Vector3D.UnaryNegation(Vector3D) 運算子

定義

Vector3D 結構加上負號。Negates a Vector3D structure.

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。The Vector3D structure to negate.

傳回

Vector3D 結構,其 XYZ 值與 vectorXYZ 值正負號相反。A Vector3D structure with X, Y, and Z values opposite of the X, Y, and Z values of vector.

範例

下列範例顯示如何使用多載的負運算子來否定Vector3D結構。The following example shows how to use the overloaded negation operator to negate a Vector3D structure.

// 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的結構與具有相同的大小Length() vector , vector但其方向與的相反。The returned Vector3D structure has the same magnitude (Length) as vector but its direction is opposite of that of vector.
