範例

以下範例展示了如何使用此否定算子來否定結構 Vector 。

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
