What are postfix operators in C#?

The increment operator is ++ operator. If used as postfix on a variable, the value of the variable is first returned and then gets incremented by 1. It is called Postfix increment operator. In the same way, the decrement operator works but it decrements by 1.

For example,

a++;

The following is an example showing how to work with postfix operator −

Example

using System;

class Program {
   static void Main() {
      int a, b;

      a = 10;
      Console.WriteLine(a++);
   
      b = a;
      Console.WriteLine(a);
      Console.WriteLine(b);
   }
}

Output

10
11
11
