Vector.UnaryNegation(Vector) 操作员

定义

对指定向量求反。Negates the specified vector.

public:
 static System::Windows::Vector operator -(System::Windows::Vector vector);
public static System.Windows.Vector operator - (System.Windows.Vector vector);
static member ( ~- ) : System.Windows.Vector -> System.Windows.Vector

参数

vector
Vector

要求反的向量。The vector to negate.

返回

一个向量,其 XY 值与 vectorXY 值相反。A vector with X and Y values opposite of the X and Y values of vector.

示例

下面的示例演示如何使用此否定运算符来否定Vector结构。The following example shows how to use this negation operator to negate a Vector structure.

private Vector overloadedNegationOperatorExample()
{
    Vector vector1 = new Vector(20, 30);

    // Negate vector1 with the overloaded negation operator.
    // vectorResult is equal to (-20, -30).
    Vector vectorResult = -vector1;

    return vectorResult;

}
Private Function overloadedNegationOperatorExample() As Vector
    Dim vector1 As New Vector(20, 30)

    ' Negate vector1 with the overloaded negation operator.
    ' vectorResult is equal to (-20, -30).
    Dim vectorResult As Vector = -vector1

    Return vectorResult

End Function
