public sealed class SystemPens

The following code example creates points and sizes using several of the overloaded operators defined for these types. It also demonstrates how to use the SystemPens class.

This example is designed to be used with Windows Forms. Create a form that contains a Button named subtractButton. Paste the code into the form and call the CreatePointsAndSizes method from the form's Paint event-handling method, passing e as PaintEventArgs.

private void CreatePointsAndSizes(PaintEventArgs e)

    // Create the starting point.
    Point startPoint = new Point(subtractButton.Size);

    // Use the addition operator to get the end point.
    Point endPoint = startPoint + new Size(140, 150);

    // Draw a line between the points.
    e.Graphics.DrawLine(SystemPens.Highlight, startPoint, endPoint);

    // Convert the starting point to a size and compare it to the 
    // subtractButton size.  
    Size buttonSize = (Size)startPoint;
    if (buttonSize == subtractButton.Size)

        // If the sizes are equal, tell the user.
        e.Graphics.DrawString("The sizes are equal.", 
            new Font(this.Font, FontStyle.Italic), 
            Brushes.Indigo, 10.0F, 65.0F);
