c# Automapper通用映射
本文关键字:映射 Automapper | 更新日期: 2023-09-27 18:06:57
在使用AutoMapper时,我想知道以下是否可以这样实现(还没有能够正确设置)。
基础服务:
public class BaseService<T, IEntityDTO> : IService<T, IEntityDTO> where T : class, IEntity
{
private IUnitOfWork _unitOfWork;
private IRepository<IEntity> _repository;
private IMapper _mapper;
public BaseService(IUnitOfWork unitOfWork, IMapper mapper)
{
_unitOfWork = unitOfWork;
_repository = unitOfWork.Repository<IEntity>();
_mapper = mapper;
}
public IList<IEntityDTO> GetAll()
{
return _mapper.Map<IList<IEntityDTO>>(_repository.GetAll().ToList());
}
}
具体服务:
public class HotelService : BaseService<Hotels, HotelsDTO>, IHotelService
{
private IUnitOfWork _unitOfWork;
private IRepository<Hotels> _hotelsRepository;
private IMapper _mapper;
public HotelService(IUnitOfWork unitOfWork, IMapper mapper) : base(unitOfWork, mapper)
{
_unitOfWork = unitOfWork;
_hotelsRepository = unitOfWork.Repository<Hotels>();
_mapper = mapper;
}
}
当前映射:
public class AutoMapperProfileConfiguration : Profile
{
protected override void Configure()
{
CreateMap<Hotels, HotelsDTO>().ReverseMap();
}
}
我对该如何进行映射毫无头绪。有人有什么建议吗,还是说我们不该这么做?
可以在BaseService
中指定DTO类型作为通用参数:
public class BaseService<T, TDTO> : IService<T, TDTO>
where T : class, IEntity
where TDTO : class, IEntityDTO
{
private IRepository<T> _repository;
...
...
public IList<TDTO> GetAll()
{
return _mapper.Map<IList<TDTO>>(_repository.GetAll().ToList());
}
}
设法解决了我的问题,下面的代码行查找传入实体到基本控制器的映射。
public List<TDTO> GetAll()
{
var list = _repository.GetAll().ToList();
return (List<TDTO>)_mapper.Map(list, list.GetType(), typeof(IList<TDTO>));
}
