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

private Point offsetExample4()
    // 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 horizontal 
    // and vertical amounts and returns the resulting Rect. 
    // resultRect location changed from 10,5 to 30,35.
    Rect resultRect = Rect.Offset(myRectangle, 20, 30);

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