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 Function ReturnVehicle(i As Integer) As Vehicle
        
        If i = 0 Then
