如何通过BaseType获取Mapper

Question

我想通过使用基本类型获得注释映射器(AutoMapper.Mapper.FindTypeMapFor)。

是否可以像用法中那样获取

        AutoMapper.Mapper.CreateMap<IEntity, ListItemModelBase>()
            .Include<Book, BookListItemModel>();

        AutoMapper.Mapper.CreateMap<Book, BookListItemModel>()              
            .ForMember(  a => a.Author, (a) => a.MapFrom( entity => entity.Author.Name))
            .ForMember(a => a.Genre, (a) => a.MapFrom( entity => entity.Genre.Name));


        AutoMapper.Mapper.CreateMap<BookListItemModel, Book>();

        AutoMapper.Mapper.CreateMap<BookFormModel, Book>()
            .ForMember(a => a.Id, (model) => model.PreCondition((context) => context.Id > 0))
            .ForMember( a => a.UpdateDate, (model) => model.PreCondition((context) => context.Id > 0))
            .ForMember( a => a.InsertDate, (model) => model.PreCondition((context) => context.Id == 0));

        AutoMapper.Mapper.CreateMap<Book, BookFormModel>();

var mapper = AutoMapper.Mapper.FindTypeMapFor<IEntity, ListItemModelBase>();
//var mapper = AutoMapper.Mapper.FindTypeMapFor<Book, BookListItemModel>();
mapper.Dump();
mapper.GetPropertyMaps().Dump();

我想到的解决方案

var mapper = AutoMapper.Mapper
     .GetAllTypeMaps()
     .Where(a => a.SourceType == typeof(Book) && typeof(ListItemModelBase).IsAssignableFrom(a.DestinationType)                                        && !a.DestinationType.IsAbstract)
     .FirstOrDefault()
