What is a void return type?

Hello Rahul, as the name itself says return type... It means you are returning something from your program.... So there are different types of returning values... Those types can be:

1. Any data type from C#

2. Object/Collections/.... It can simply be anything.

3. Void - This is used if you feel that your program does not require to return anything, then in that case "void" is used....

Here's a small example :

using System

public class Mathematics
{
        public static void Main(String[] args)
        {
                int value = Add();        // Integer value is returned by this method.
                Console.WriteLine(value);

                Multiply();
        }

        public int Add()        // Returns an Integer
        {
                int x = 5 + 5;
                return x;
        }

        public void Multiply()        // Returns nothing
        {
                int y = 5 * 5;
                Console.WriteLine(y);
        }
}

So the Add method returns an integer where as the Multiply method returns nothing. In short my point here is that returning any value depends upon the logic of your program and the requirement.

Hope this helps u out.

Hi Rahul,

When void is used in method, it Specifies that the method that does not return a value.

Hi

When used void as the return type for a method, void specifies that the method does not return a value.
