我已经开始实施这个;
Automapper, mapping to a complex object但我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))
;
现在我想在主要地图中使用上述映射;
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?
修改
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; }
答案 0 :(得分:0)
正如评论中所提到的,初始映射应该更像是:
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));
现在说你有以下内容:
public class Source
{
public Store Store { get; set; }
}
public class Destination
{
public CSVStore Store { get; set; }
}
然后,以下映射就足够了(因为您已经将嵌套映射Store
定义为CSVStore
):
Mapper.CreateMap<Source, Destination>();
但如果Destination
更像是这样:
public class Destination
{
public CSVStore CSVStore { get; set; }
}
然后,您需要明确定义要映射的属性:
Mapper.CreateMap<Source, Destination>()
.ForMember(dest => dest.CSVStore, opt => opt.MapFrom(src => src.Store));
(请注意,Store
到CVStore
的映射会自动应用。)
如果出于某种原因需要明确定义嵌套映射,可以执行以下操作:
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,但不经常使用,因为默认功能会自动为您处理。
如果您可以扩展您的要求,我可以提供更多详细信息。
