我是否正确使用了 Automapper 2.0 的 Include 功能？

要么我没有，要么它不起作用...我有一个 Source 类，我想将其映射到彼此继承的多个视图。

基本上，基类是 Detail，子类是 Edit 或 Update，它们使用与 Detail 相同的所有数据，再加上几个其他字段来管理自己的列表或其他内容。

这是我正在使用的地图：

Mapper.CreateMap<Ticket, Detail>()
                .Include<Ticket, Update>()
                .Include<Ticket, Edit>()
                .ForMember(dest => dest.Priority, opt => opt.MapFrom(src => src.Priority.Code))
                .ForMember(dest => dest.TicketID, opt => opt.MapFrom(src => src.ID))
                .ForMember(dest => dest.Status, opt => opt.MapFrom(src => src.StatusCode))
                .ForMember(dest => dest.Category, opt => opt.MapFrom(src => src.ProblemCategoryCode))
                .ForMember(dest => dest.crmBusCode, opt => opt.MapFrom(src => src.Company.crmBusCode))
                .ForMember(dest => dest.TeamMembers, opt => opt.MapFrom(src => src.Schedules.Where(s => s.CompleteTime == null)));

            Mapper.CreateMap<Ticket, Update>()
                .ForMember(m => m.Schedules, opt => opt.MapFrom(t => t.Schedules.Where(s => s.EmployeeID == Util.CurrentUserID() && s.CompleteTime == null)));

            Mapper.CreateMap<Ticket, Edit>();

然后，如果我 Mapper.Map(ticket) 任何使用 MapFrom 的属性没有得到评估，它们最终只会得到没有设置映射时所拥有的值。

那么这里出了什么问题呢？

如果您不想打电话，作为替代解决方案Mapper.Map两次。您可以移动以下公共映射Detail进入扩展方法：

public static class MappingExtensions
{
    public static IMappingExpression<Ticket, TDest> MapDetailProperties<TDest>(
         this IMappingExpression<Ticket, TDest> mapBase) where TDest : Detail
    {
        return mapBase
            .ForMember(dest => dest.Priority, 
                opt => opt.MapFrom(src => src.Priority.Code))
             ///....
            .ForMember(dest => dest.TeamMembers, 
               opt => opt.MapFrom(src => src
                   .Schedules.Where(s => s.CompleteTime == null)));
    }
}

然后在注册时使用该扩展方法Ticket -> Update and Ticket -> Edit映射器：

Mapper.CreateMap<Ticket, Update>()
    .MapDetailProperties()
    .ForMember(m => m.Schedules, opt => opt.MapFrom(t => t.Schedules
        .Where(s => s.EmployeeID == Util.CurrentUserID() && 
            s.CompleteTime == null)));

Mapper.CreateMap<Ticket, Edit>()
    .MapDetailProperties();

然后就可以正常使用Map了：

Ticket ticket = new Ticket();    
var edit = Mapper.Map<Ticket, Edit>(ticket);
var update = Mapper.Map<Ticket, Update>(ticket);
