[英]Automapper base class mapping
For AutoMapper, I've implemented the following which works, but has repeated mapping code: 对于AutoMapper,我实现了以下可行的方法,但是重复了映射代码:
cfg.CreateMap<RmsOelEntryUnlinkedPersonInputDto, AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked>()
.ForMember(dest => dest.DateOfBirth, opts => opts.MapFrom(src => FormatDateType(src.DateOfBirth)))
.ForMember(dest => dest.EffectiveFromTime, opts => opts.MapFrom(src => FormatDateTimeType(src.EffectiveFromTime)))
.ForMember(dest => dest.EffectiveToTime, opts => opts.MapFrom(src => FormatDateTimeType(src.EffectiveToTime)));
cfg.CreateMap<RmsOelEntryUnlinkedAddressInputDto, AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked>()
.ForMember(dest => dest.EffectiveFromTime, opts => opts.MapFrom(src => FormatDateTimeType(src.EffectiveFromTime)))
.ForMember(dest => dest.EffectiveToTime, opts => opts.MapFrom(src => FormatDateTimeType(src.EffectiveToTime)));
Both RmsOelEntryUnlinkedPersonInputDto
and RmsOelEntryUnlinkedAddressInputDto
are inherited from RmsOelEntryInvolvedEntityBaseDto
and this base class has the properties EffectiveFromTime
and EffectiveToTime
. RmsOelEntryUnlinkedPersonInputDto
和RmsOelEntryUnlinkedAddressInputDto
均从RmsOelEntryInvolvedEntityBaseDto
继承,并且此基类具有EffectiveFromTime
和EffectiveToTime
属性。
I don't want the to have to repeatedly map EffectiveFromTime
and EffectiveToTime
as seen above. 我不希望必须如上所述反复映射
EffectiveFromTime
和EffectiveToTime
。
However, AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked
and AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked
are autogenerated and don't have a base class. 但是,
AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked
和AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked
是自动生成的,没有基类。 Therefore I don't see how I can use AutoMapper's "Include" mapping option. 因此,我看不到如何使用AutoMapper的“包含”映射选项。
How do I optimise this to remove the repeated mapping? 如何优化此设置以删除重复的映射?
I had similar situation and have resorted to helper Extension methods. 我有类似的情况,并求助于辅助扩展方法。 I customized for your case :
我为您量身定做:
internal static class CommonMapperExtensions
{
internal static IMappingExpression<TSource, TDestination> MapCommonFields<TSource, TDestination>(this IMappingExpression<TSource, TDestination> m)
where TSource : RmsOelEntryInvolvedEntityBaseDto
where TDestination : IEffective
{
return m
.ForMember(dest => dest.EffectiveFromTime, opts => opts.MapFrom(src => FormatDateTimeType(src.EffectiveFromTime)))
.ForMember(dest => dest.EffectiveToTime, opts => opts.MapFrom(src => FormatDateTimeType(src.EffectiveToTime)));
}
}
Then configuration would look like this : 然后配置如下所示:
cfg.CreateMap<RmsOelEntryUnlinkedPersonInputDto, AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked>()
.MapCommonFields()
.ForMember(dest => dest.DateOfBirth, opts => opts.MapFrom(src => FormatDateType(src.DateOfBirth)));
cfg.CreateMap<RmsOelEntryUnlinkedAddressInputDto, AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked>()
.MapCommonFields();
If AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked
and AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked
are autogenerated I would assume they are partial. 如果自动生成
AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked
和AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked
是自动生成的,那么我认为它们是局部的。
Then you could make common interface for those classes : 然后,您可以为这些类创建通用接口:
public interface IEffective
{
DateTime EffectiveFromTime {get; set;}
DateTime EffectiveToTime {get; set;}
}
public partial AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedAddressUnlinked
: IEffective { }
public partial AddNewOELEntryInvolvedEntitiesUnlinkedInvolvedPersonUnlinked
: IEffective { }
public class TBaseModel
{
public void ConfigureMapFrom(IMappingExpression<TEntity, TBaseModel> mapping)
{
// ... mappings
}
}
public class TModel : TBaseModel
{
public void ConfigureMapFrom(IMappingExpression<TEntity, TModel> mapping)
{
mapping.IncludeBase<TEntity, TBaseModel>();
// ... other mappings
}
}
