C# Comments

Like many other programming languages. It’s good practice to include the comments in our c# code to provide detailed information about the functionality, like what a specific block or line of code can do. It will benefit anyone else who examines the code later.

In c#, we can include the comments anywhere in the program without affecting our code. The comments in c# do not affect an application's performance because the comments won’t be compiled and executed by the compiler.

There are three types of comments available, these are

• Single-line Comments
• Multi-line Comments
• XML Comments

C# Single Line Comment

The single line comment starts with // (double slash).

Let's see an example of single line comment in C#.

using System;
					
public class Program
{
	public static void Main()
	{ 
		// Let's declare and print variable in C#   
		int x=30;  
		Console.WriteLine(x);  
	}
}

C# Multi Line Comment

The C# multi line comment is used to comment multiple lines of code.

It is surrounded by slash and asterisk (/* ….. */).

Let's see an example of multi line comment in C#.

using System;
					
public class Program
{
	public static void Main()
	{ 
		/* Let's declare and  
          print variable in C#. */   
		int x=30;  
		Console.WriteLine(x);  
	}
}

C# XML Comments

In C# an XML Comment is a special type of comments, and these will be added above the definition of any user-defined type or member.

In c#, the XML Comments are defined by using /// (triple forward slashes) and with XML formatted comment body.

Following is the syntax of defining the XML comments in the c# programming language.

using System;
					
public class Program
{
	public static void Main()
	{  
		int x=30;  
		string msg = "maxcsharp";
		Console.WriteLine(x); 
		DisplayMessage(msg);
	}
	///<summary>
	/// Method to Display Welcome Message
	///</summary>
	///<param name="message"></param>
	public static void DisplayMessage(string message)
	{
		Console.WriteLine(message);
	}
}
