Draws a series of rectangles specified by Rectangle structures.

public:
 void DrawRectangles(System::Drawing::Pen ^ pen, cli::array <System::Drawing::Rectangle> ^ rects);
public:
 void DrawRectangles(System::Drawing::Pen ^ pen, ... cli::array <System::Drawing::Rectangle> ^ rects);
public void DrawRectangles (System.Drawing.Pen pen, System.Drawing.Rectangle[] rects);
public void DrawRectangles (System.Drawing.Pen pen, params System.Drawing.Rectangle[] rects);
member this.DrawRectangles : System.Drawing.Pen * System.Drawing.Rectangle[] -> unit
Public Sub DrawRectangles (pen As Pen, rects As Rectangle())
Public Sub DrawRectangles (pen As Pen, ParamArray rects As Rectangle())

Parameters

pen
Pen

Pen that determines the color, width, and style of the outlines of the rectangles.

rects
Rectangle[]

Array of Rectangle structures that represent the rectangles to draw.

Exceptions

pen is null.

-or-

rects is null.

rects is a zero-length array.

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, 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 = gcnew Pen( Color::Black,3.0f );

      // Create array of rectangles.
      array<Rectangle>^ rects = {Rectangle(0,0,100,200),Rectangle(100,200,250,50),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.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 Sub DrawRectanglesRectangle(ByVal e As PaintEventArgs)

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create array of rectangles.
    Dim rects As Rectangle() = {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)
End Sub
