The following code example demonstrates how to use the PointConverter and the Subtraction operator. This example is designed to be used with Windows Forms. Paste this code into a form and call the ShowPointConverter method when handling the form's Paint event, passing e as PaintEventArgs.

private void ShowPointConverter(PaintEventArgs e)
{

    // Create the PointConverter.
    System.ComponentModel.TypeConverter converter = 
        System.ComponentModel.TypeDescriptor.GetConverter(typeof(Point));

    Point point1 = (Point) converter.ConvertFromString("200, 200");

    // Use the subtraction operator to get a second point.
    Point point2 = point1 - new Size(190, 190);

    // Draw a line between the two points.
    e.Graphics.DrawLine(Pens.Black, point1, point2);
}
