Subtract(Point, Point)

從指定的 Point 減去另一個指定的 Point 並以 Vector 傳回差數。

Subtract(Point, Vector)

從指定的 Vector 減去指定的 Point 並傳回產生的 Point

Subtract(Point, Point)

從指定的 Point 減去另一個指定的 Point 並以 Vector 傳回差數。

public:
 static System::Windows::Vector Subtract(System::Windows::Point point1, System::Windows::Point point2);
public static System.Windows.Vector Subtract (System.Windows.Point point1, System.Windows.Point point2);
static member Subtract : System.Windows.Point * System.Windows.Point -> System.Windows.Vector
Public Shared Function Subtract (point1 As Point, point2 As Point) As Vector

參數

point1
Point

減去 point2 的點。

point2
Point

要從 point1 減去的點。

傳回

Vector

point1point2 之間的差數。

範例

下列範例示範如何使用靜態 Subtract 方法從另一個 Point 減去 Point

private Vector subtractExample2()
{

    Point point1 = new Point(10, 5);
    Point point2 = new Point(15, 40);

    // Subtracts a Point from a Point using the static Subtract method
    // and returns the difference as a Vector.
    // vectorResult is equal to (-5, -35)
    Vector vectorResult = Point.Subtract(point1, point2);

    return vectorResult;
}
Private Function subtractExample2() As Vector

    Dim point1 As New Point(10, 5)
    Dim point2 As New Point(15, 40)

    ' Subtracts a Point from a Point using the static Subtract method
    ' and returns the difference as a Vector.
    ' vectorResult is equal to (-5, -35)
    Dim vectorResult As Vector = Point.Subtract(point1, point2)

    Return vectorResult

End Function
