{
// Create two rectangles and draw them to the screen.
RectangleF firstRectangleF = new RectangleF(0, 0, 75, 50);
RectangleF secondRectangleF = new RectangleF(100, 100, 20, 20);
// Convert the RectangleF structures to Rectangle structures and draw them to the
// screen.
Rectangle firstRect = Rectangle.Truncate(firstRectangleF);
Rectangle secondRect = Rectangle.Truncate(secondRectangleF);
e.Graphics.DrawRectangle(Pens.Black, firstRect);
