Comments in C#

Comments are used for explaining the code and are used in a similar manner as in Java, C or C++. Compilers ignore the comment entries and do not execute them. Generally, programming languages contain two types of comments but in C#, there are 3 Types of comments :

1. Single Line Comments : It is used to comment a single line. These comment can be written in a separate line or along with the codes in the same line. But for better understanding always use the comment in a separate line.
   Syntax :

   // Single Line Comments

2. Multiline Comments : It is used to comment more than one line. Generally this is used to comment out an entire block of code statements.
   Syntax :

   /* Multiline
   Comment */
   

   Example :

   // C# program to demonstrate the single
   // line and multiline comments
   using System;
   
   namespace HelloGeeksApp {
   
   class HelloGeeks {
   
       // Single Line Comment -- Function to print Message
       public static void Message(string message)
       {
           Console.WriteLine(message);
       }
   
       // Main function
       static void Main(string[] args)
       {
   
           /* Multiline Comment --
              Define a variable of
              string type and assign
              value to it*/
           string msg = "GeeksforGeeks";
   
           // Calling function
           Message(msg);
       }
   }
   }
   Output:

   GeeksforGeeks
   

3. XML Documentation Comments : It is a special type of comment in C# and used to create the documentation of C# code by adding XML elements in the source code. XML elements are added in XML Documentation Comments of C#. For more details refer to XML Documentation Comments in C#
   Syntax :

   /// <summary>
   /// This class does something of program Summary.
   /// </summary>
   

   Example :

   // C# program to demonstrate XML
   // Documentation Comments
   using System;
   
   namespace HelloGeeksApp {
   
   class HelloGeeks {
   
       /// <summary>
       /// Method to Display Geeksforgeeks Message
       /// </summary>
       /// <param name="Geeksforgeeks"></param>
       public static void Message(string message)
       {
           Console.WriteLine(message);
       }
   
       // Main function
       static void Main(string[] args)
       {
   
           /* Define a variable of
              string type and assign
              value to it*/
           string msg = "GeeksforGeeks";
   
           // Calling function
           Message(msg);
       }
   }
   }
   Output:

   GeeksforGeeks
   

Note : The <summary> tag provides the information about the defined a type or member and <param> tag is method parameters.
