Exemples

L’exemple suivant montre comment utiliser l’opérateur de soustraction surchargé pour soustraire une Point3D structure d’une 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);
