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

Parametry

point1

Point3D

Struktura Point3D , pro kterou se má provést odčítání.

point2

Point3D

Struktura Point3D , která se má odečíst od point1.

Návraty

Vector3D

Struktura Vector3D , která představuje rozdíl mezi point1 a point2.

Příklady

Následující příklad ukazuje, jak použít operátor přetížených odčítání k odečtení Point3D struktury ze Point3D struktury.

// 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;";
