return (C# Reference) 

  • Article

The return statement terminates execution of the method in which it appears and returns control to the calling method. It can also return an optional value. If the method is a void type, the return statement can be omitted.

Example

In the following example, the method A() returns the variable Area as a double value.

// statements_return.cs
using System;
class ReturnTest 
{
    static double CalculateArea(int r) 
    {
        double area = r * r * Math.PI;
        return area;
    }

    static void Main() 
    {
        int radius = 5;
        Console.WriteLine("The area is {0:0.00}", CalculateArea(radius));
    }
}

Output

The area is 78.54
