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]
