Find a cut full code, but will not use, who saved about newcomers ?

public static Bitmap CopyPrimaryScreen ()
{
Screen s = Screen.PrimaryScreen;
Rectangle r = s.Bounds;
int w = r.Width;
int h = r.Height;
Bitmap bmp = new Bitmap (w, h);
Graphics g = Graphics.FromImage (bmp);
g.CopyFromScreen
(
new Point (0, 0),
new Point (0, 0),
new Size (w, h)
);
return bmp;
}
