Vector3D.UnaryNegation(Vector3D) 運算子

定義

命名空間:

System.Windows.Media.Media3D

組件:

PresentationCore.dll

將 Vector3D 結構加上負號。

public:
 static System::Windows::Media::Media3D::Vector3D operator -(System::Windows::Media::Media3D::Vector3D vector);

public static System.Windows.Media.Media3D.Vector3D operator - (System.Windows.Media.Media3D.Vector3D vector);

static member ( ~- ) : System.Windows.Media.Media3D.Vector3D -> System.Windows.Media.Media3D.Vector3D

Public Shared Operator - (vector As Vector3D) As Vector3D

參數

vector

Vector3D

要加上負號的 Vector3D 結構。

傳回

Vector3D

Vector3D 結構，其 X、Y 和 Z 值與 vector 的 X、Y 和 Z 值正負號相反。

範例

下列範例示範如何使用多載負運算子來否定 Vector3D 結構。

// Negates a Vector3D using the overloaded unary negation operator.

Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vectorResult = new Vector3D();

vectorResult = -vector1;
// vectorResult is equal to (-20, -30, -40)

' Negates a Vector3D using the overloaded unary negation operator.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vectorResult As New Vector3D()

vectorResult = -vector1
' vectorResult is equal to (-20, -30, -40)

備註

傳回 Vector3D 的結構的大小與 () Lengthvector 相同，但其方向與 的 vector 相反。
