Question

When we write a method, say an easy one like

  void myMethod()
    {
    // code here
    // 
    }

and we call it from within Main(), it’s done essentially this way:

Program myProgram = new Program ();
myProgram.myMethod();

Obviously, myProgram is entirely arbitrary (taking into consideration, of course, coding conventions) but what’s up with the reference to Program?

Answer 1

You are declaring your method myMethod inside a class called Program. Since your method is not a static method (i.e. it is not static void myMethod()) it requires an instance of Program in order to work. Therefore you need to create a new instance of Program in order to invoke myProgram.myMethod() on it. If myMethod were static, you could have called it simply by Program.myMethod() or, since you’re already inside that class to begin with, myMethod() (since the current class name is implied for static methods).
