AutoMapper用法

可在每层这样写一个类，整合每个实体类的映射

public  class AutoMapperHelper
    {
       public static void Register()
       {
           Mapper.Initialize(x => x.AddProfile<ModelProfile>());

       }

    }

   public class ModelProfile : Profile
   {
       public override string ProfileName
       {
           get
           {
               return GetType().Name;
           }
       }

       protected override void Configure()
       {

           CreateMap<AccessoryDto, i_accessory>()
              .ForMember(d => d.CategoryID, opt => opt.MapFrom(s => s.CategoryL2ID));

       }
   }

然后在使用中先调用一下，注册映射关系类

AutoMapperHelper.Register();
