public:
 static System::Windows::Vector operator -(System::Windows::Vector vector1, System::Windows::Vector vector2);
public static System.Windows.Vector operator -(System.Windows.Vector vector1, System.Windows.Vector vector2);
static member ( - ) : System.Windows.Vector * System.Windows.Vector -> System.Windows.Vector
Public Shared Operator - (vector1 As Vector, vector2 As Vector) As Vector

參數

vector1
Vector

從中減去向 vector2 量。

vector2
Vector

從 中減 vector1去的向量。

傳回

Vector

與vector1的差異vector2。

範例

以下範例說明如何使用此運算子（-）從結構Vector中減去結構Vector。

private Vector overloadedSubtractionOperatorExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);

    // Subtract vector2 from vector1 using the overloaded
    // "-" operator.
    // vector Result is equal to (-25, -40).
    Vector vectorResult = vector1 - vector2;

    return vectorResult;
}

Private Function overloadedSubtractionOperatorExample() As Vector
    Dim vector1 As New Vector(20, 30)
    Dim vector2 As New Vector(45, 70)

    ' Subtract vector2 from vector1 using the overloaded
    ' "-" operator.
    ' vector Result is equal to (-25, -40).
    Dim vectorResult As Vector = vector1 - vector2

    Return vectorResult

End Function
