Subtraction(Point, Point)

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

Subtraction(Point, Vector)

從指定的 Vector 減去指定的 Point 並傳回產生的 Point

Subtraction(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 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

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

下列範例示範如何從另一 PointPoint 減去 ,並使用多載的 (-) 運算子傳回 Vector

      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

下列範例示範如何使用多載的 (-) 運算子從 Point 減去 Vector

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)
