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

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

Parametri

vector1

Vector3D

Struttura Vector3D dalla quale eseguire la sottrazione.

vector2

Vector3D

Struttura Vector3D che deve essere sottratta da vector1.

Restituisce

Vector3D

Risultato della sottrazione di vector2 da vector1.

Esempio

Nell'esempio seguente viene illustrato come usare l'operatore di sottrazione di overload per sottrarre una Vector3D struttura da una Vector3D struttura.

// 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)
