The following example shows how to use the Union(Point) method to expand the current rectangle exactly enough to contain a given 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
    return myRectangle;
