要求反的向量。
一个向量，其 X 和 Y 值与 vector 的 X 和 Y 值相反。
以下示例演示如何使用此求反运算符来否定 Vector 结构。
C#
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
