Parametri

point1
Point3D

Struttura Point3D sulla quale eseguire la sottrazione.The Point3D structure on which to perform subtraction.

point2
Point3D

Struttura Point3D che deve essere sottratta da point1.The Point3D structure to subtract from point1.

Restituisce

Vector3D

Struttura Vector3D che rappresenta la differenza tra point1 e point2.A Vector3D structure that represents the difference between point1 and point2.

Esempio

Nell'esempio seguente viene illustrato come utilizzare l'operatore di sottrazione di overload per sottrarre una Point3D struttura a una Point3D struttura.The following example shows how to use the overloaded subtraction operator to subtract a Point3D structure from a Point3D structure.

// Subtracts a Point3D from a Point3D using the overloaded - operator.
// Returns a Vector3D.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
Vector3D vectorResult = new Vector3D();

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

// Displaying Results
syntaxString = " vectorResult = point1 - point2;";
resultType = "Vector3D";
operationString = "Subtracting a Point3D from a Point3D";
ShowResults(vectorResult.ToString(), syntaxString, resultType, operationString);

' Subtracts a Point3D from a Point3D using the overloaded - operator.
' Returns a Vector3D.

Dim point1 As New Point3D(10, 5, 1)
Dim point2 As New Point3D(15, 40, 60)
Dim vectorResult As New Vector3D()

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

' Displaying Results
syntaxString = " vectorResult = point1 - point2"
resultType = "Vector3D"
operationString = "Subtracting a Point3D from a Point3D"
ShowResults(vectorResult.ToString(), syntaxString, resultType, operationString)
