The statements that the compiler does not execute are called the Comments in C#. It is mostly used to give a short explanation of a part of the code or for a variable, a method or a class. It is also sometimes used to hide the program code. In C#, we can use either of the two types of comments.

• Single Line comment
• Multi-Line comment

## C# Single Line Comment:

To comment a single line of code, the single-line comment is used in C#, which starts with a double slash ( // ).

Example:

using System; public class Example { public static void Main(string[] args) { char ch = 'a'; //Here, ch is a character Console.WriteLine(ch); } }

Output:

a


Explanation:

In the above example, we are displaying the use of the single-line comment in C#.

## C# Multi-Line Comment:

To comment the multiple lines of code, the multi-line comment is used in C#, which starts and ends with a slash and asterisk (/* ….. */).

Example:

using System; public class Example { public static void Main(string[] args) { /* Here we are declaring and printing a character in C#. */ char ch = 'a'; Console.WriteLine(ch); } }

Output:

a


Explanation:

In the above example, we are displaying the use of the multi-line comment in C#.
