Subtraction(Point, Point) Subtraction(Point, Point) Subtraction(Point, Point) Subtraction(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.

Subtraction(Point, Vector) Subtraction(Point, Vector) Subtraction(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.

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

参数

point1
Point Point Point Point

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

point2
Point Point Point 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Point从另一个Point中减去, 并Vector使用重载的 (-) 运算符返回。The following example shows how to subtract a Point from another Point and return a Vector using the overloaded (-) operator.

      private Vector overloadedSubtractionOperatorExample2()
      {

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

          // Subtracts a Point from another Point using the overloaded subtraction (-)
          // operator and returns the difference as a Vector.
          // vectorResult is equal to (-5, -35).
          Vector vectorResult = point1 - point2;

          return vectorResult;

      }
Private Function overloadedSubtractionOperatorExample2() As Vector

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

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

    Return vectorResult

End Function
