Définition

Espace de noms:

System.Windows

Assembly:

WindowsBase.dll

Trouve l'intersection de deux rectangles.

Surcharges

Intersect(Rect)	Trouve l'intersection du rectangle actuel et du rectangle spécifié, et stocke le résultat comme le rectangle actuel.
Intersect(Rect, Rect)	Renvoie l'intersection des rectangles spécifiés.

Intersect(Rect)

Trouve l'intersection du rectangle actuel et du rectangle spécifié, et stocke le résultat comme le rectangle actuel.

public:
 void Intersect(System::Windows::Rect rect);

public void Intersect (System.Windows.Rect rect);

member this.Intersect : System.Windows.Rect -> unit

Public Sub Intersect (rect As Rect)

Paramètres

rect

Rect

Le rectangle devant trouver l'intersection avec le rectangle actuel.

Exemples

L’exemple suivant montre comment utiliser la Intersect(Rect) méthode pour rechercher l’intersection de deux rectangles et stocker le résultat sous forme de rectangle.

private Rect intersectExample1()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // The Location property specifies the coordinates of the upper left-hand 
    // corner of the rectangle. 
    myRectangle.Location = new Point(10, 5);

    // Set the Size property of the rectangle with a width of 200
    // and a height of 50.
    myRectangle.Size = new Size(200, 50);

    // Create second rectangle to compare to the first.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // Intersect method finds the intersection between the current rectangle and the 
    // specified rectangle, and stores the result as the current rectangle. If no 
    // intersection exists, the current rectangle becomes the Empty rectangle. 
    // myRectangle now has a size of 190,45 and location of 10,5. 
    myRectangle.Intersect(myRectangle2);

    // myRectangle has been changed into the intersection area between the old myRectangle
    // and myRectangle2 (new size of 190,45 and new location of 10,5).
    return myRectangle;
}

Remarques

Si aucune intersection n’existe, le rectangle actuel devient Rect.Empty.
