up for future health issues if you overstress yourself and do not get the proper rest you need.

Many developers make the mistake of hunching over their desks for several hours at a time. This can lead to fatigue, plus eye, neck, back, and shoulder problems. Take advantage of your remote setup and schedule various short breaks throughout the day to avoid such potential health problems. Not only will you allow yourself to recharge your brain and body, but you will also boost productivity by ensuring you are not too tired to get the job done.

Keep In Touch With Team Members

Working remotely requires extra effort from developers in terms of communication and collaboration. By being at home, you are physically separated from others, which reduces human interaction and cuts down on communication that typically comes from being together in an office setting. As such, you will need to make a conscious effort to reach out to team members daily or at least every other day to keep everyone on the same page.

Use your team’s preferred communication avenue to post daily updates of tasks you have accomplished and what is next on your plate. For instance, you could post a daily status update to Slack, such as: “Finished reviewing the XYZ page for errors and planning on testing ABC tomorrow.”

By posting a simple status update, you let your team know where you stand and what needs to be done. You also give your project manager a heads-up on progress so they can determine if everything is on schedule.

Keeping in touch with team members on work items is just one way to communicate. You can also communicate with them socially to schedule meetups or improve morale and bonding, which can increase productivity as well.

We have a review of the popular collaboration tool, Microsoft Teams if you are looking for a tool to communicate with your team more effectively: Review of Microsoft Teams.

Ask For Feedback

The distance between you and your colleagues creates the need for increased feedback so you can gauge your performance as a developer. Without feedback and constructive criticism from teammates and management via frequent code reviews, for example, you may not improve your development skills, which will not do you any favors as you look to climb up this (or another company’s) ladder in the future.

As you get feedback, you will probably be asked to give it as well. When giving feedback, remember that the goal is to help others improve versus offending them.

There may come times when you have to give and receive feedback from a developer, project manager, stakeholder, or other team member that you do not see eye to eye with. If this happens, ask for feedback from other, less biased developers, so you truly understand what needs to be improved.

Avoid Multitasking With Home And Work Tasks

Can you get more errands done when working at home? Sure, but you want to avoid mixing errands and other home tasks with work, as it can distort focus, lead to mistakes, and make it harder to concentrate.

If you want to get your laundry done on certain days, fine. Just be sure to do your laundry during a quick break, not when working on something important.

Dress Professionally For Virtual Meetings

If you have a video call with a current or prospective client, be sure to dress the part of a professional. Even though you may code in your pajamas, you want to exude a positive impression when collaborating with others who can impact your bottom line and career trajectory.

Never Stop Learning

As mentioned, one of the biggest benefits of working remotely as a developer is that it can lead to more control over your schedule and increased free time. Use some of that free time to advance your education so you can become a more well-rounded developer. This can increase your value to the team and open the door for better, higher-paying development gigs.

There are several ways to learn new skills or advance your developer education online. You can find courses, one-on-one training, and much more to boost your programming, tech, and even soft skills. Ask your employer if they reimburse online training. If so, you could improve your marketability as a developer without paying a penny out of your own pocket.

We have a list of some the Best Online Courses to Learn C# if you want to improve your C# or .NET programming skills.

What is Code Refactoring?

Code refactoring refers to the process of simplifying and organizing existing code without altering its business functionality. It is a technique used by developers to improve the quality of their code by making it easier to understand, maintain, and extend.

This is done by making small, incremental changes to the code to make it more efficient, easier to read, and less prone to bugs.

Examples of common code refactoring techniques include renaming variables, extracting methods, introducing design patterns, and reducing code duplication. By refactoring code, you can make it easier to maintain, easier to work with, and cleaner without negatively impacting its functionality.

Code refactoring is an ongoing process that should be performed regularly as part of the software development lifecycle (SDLC). It can help to improve the overall quality of the code, reduce the time and effort required for maintenance, and increase the speed of future software development.

Benefits of Code Refactoring

Code refactoring provides several benefits for programmers, including improved code quality, coding efficiency, better performing codebases, and a reduction of technical debt:

• Improved Code Quality: Refactoring helps to improve the quality of the code by making it more readable, maintainable, and less prone to bugs. This makes it easier for developers to understand and work with the code, and reduces the risk of introducing new bugs.
• Increased Development Speed: By improving the quality of the code, refactoring can help to increase the speed of future development. Developers can more easily understand the code and make changes to it, which reduces the time and effort required for maintenance.
• Better Performance: Refactoring can also help to improve the performance of the code. By removing redundant code, code that creates clutter, non- performant code, optimizing algorithms, and reducing complexity, the code can run faster and more efficiently.
• Enhanced Flexibility: Refactoring helps to make the code more flexible and adaptable to change. This allows developers to easily make changes to the code in response to new requirements or changing business needs, without having to start from scratch.
• Reduced Technical Debt: Over time, software systems can accumulate technical debt, which is the cost of maintaining the code over time. Refactoring helps to reduce this technical debt by making the code more maintainable, which reduces the cost of maintaining the code over the long term.

