I'm not sure what you're talking about, but here's an example where main passes a value to some function and then get the result back.

(Toggle Plain Text)

public static void main(string[] args)
{ 
    int TheValue = 5;                          //originally, TheValue=5
    TheValue = increase_it(TheValue);   //now TheValue=10
}

public int  increase_it(int AnyValue)
{
    AnyValue = AnyValue + 5;  //increment the received value by 5
    return AnyValue;              //return the new value
}

This is only one way to do it, passing by reference is another.
