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 performs the following actions:

  • Creates a black pen.

  • Creates an array of three rectangles.

  • Draws the rectangles to the screen.

public void DrawRectanglesRectangle(PaintEventArgs e)
{
             
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Create array of rectangles.
    Rectangle[] rects =
             {
                 new Rectangle( 0,   0, 100, 200),
                 new Rectangle(100, 200, 250,  50),
                 new Rectangle(300,   0,  50, 100)
             };
             
    // Draw rectangles to screen.
    e.Graphics.DrawRectangles(blackPen, rects);
}

public void DrawRectanglesRectangle(PaintEventArgs e) 
{
    // Create pen.
    Pen blackPen =  new Pen(Color.get_Black(), 3);

    // Create array of rectangles.
    Rectangle rects[] =  {new Rectangle(0, 0, 100, 200), new Rectangle(100,
                            200, 250, 50), new Rectangle(300, 0, 50, 100)};

    // Draw rectangles to screen.
    e.get_Graphics().DrawRectangles(blackPen, rects);
} //DrawRectanglesRectangle
