You can't "call" a class. You can call a method, or create an instance
of a class, and then call a method from that class. Or you could call a
static method. Now, what do you actually want to do?

(I would strongly advise learning the basics of C# before doing GUI
coding, btw. GUI coding has all kinds of added complications which will
be even harder to cope with if you're not confident about the basic
platform.)

Oh No!

public void Button1_Click()
{
myClass c = new myClass()
c.MyMethod()
}

public class myClass
{
public void myMethod()
{
// Do Something
}
}

But you should (both) follow Jon Skeet's advice.
