Point.Subtraction Operatore

Definizione

Spazio dei nomi:

System.Windows

Assembly:

WindowsBase.dll

Sottrae l'oggetto Vector o l'oggetto Point specificato dall'oggetto Point indicato.

Overload

Subtraction(Point, Point)	Sottrae l'oggetto Point specificato da un altro oggetto Point specificato e restituisce la differenza come oggetto Vector.
Subtraction(Point, Vector)	Sottrae l'oggetto Vector specificato dall'oggetto Point indicato e restituisce l'oggetto Point che ne risulta.

Subtraction(Point, Point)

Sottrae l'oggetto Point specificato da un altro oggetto Point specificato e restituisce la differenza come oggetto 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

Parametri

point1

Point

Punto dal quale viene sottratto l'oggetto point2.

point2

Point

Punto da cui sottrarre l'oggetto point1.

Restituisce

Vector

Differenza tra point1 e point2.

Esempio

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

      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
