Sottrae una struttura Point4D da una struttura Point4D e restituisce il risultato sotto forma di struttura Point4D.

public:
 static System::Windows::Media::Media3D::Point4D operator -(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);

public static System.Windows.Media.Media3D.Point4D operator - (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);

static member ( - ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> System.Windows.Media.Media3D.Point4D

Public Shared Operator - (point1 As Point4D, point2 As Point4D) As Point4D

Parametri

point1: Point4D

Struttura Point4D dalla quale eseguire la sottrazione.

point2: Point4D

Struttura Point4D che deve essere sottratta da point1.

Restituisce

Point4D

Restituisce la differenza tra point1 e point2.

Esempio

Nell'esempio seguente viene illustrato come utilizzare l'operatore di sottrazione di overload per sottrarre una Point4D struttura da una Point4D struttura.

// Subtracts a Point4D from a Point4D using the overloaded - operator.
// Returns a Point4D.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Point4D pointResult = new Point4D();

pointResult = point1 - point2;
// pointResult is equal to (-5, -35, -59, -71) 

// Displaying Results
syntaxString = "pointResult = point1 - point2;";
resultType = "Point4D";
operationString = "Subtracting a Vector3D from a Point4D";
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString);

' Subtracts a Point4D from a Point4D using the overloaded - operator.
' Returns a Point4D.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim pointResult As New Point4D()

pointResult = point1 - point2
' pointResult is equal to (-5, -35, -59, -71) 

' Displaying Results
syntaxString = "pointResult = point1 - point2"
resultType = "Point4D"
operationString = "Subtracting a Vector3D from a Point4D"
ShowResults(pointResult.ToString(), syntaxString, resultType, operationString)
