Esempi

Nell'esempio seguente viene illustrato come sottrarre Point un oggetto Point da un altro Vector e restituire un oggetto utilizzando l'operatore di overload (-).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
