自动映射器映射，从通用列表继承 [英] Automapper Mapping, inheritance from generic list

问题描述

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

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

source和dest类具有相同的成员

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);

它可以工作，但成员最低"为空

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>>()
        });

它可以工作并且成员最低"被映射，但是列表为空

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

有没有办法做到这一点?

Is there a way make it right?

推荐答案

将此添加到您的配置中

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

基本上，Automapper不知道如何映射 CabinCollection 对象

Basically Automapper wouldn't know how to map CabinCollection object
