Examples

The following code example demonstrates how to use the MakeInfinite method. This example is designed to be used with Windows Forms. Create a form and paste the following code into it. Call the FillEmptyRegion method in the form's Paint event-handling method, passing e as PaintEventArgs.

private void FillInfiniteRegion(PaintEventArgs e)
{
    // Create a region from a rectangle.
    Rectangle originalRectangle = new Rectangle(40, 40, 40, 50);
    Region smallRegion = new Region(originalRectangle);

    // Call MakeInfinite.
    smallRegion.MakeInfinite();

    // Fill the region in red and draw the original rectangle
    // in black. Note that the entire form is filled in.
    e.Graphics.FillRegion(Brushes.Red, smallRegion);
    e.Graphics.DrawRectangle(Pens.Black, originalRectangle);
}
