自动映射将枚举的集合映射到视图模型集合中

Question

• AutoMapper 5.3.0 alpha（尚未升级到最新最好）

我有一个DTO如下：

public class AoACrudFieldValuesGdataHealthInput
{
    public AoACrudFieldValuesGdataHealthInput()
    {
       PrevHealthAssessment = new HashSet<HealthPrevHealthAssessmentEnum>();
    }

    public HashSet<HealthPrevHealthAssessmentEnum> PrevHealthAssessment { get; set; }
}

和EF POCO：

[Table("Health", Schema = "gdata")]
public class GdataHealthTableModel : AuditedEntity
{
    public GdataHealthTableModel()
    {
        //PrevHealthAssessment = new HashSet<HealthPrevHealthAssessmentEnum>();
    }

    [ForeignKey("Id")]
    public ICollection<GdataHealthPrevAssesmentTableModel> PrevHealthAssessment { get; set; }
}

和：

[Table("HealthPrevAssesment", Schema = "gdata")]
public class GdataHealthPrevAssesmentTableModel : AuditedEntity
{
    public HealthPrevHealthAssessmentEnum Assessment { get; set; }
}

我需要帮助扩展我的地图：

CreateMap<AoACrudFieldValuesGdataHealthInput, GdataHealthTableModel>();

这样AoACrudFieldValuesGdataHealthInput.PrevHealthAssessment最终会在GdataHealthTableModel.PrevHealthAssessment中结束。 目前我收到一个错误，因为我的CreateMap（）不够详细 - 当然。

这可能吗？ 或者我是否让映射器忽略该字段并手动完成？

注意：对于两个EF POCO，我省略了Id字段，为了简洁起见，这是一个自动增量。

Answer 1

为HealthPrevHealthAssessmentEnum - > GdataHealthPrevAssesmentTableModel定义其他地图：

CreateMap<AoACrudFieldValuesGdataHealthInput, GdataHealthTableModel>()
    .ForMember(dest => dest.PrevHealthAssessment, o => o.MapFrom(src => src.PrevHealthAssessment));

CreateMap<HealthPrevHealthAssessmentEnum, GdataHealthPrevAssesmentTableModel>()
    .ForMember(dest => dest.Id, o => o.Ignore()) // auto ID
    .ForMember(dest => dest.Assessment , o => o.MapFrom(src => src));

不确定AutoMapper可以将ICollection转换为开箱即用的HashSet，我认为可以。
