VERY Easy C# Question

Hello, i just began playing with C#. I’m used to console C/C++ programming. I am simply wondering how I can pass a text string from one .cs form to another.cs

I have a typical login window, which consists of some textboxes, labels and buttons.

On click I want the event handler to pass the user name and password to a function in a different .cs file that is part of the project, one that holds the authenticate function logic.

I want to do something like this

Form1.cs
...
private void OK_Click(object sender, System.EventArgs e)
                  {
                   authenticate(UserName.Text, Password.Text);
}
...

---------------------------
Authenticate.cs

...
authenticate(string username, string password)
{
            if( username == ...etc etc )
return etc;
}
...

Could some one please explain and show with a basic example how I could pass the text string.

Thanks in advance! =)

I need to separate the process logic from Form1.cs

i tried something like this but it didnt work, how can i state the retrun type, or in other words how do i get it to work?

Form1.cs
...
private void OK_Click(object sender, System.EventArgs e)
                  {
Class1 = new Class1(UserName.Text); }
...

------------------------
Class1.cs
...
public class Class1
      { public int Check(string uname)
            {
                  if(uname == "aa")
                        return 1;
                  else
                        return 0;
            }
      }

i read a book and got the right syntax

Class1 obj = new Class1();
if(obj.Check(UserName.Text))...

you need to either declare an instance of the class or make it static. I see you know how to declare the instance, and the example below is for static.

public static class class1
{
public static int Check(string uname)
{
if(uname == "aa")
return 1;
else
return 0;
}
}

now in your ok_click you can do this
int Valid = Class1.Check(UserName.Text);
