The following code example demonstrates how to use the PointConverter and the op_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 Sub ShowPointConverter(ByVal e As PaintEventArgs) ' Create the PointConverter. Dim converter As System.ComponentModel.TypeConverter = _ System.ComponentModel.TypeDescriptor.GetConverter(GetType(Point)) Dim point1 As Point = _ CType(converter.ConvertFromString("200, 200"), Point) ' Use the subtraction operator to get a second point. Dim point2 As Point = Point.op_Subtraction(point1, _ New Size(190, 190)) ' Draw a line between the two points. e.Graphics.DrawLine(Pens.Black, point1, point2) End Sub
private void ShowPointConverter(PaintEventArgs e)
{
// Create the PointConverter.
PointConverter converter = new PointConverter();
Point point1 = (Point)converter.ConvertFromString("200, 200");
// Use the subtraction operator to get a second point.
Point point2 = Point.op_Subtraction(point1 , new Size(190, 190));
// Draw a line between the two points.
e.get_Graphics().DrawLine(Pens.get_Black(), point1, point2);
} //ShowPointConverter
