Rect.Offset Method (Rect, Vector)


Returns a rectangle that is offset from the specified rectangle by using the specified vector.

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

public static Rect Offset(
	Rect rect,
	Vector offsetVector


Type: System.Windows.Rect

The original rectangle.

Type: System.Windows.Vector

A vector that specifies the horizontal and vertical offsets for the new rectangle.

Return Value

Type: System.Windows.Rect

The resulting rectangle.

Exception Condition

rect is Rect.Empty.

Calling this method with an empty rectangle (Rect.Empty) is not allowed.

The following example shows how to use the Offset(Rect, Vector) method to change the position of a rectangle.

private Point offsetExample3()
    // 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 a vector to use to offset the position of the rectangle.
    Vector vector1 = new Vector(20, 30);

    // The Offset method translates the specified rectangle by the specified amount 
    // and returns the resulting Rect. 
    // resultRect location changed from 10,5 to 30,35.
    Rect resultRect = Rect.Offset(myRectangle, vector1);

    // This rectangle's location changed from 10,5 to 30,35.
    return resultRect.Location;
