The PointConverter class is typically used for creating a design-time experience for controls that have properties that are of type Point, and is used to convert points to strings for display in a designer and to convert strings entered in a designer to a Point object. Access this class through the TypeDescriptor object.

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);
}
