probably a very simple question

[John Salerno]

I have two files:

public class Tester
{
public static void Main()
{
Program begin = new Program();
begin.StartCalculator();
}
}

AND

public class Program
{
public void StartCalculator()
{
System.Console.WriteLine("Hello world");
}
}

This works, but when I change the body of Main() to simply:

StartCalculator();

and make the StartCalculator() method static, I get:

The name 'StartCalculator' does not exist in the current context

What does that mean, and why must I call the method on an object for the
program to run?

Hi,

You just need to tell it what class contains the StartCalculator method.

....
public static void Main()
{
Program.StartCalculator();
}

With just StartCalculator(), the compiler was searching for the method in the
Tester class.

Best regards,

Rodger

Ack, so simple! Thanks!

Is there a preferred way to do this? (static or instance?)

Hi,

It depends on what you are trying to accomplish.

There is nothing wrong with calling a static method from Main and letting it be
the one initializing your app.
