Point.Subtraction Operador

Definição

Namespace:

System.Windows

Assembly:

WindowsBase.dll

Subtrai o Vector ou Point especificado do Point especificado.

Sobrecargas

Subtraction(Point, Point)	Subtrai o Point especificado de outro Point especificado e retorna a diferença como um Vector.
Subtraction(Point, Vector)	Subtrai o Vector especificado do Point especificado e retorna o Point resultante.

Subtraction(Point, Point)

Subtrai o Point especificado de outro Point especificado e retorna a diferença como um 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

Parâmetros

point1

Point

O ponto do qual point2 é subtraído.

point2

Point

O ponto do qual subtrair point1.

Retornos

Vector

A diferença entre point1 e point2.

Exemplos

O exemplo a seguir mostra como subtrair um Point de outro Point e retornar um Vector usando o operador sobrecarregado (-).

      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

Exemplos

O exemplo a seguir mostra como subtrair um Vector de um Point operador que usa o (-) sobrecarregado.

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

End Function
