return (C# Reference)

Updated: July 2008

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.

If the return statement is inside a try block, the finally block, if one exists, will be executed before control returns to the calling method.

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

class ReturnTest 
{
    static double CalculateArea(int r) 
    {
        double area = r * r * Math.PI;
        return area;
    }

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

        // Keep the console open in debug mode.
        Console.WriteLine("Press any key to exit.");
        Console.ReadKey();
    }
}
// Output: The area is 78.54
