L’exemple suivant montre comment utiliser la méthode pour développer le Union(Point) rectangle actuel exactement suffisamment pour contenir un donné Point.

private Rect unionExample1()
{
    // 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);

    // The Union method expands the current rectangle exactly enough to contain 
    // the specified point. myRectangle expands to a location of 0,0 and a size
    // of 210,55.
    myRectangle.Union(new Point(0,0));

    // Returns 0,0,210,55

Rect

Un rectangle qui est exactement assez grand pour contenir le rectangle et le point spécifiés.

L’exemple suivant montre comment utiliser la Union(Rect, Point) méthode pour créer un rectangle qui est exactement assez grand pour contenir un rectangle donné et un rectangle donné Point.

private Rect unionExample3()

    // Initialize new rectangle.
    Rect myRectangle = new Rect();

    // Set the Size property of the rectangle with a width of 200

    myRectangle3.Location = new Point(210, 60);
    myRectangle3.Size = new Size(50, 50);

    // The Union method expands the current rectangle exactly enough to contain 
    // the two specified rectangles. In this example, returnRect expands to 
    // a location of 0,0 and a size of 260,110.
