Question

I have done some digging and found some code that can run the application directly to full-screen mode during runtime, I was wondering if there is any way to switch back to windowed mode by pressing “Esc” ?

Here is my code for full-screen mode:

private void Window_Loaded(object sender, RoutedEventArgs e) {
    WindowStyle = WindowStyle.None;
    Topmost = true;
    WindowState = WindowState.Maximized;
}

Set this.KeyPreview = true;

And this.KeyDown += new System.Windows.Forms.KeyEventHandler(Form_KeyDown);

    private void Form_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Escape)
        {
            this.WindowState = FormWindowState.Normal;
        }
    }
