Your code must start somewhere non-static - for example, a
button_click event handler. From there, you can call a static method
and just pass the thing in.
Suppose the following:
You have a textbox with ID txt1. The code gets started by clicking
btn1.
public void btn1_Click(object sender, EventArgs e)
{
DoSomething(txt1);
}
public static void DoSomething(TextBox textBox)
{
textBox.Text = "AAA";
}
Working with the form is a little different - if you can stick with
the textbox only, that will be the easiest and probably the most
readable.
