与NHibernate拦截器和DynamicProxy混合在边表数据中

var someEvent = session.CreateCriteria<Event>().SetMaxResults(1).UniqueResult<IEvent>();
Console.WriteLine(someEvent.Title);

class Event : IEventEntity {
   //ID and props here
   public IList Translations {get; set;}
}

IEvenEntity

EventTranslation

IEventTranslation

class EventMap : ClassMap<Event>{
  //obvious ID and properties stuff here...
  HasMany<EventTranslation>(x => x.Translations);
}

public interface IEvent : IEventEntity, IEventTranslation{}

public class EventInterceptor : NHibernate.EmptyInterceptor
{
    private readonly static ProxyGenerator gen = new ProxyGenerator();

    public override object Instantiate(string clazz, NHibernate.EntityMode entityMode, object id)
    {
           var mixin = gen.CreateClassProxy(typeof(object), new[] { typeof(IEvent) }, new DynInterceptor());
                    //would also need to set the identifier here
            return mixin;
    }
}
