Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgse, which is a parameter of the Paint event handler. The code clears the drawing surface of the Graphics and sets the background color to the system-defined teal color.

private:
   void ClearColor( PaintEventArgs^ e )
   {
      // Clear screen with teal background.
      e->Graphics->Clear( Color::Teal );
   }
private void ClearColor(PaintEventArgs e)
{
    // Clear screen with teal background.
    e.Graphics.Clear(Color.Teal);
}
Private Sub ClearColor(ByVal e As PaintEventArgs)

    ' Clear screen with teal background.
    e.Graphics.Clear(Color.Teal)
End Sub

Remarks

The Clear method clears the state of the graphics object and should not be called when the graphics object cannot be updated. For example, if the Clear method is called on a secure desktop in a terminal server session, an ExternalException may occur, leaving the Graphics object in an inconsistent state.
