自動映射將枚舉的集合映射到視圖模型集合中

Question

• AutoMapper 5.3.0 alpha（尚未升級到最新最好）

我有一個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; }
}

我需要幫助擴展我的地圖：

CreateMap<AoACrudFieldValuesGdataHealthInput, GdataHealthTableModel>();

這樣AoACrudFieldValuesGdataHealthInput.PrevHealthAssessment最終會在GdataHealthTableModel.PrevHealthAssessment中結束。 目前我收到一個錯誤，因為我的CreateMap（）不夠詳細 - 當然。

這可能嗎？ 或者我是否讓映射器忽略該字段並手動完成？

注意：對於兩個EF POCO，我省略了Id字段，為了簡潔起見，這是一個自動增量。

Answer 1

為HealthPrevHealthAssessmentEnum - > GdataHealthPrevAssesmentTableModel定義其他地圖：

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));

不確定AutoMapper可以將ICollection轉換為開箱即用的HashSet，我認為可以。
