public static System.Windows.Media.Media3D.Vector3D operator - (System.Windows.Media.Media3D.Vector3D vector1, System.Windows.Media.Media3D.Vector3D vector2);

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

Public Shared Operator - (vector1 As Vector3D, vector2 As Vector3D) As Vector3D

參數

vector1

Vector3D

要減去其中內容的 Vector3D 結構。

vector2

Vector3D

要從 vector1 中減去的 Vector3D 結構。

傳回

Vector3D

vector2 減去 vector1 的結果。

範例

下列範例示範如何使用多載減法運算子，從 Vector3D 結構中減去 Vector3D 結構。

// Subtracts a Vector3D from a Vector3D using the overloaded - operator.  
// Returns a Vector3D.

Vector3D vector1 = new Vector3D(20, 30, 40);
Vector3D vector2 = new Vector3D(45, 70, 80);
Vector3D vectorResult = new Vector3D();

vectorResult = vector1 - vector2;
// vector Result is equal to (-25, -40, -40)

' Subtracts a Vector3D from a Vector3D using the overloaded - operator.  
' Returns a Vector3D.

Dim vector1 As New Vector3D(20, 30, 40)
Dim vector2 As New Vector3D(45, 70, 80)
Dim vectorResult As New Vector3D()

vectorResult = vector1 - vector2
' vector Result is equal to (-25, -40, -40)
