En tredje RectangleF struktur vars storlek representerar det överlappande området för de två angivna rektanglarna.

Exempel

Det här exemplet är utformat för användning med Windows Forms och kräver PaintEventArgse, ett OnPaint händelseobjekt. Koden skapar två RectangleF objekt och ritar dem till skärmen i svart och rött. Observera att de måste konverteras till Rectangle objekt i ritningssyfte. Sedan skapar koden en tredje RectangleF med hjälp av Intersect metoden, konverterar den till en Rectangleoch drar den till skärmen i blått. Observera att den tredje (blå) rektangeln är överlappningsområdet för de andra två rektanglarna:

public:
   void RectangleFIntersectExample( PaintEventArgs^ e )
   {
      // Create two rectangles.
      RectangleF firstRectangleF = RectangleF(0,0,75,50);
      RectangleF secondRectangleF = RectangleF(50,20,50,50);

      // Convert the RectangleF structures to Rectangle structures and draw them to the
      // screen.
      Rectangle firstRect = Rectangle::Truncate( firstRectangleF );
      Rectangle secondRect = Rectangle::Truncate( secondRectangleF );
      e->Graphics->DrawRectangle( Pens::Black, firstRect );
      e->Graphics->DrawRectangle( Pens::Red, secondRect );

      // Get the intersection.
      RectangleF intersectRectangleF = RectangleF::Intersect( firstRectangleF, secondRectangleF );

      // Draw the intersectRectangleF to the screen.
      Rectangle intersectRect = Rectangle::Truncate( intersectRectangleF );
      e->Graphics->DrawRectangle( Pens::Blue, intersectRect );
   }

public void RectangleFIntersectExample(PaintEventArgs e)
{
             
    // Create two rectangles.
    RectangleF firstRectangleF = new RectangleF(0, 0, 75, 50);
    RectangleF secondRectangleF = new RectangleF(50, 20, 50, 50);
             
    // Convert the RectangleF structures to Rectangle structures and draw them to the
             
    // screen.
    Rectangle firstRect = Rectangle.Truncate(firstRectangleF);
    Rectangle secondRect = Rectangle.Truncate(secondRectangleF);
    e.Graphics.DrawRectangle(Pens.Black, firstRect);
    e.Graphics.DrawRectangle(Pens.Red, secondRect);
             
    // Get the intersection.
    RectangleF intersectRectangleF =
        RectangleF.Intersect(firstRectangleF,
        secondRectangleF);
             
    // Draw the intersectRectangleF to the screen.
    Rectangle intersectRect =
        Rectangle.Truncate(intersectRectangleF);
    e.Graphics.DrawRectangle(Pens.Blue, intersectRect);
