Union(Point)
將目前矩形展開為剛好可以包含指定的點。
public:
void Union(System::Windows::Point point);
public void Union (System.Windows.Point point);
member this.Union : System.Windows.Point -> unit
Public Sub Union (point As Point)
參數
- point
- Point
要包含的點。
範例
下列範例示範如何使用 Union(Point) 方法來展開目前矩形,完全足以包含指定的 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;
