Vector.UnaryNegation(Vector) 运算符

定义

命名空间:

System.Windows

程序集:

WindowsBase.dll

对指定向量求反。

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

Public Shared Operator - (vector As Vector) As Vector

参数

vector

Vector

要求反的向量。

返回

Vector

一个向量，其 X 和 Y 值与 vector 的 X 和 Y 值相反。

示例

以下示例演示如何使用此求反运算符来否定 Vector 结构。

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
