Subtraction(Point, Vector)

從指定Vector值減去指定Point值，並返回結果 Point。

Subtraction(Point, Point)

從另一個指定Point值Point中減去，並返回差值為 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

參數

point1
Point

從中減去的 point2 點。

point2
Point

從中減 point1去的點。

傳回

Vector

與point1的差異point2。

範例

以下範例展示了如何從另一個 Point a 減去 a Point 並利用超載 （-） 運算子返回 aVector。

      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

範例

以下範例展示了如何使用過載（-）運算子從 a Vector 中減去 aPoint。

private Point overloadedSubtractionOperatorExample1()
{

    Point point1 = new Point(10, 5);
    Vector vector1 = new Vector(20, 30);

    // Subtracts a Vector from a Point using the overloaded subtraction (-) operator.
    // pointResult is equal to (-10, -25)
    Point pointResult = point1 - vector1;
    
    return pointResult;
}

Private Function overloadedSubtractionOperatorExample1() As Point

    Dim point1 As New Point(10, 5)
    Dim vector1 As New Vector(20, 30)

    ' Subtracts a Vector from a Point using the overloaded subtraction (-) operator.
    ' pointResult is equal to (-10, -25)
    Dim pointResult As Point = point1 - vector1

    Return pointResult