Code Refactoring Tools for Developers

• Multiple Refactoring Options: The tool should be capable of providing a wide range of refactoring options, such as renaming variables, extracting methods, introducing design patterns, and reducing the amount of code duplication. The more options the tool provides, the more flexible it will be to adapt to different coding styles and requirements.
• Code Analysis: The tool should provide code analysis features that can aid the developer in identifying potential issues in the code, such as code smells, performance bottlenecks, and security vulnerabilities. Developers can use the tool to identify and fix bugs or errors in their code more efficiently and at a faster pace.
• Integration with Development Environments: The tool should be easily integrated with the development environment that the developer uses, such as Visual Studio or JetBrains Rider. As a result, the developer will be able to use the tool more efficiently since he will not need to switch between different tools to access it.
• Multi-language support: If the developer is proficient in multiple programming languages, then the tool should support the languages they are proficient in (or the developer may need). In this way, the developer can use the same tool for all their code refactoring needs. This is regardless of the programming language they are using to write the code.
• An easy-to-use interface: The tool should be intuitive to use and navigate and have a user-friendly interface that makes it easy to interact with. This will make it simpler for developers to perform refactoring tasks, even if unfamiliar with the tool.
• Customizable Settings: The tool should allow the developer to customize settings and preferences, such as code style, refactoring options, and code analysis rules. This will help the software developer to tailor the tool in a way that best fits their needs.
• Documentation and Support: The tool should come with comprehensive documentation and support to allow the developer to make the most of the tool’s features and ensure they can utilize it effectively.

C# Nodes in Linked Lists

Note that a node in a linked list is an object that contains two fields; one stores data and the other holds the address of the immediate next node.

What is a Generic

In simple terms, generics allow a developer to use any data type while working with a class or method.

What is a Singly Linked List in C#?

A singly linked list in C# is forward-oriented. That means when a programmer navigates through a list, they can only traverse in one direction. A node in a singly linked list contains its value and the reference of the next node.

Important Notes about Linked Lists in C#

The following are some key notes developers should keep in mind when working with linked lists in C# and .NET software development:

• Linked lists use memory dynamically
• The LinkedList class implements the ICollection, IEnumerable, and ISerializable interfaces
• Removal and reinsertion of nodes can be done in the same list or in another list
• Programmers can store duplicate elements in a C# linked list, provided they are of the same type
• Each node in a generic LinkedList object is of the type LinkedListNode
• Linked lists in C# supports enumerators
• The capacity of a LinkedList is defined as the number of elements it can hold
• Linked lists do not support chaining, splitting, or cycles, making the list safe for inconsistent states

Constructor Methods for C# Linked Lists

C# provides different constructor methods to make writing code more efficient while working with linked lists. Here is a list of C# constructor methods and what they are used for:

• LinkedList(): Initializes a new instance of the LinkedList class
• LinkedList(IEnumerable): Initialize a new instance of the LinkedList class, which contains elements copied from the specified
  IEnumerable
• LinkedList(SerializationInfo, StreamingContext): Initializes a new instance of the LinkedList class, which can be serialized with the specified SerializationInfo and StreamingContext context

Generic Singly Linked List in C# Code Example

To better understand how singly linked lists in C# work, let’s examine a code example. In this scenario, a generic singly linked list is used to store and retrieve elements using a for each loop:

using System;  
using System.Collections.Generic;  
  
public class MyClass  
{  
    public static void Main(string[] args)  
    {    
        var listOfNames = new LinkedList();  
        listOfNames.AddLast("Rigby Deirdre");  
        listOfNames.AddLast("Cymone Ashlee");  
        listOfNames.AddLast("Rylee Shelley");  
        listOfNames.AddLast("Elaine Teresa");  
        listOfNames.AddFirst("Emmanuel Kourtney");     //adding to the first index  
 
        //   Retrieving list elements  
        foreach (var name in listOfNames)  
        {  
           Console.WriteLine(name);  
        }  
    }  
}

Running this code produces the following output:

Emmanuel Kourtney
Rigby Deirdre  
Cymone Ashlee  
Rylee Shelley  
Elaine Teresa

As you may have anticipated, the output list contains Emmanuel Kourtney at the very first location because we added it using the AddFirst() method; the elements added with AddLast() are added at the next subsequent locations of the list.

For our second scenario, let’s consider another code example of the generic list above, in which we instead add the elements before and after a specific node:

using System;  
using System.Collections.Generic;  
  
public class MyClass  
{  
    public static void Main(string[] args)  
    {  
        var listOfNames = new LinkedList();  
        listOfNames.AddLast("Rigby Deirdre");  
        listOfNames.AddLast("Cymone Ashlee");  
        listOfNames.AddLast("Rylee Shelley");  
        listOfNames.AddLast("Elaine Teresa");  
          
        // Inserting a new element before "Rylee"  
        LinkedListNode node= listOfNames.Find("Rylee Shelley");  
        listOfNames.AddBefore(node, "Ken Heath");  
        names.AddAfter(node, "Denton Atkinson");  
  
        //  Iterating list elements  
        foreach (var name in listOfNames)  
        {  
            Console.WriteLine(name);  
        }  
    }  
}

Here is the output:

Rigby Deirdre  
Cymone Ashlee  
Ken Heath
Rylee Shelley
Denton Atkinson
Elaine Teresa

Here, we got the same output, as expected. Ken Heath is added to the list before, and Denton Atkinson is added after, the specific node Rylee Shelley. We accomplished this using the two methods – AddAfter() and AddBefore(), respectively.
