定义

从指定的 Point 中减去指定的 VectorPointSubtracts the specified Point or Vector from the specified Point.

重载

Subtract(Point, Point)

从指定的 Point 中减去另一个指定的 Point 并将差作为 Vector 返回。Subtracts the specified Point from another specified Point and returns the difference as a Vector.

Subtract(Point, Vector)

从指定的 Vector 减去指定的 Point 并返回所得的 PointSubtracts the specified Vector from the specified Point and returns the resulting Point.

Subtract(Point, Point)

从指定的 Point 中减去另一个指定的 Point 并将差作为 Vector 返回。Subtracts the specified Point from another specified Point and returns the difference as a Vector.

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

参数

point1
Point

要从中减去 point2 的点。The point from which point2 is subtracted.

point2
Point

要从 point1 中减去的点。The point to subtract from point1.

返回

point1point2 之间的差值。The difference between point1 and point2.

示例

下面的示例演示如何使用静态Point Subtract方法从中Point减去另一个。The following example shows how to subtract a Point from another Point using the static Subtract method.

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
