[英]Mapping nested lists with automapper
This is my class setup. 这是我的课程设置。 How do i map only Invalid=false for DTOReportObservation AND DTOReportObservationLocation items?
如何仅将Invalid = false映射到DTOReportObservation和DTOReportObservationLocation项目?
reports = Mapper.Map<List<Report>, List<DTOReport>>(userReports);
public class DTOReport
{
public List<DTOReportObservation> Observations;
}
public class DTOReportObservation
{
public Guid ReportObservationID { get; set; }
public Guid ReportID { get; set; }
public bool Invalid { get; set; }
public List<DTOReportObservationLocation> ObservationLocations;
}
public class DTOReportObservationLocation
{
public Guid ReportObservationLocationID { get; set; }
public Guid ReportObservationID { get; set; }
public bool Invalid { get; set; }
}
CreateMap<Report, DTOReport>(MemberList.Source)
.ForMember(d => d.Observations, opt => opt.MapFrom(src => src.ReportObservations))
//??ReportObservations.Locations
With automapper you shouldn't need to create maps of lists. 使用自动映射器,您无需创建列表映射。 You just create a map from one type to another and let automapper iterate over the collections.
您只需创建从一种类型到另一种类型的映射,然后让自动映射器遍历集合。
Can you also clarify what you mean by Invalid=false seeing as Invalid is a guid type. 您是否还可以澄清一下Invalid = false的含义,因为Invalid是一种GUID类型。
For mapping only when invalid is false you can use the conditional mapping. 对于仅当invalid为false时的映射,您可以使用条件映射。 https://automapper.readthedocs.io/en/latest/Conditional-mapping.html .
