Creates a rectangle that is exactly large enough to include the specified rectangle and the specified point.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public static Rect Union(
	Rect rect,
	Point point
)

Parameters

rect
Type: System.Windows.Rect
The rectangle to include.
point
Type: System.Windows.Point
The point to include.

Return Value

Type: System.Windows.Rect
A rectangle that is exactly large enough to contain the specified rectangle and the specified point.

The following example shows how to use the Union(Rect, Point) method to create a rectangle that is exactly large enough to contain a given rectangle and a given Point.


private Rect unionExample3()
{
    // 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.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // The Union method expands the current rectangle exactly enough to contain 
    // the specified rectangle and the specified Point. In this example, returnRect 
    // expands to a location of 0,0 and a size of 250,60.
    Rect returnRect = Rect.Union(myRectangle2, new Point(250,60));

    // Returns 0,0,250,60
    return returnRect;

}
