Exemples

L’exemple suivant montre trois classes, dont deux héritent du troisième. L’exemple applique la XmlIncludeAttribute méthode qui retourne une instance de l’une des deux classes dérivées. L’exemple définit la Type propriété sur le type de l’objet retourné.

public ref class Vehicle{};

public ref class Car: public Vehicle{};

public ref class Truck: public Vehicle{};

public ref class Sample
{
public:

   [WebMethodAttribute]
   [XmlInclude(Car::typeid)]
   [XmlInclude(Truck::typeid)]
   Vehicle^ ReturnVehicle( int i )
   {
      if ( i == 0 )
            return gcnew Car;
      else
            return gcnew Truck;
   }
};
public class Vehicle{}

public class Car:Vehicle{}

public class Truck:Vehicle{}

public class Sample
{
[WebMethodAttribute]
[XmlInclude(typeof(Car))]
[XmlInclude(typeof(Truck))]
public Vehicle ReturnVehicle(int i){
   if(i == 0)
      return new Car();
   else
      return new Truck();
   }
}
Public Class Vehicle
End Class
 
Public Class Car
    Inherits Vehicle
End Class
 
Public Class Truck
    Inherits Vehicle
End Class
 
Public Class Sample    
    <WebMethod(), _
     XmlInclude(GetType(Car)), _
     XmlInclude(GetType(Truck))> _
    Public Function ReturnVehicle(i As Integer) As Vehicle
        
        If i = 0 Then
            Return New Car()
