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)
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
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
