Automapper Mapping, inheritance from generic list

问题

    public class Flight {
        public CabinCollection Cabins { get; set; }
    }

    public class CabinCollection : List<Cabin>
    {
        public Cabin Lowest { set; get; }
    }

source and dest class have the same members

   1)  Mapper.Initialize(cfg => {
        cfg.CreateMap<Domain.Flight, Contract.Flight>();
        cfg.CreateMap<Domain.Cabin, Contract.Cabin>();
    });

    List<Flight> res = Mapper.Map<List<Flight>>(flights);

It works but the member 'lowest' is null

   2)  Mapper.Initialize(cfg => {
            cfg.CreateMap<Domain.Flight, Contract.Flight>();
            cfg.CreateMap<Domain.Cabin, Contract.Cabin>();
            cfg.CreateMap<Domain.CabinCollection,Contract.CabinColection>
                .IncludeBase<List<Domain.Cabin>, List<Contract.Cabin>>()
        });

It works and the member 'lowest' mapped, but the list is null

Is there a way make it right?

回答1:

Add this to your configuration

cfg.CreateMap<Domain.CabinCollection, Contract.CabinCollectionDest>();

Basically Automapper wouldn't know how to map CabinCollection object

.Net fiddle link to show this
