AutoMapper使用中的问题

指定值只会执行一次

 

  public class MomanBaseProfile : Profile
    {
        public MomanBaseProfile()
        {
            CreateMap()
                .ForMember(d => d.ID, op => op.Ignore())
                .ForMember(d => d.UID, op => op.UseValue(Guid.NewGuid()))//使用Mapper过程中始终不变
                .ForMember(d => d.CreateTime, op => op.UseValue(DateTime.UtcNow))
                .ForMember(d => d.UpdateTime, op => op.UseValue(DateTime.UtcNow));

            CreateMap()
                .IncludeBase();
        }
    }

 

继承类如何减少Map问题解决

public class MomanBaseProfile : Profile
    {
        public MomanBaseProfile()
        {
            CreateMap()
                .ForMember(d => d.ID, op => op.Ignore())
                .ForMember(d => d.UID, x => x.MapFrom(ax => Guid.NewGuid()))
                .ForMember(d => d.CreateTime, x => x.MapFrom(ax => DateTime.UtcNow))
                .ForMember(d => d.UpdateTime, x => x.MapFrom(ax => DateTime.UtcNow));

           //继承类两种方式，一种使用IncludeBase（从父类映射继承）如下，另一中使用Include（从子类映射继承）
            CreateMap()
                .IncludeBase();
        }
    }
