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())

Parametri

pen
Pen

Pen che determina il colore, la larghezza e lo stile dei contorni dei rettangoli.

rects
Rectangle[]

Matrice di strutture Rectangle che rappresentano i rettangoli da disegnare.

Eccezioni

pen è null.

-o-

rects è null.

rects è una matrice di lunghezza zero.

Esempio

L'esempio di codice seguente è progettato per l'uso con Windows Form e richiede PaintEventArgse, che è un parametro del gestore eventi Paint. Il codice esegue le azioni seguenti:

  • Crea una penna nera.

  • Crea una matrice di tre rettangoli.

  • Disegna i rettangoli sullo schermo.

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), _
