How do I find what screen the application is running on in C#

Question

How do I determine what screen my application is running on?

Answer 1

This should get you started. Get a Button and a listbox on a Form and put this in the Button_Click:

listBox1.Items.Clear();
foreach (var screen in Screen.AllScreens)
{
    listBox1.Items.Add(screen);
}
listBox1.SelectedItem = Screen.FromControl(this);            

The answer is in the last line, remember that a Form is a Control too.

Answer 2

The System.Windows.Forms.Screen class provides this functionaility.

For example:

Screen s = Screen.FromPoint(p);

where p is a Point somewhere on your application (in screen coordinates).
