Public Shared Operator - (point1 As Point3D, point2 As Point3D) As Vector3D

Параметры

point1

Point3D

Структура Point3D, на которой выполняется вычитание.

point2

Point3D

Структура Point3D, вычитаемая из point1.

Возвращаемое значение

Vector3D

Структура Vector3D, представляющая разность между point1 и point2.

Примеры

В следующем примере показано, как использовать перегруженный оператор вычитания для вычитания Point3D структуры из Point3D структуры.

// 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.
