Overloads

DrawRectangles(Pen, Rectangle[]) DrawRectangles(Pen, Rectangle[]) DrawRectangles(Pen, Rectangle[])

Draws a series of rectangles specified by Rectangle structures.

DrawRectangles(Pen, RectangleF[]) DrawRectangles(Pen, RectangleF[]) DrawRectangles(Pen, RectangleF[])

Draws a series of rectangles specified by RectangleF structures.

DrawRectangles(Pen, Rectangle[]) DrawRectangles(Pen, Rectangle[]) DrawRectangles(Pen, Rectangle[])

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, System.Drawing.Rectangle[] rects);
member this.DrawRectangles : System.Drawing.Pen * System.Drawing.Rectangle[] -> unit

Parameters

pen
Pen 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

rects is a zero-length array.

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 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

DrawRectangles(Pen, RectangleF[]) DrawRectangles(Pen, RectangleF[]) DrawRectangles(Pen, RectangleF[])
