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 :

   filter_none

   edit
   close

   play_arrow

   link
   brightness_4
   code

   // 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);     } } }

   filter_none

   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 :

   filter_none

   edit
   close

   play_arrow

   code

   // 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);     } } }

   chevron_right

   filter_none

   Output:

   GeeksforGeeks
   

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