Automapper复杂对象
我已经开始实施这个;
Automapper映射到一个复杂的对象,但认为必须有更好的方法。
所以我创造了这个;
Mapper.CreateMap<StoreTransportWindow, CSVWindow>()
.ForMember(dest => dest.DC, opt => opt.ResolveUsing(fa => fa.DC.number))
.ForMember(dest => dest.Type, opt => opt.ResolveUsing(fa => fa.Type))
;
Mapper.CreateMap<Store, CSVStore>()
.ForMember(dest => dest.StoreName, opt => opt.ResolveUsing(fa => fa.name))
.ForMember(dest => dest.StoreNumber, opt => opt.ResolveUsing(fa => fa.number))
;
现在我想在主映射中使用上面的映射;
Mapper.CreateMap<Store, CSVLineObject>()
.ForMember( dest => dest.store, opt => opt.ResolveUsing(/* This is where I'd like to use the above Store to CSVStore mapping */))
;
这可能吗?
编辑
public class CSVStore
{
public string StoreNumber { get; set; }
public string StoreName { get; set; }
}
public class CSVWindow
{
public string Type { get; set; }
public string DC { get; set; }
public string TPC { get; set; }
public class CSVLineObject
{
public CSVStore store { get; set; }
public List<CSVWindow> storeWindows { get; set; }
正如评论中提到的,最初的映射可能应该更像:
Mapper.CreateMap<StoreTransportWindow, CSVWindow>()
.ForMember(dest => dest.DC, opt => opt.MapFrom(src => src.DC.number));
// Mapping for property Type not required
Mapper.CreateMap<Store, CSVStore>()
.ForMember(dest => dest.StoreName, opt => opt.MapFrom(src => src.name))
.ForMember(dest => dest.StoreNumber, opt => opt.MapFrom(src => src.number));
现在说你有以下几点:
public class Source
{
public Store Store { get; set; }
}
public class Destination
{
public CSVStore Store { get; set; }
}
那么下面的映射就足够了(因为你已经定义了嵌套映射Store
到CSVStore
):
Mapper.CreateMap<Source, Destination>();
但是,如果Destination
更像这样:
public class Destination
{
public CSVStore CSVStore { get; set; }
}
然后,您需要显式定义要映射的属性:
Mapper.CreateMap<Source, Destination>()
.ForMember(dest => dest.CSVStore, opt => opt.MapFrom(src => src.Store));
(请注意,从Store
到CVStore
的映射会自动应用。)
如果由于某种原因你确实需要明确定义一个嵌套映射,你可以这样做:
Mapper.CreateMap<Source, Destination>()
.ForMember(dest => dest.destproperty,
opt => opt.MapFrom(
src => Mapper.Map<SrcType, DestType>(src.srcproperty));
我有时需要使用它,但不是很经常,因为默认功能会自动为您处理。
如果您可以扩展您的需求,我可以提供更多详细信息。
