自动映射器从数据集列映射到对象列表

Question

我有一个包含 3 个固定列和其他变量的数据集，该数据集是通过存储过程在 C# 中创建的。

我想通过 Automapper 将数据集映射到此对象：

public class PrivacyStatusData
{
    public int Id { get; set; }
    public string Name{ get; set; }
    public string Surname { get; set; }
    public List<ConsentData> ConsentList { get; set; }
}

public class ConsentData
{
    public string ConsentName { get; set; } // Consent1 Column Name
    public bool ConsentValue { get; set; } // Consent1 Value
    public DateTime ConsentDate { get; set; } // Consent1Date Value
}

感谢您的帮助。

我自己找到了解决方案。静态属性通过 MapFrom 函数映射，动态属性通过自定义解析器映射。诀窍是映射 DataRow 而不是 DataTable。

CreateMap 定义：

    CreateMap<DataRow, PrivacyStatusData>()
        .ForMember(dest => dest.Id, orig => orig.MapFrom(row => (int)row["Id"]))
        .ForMember(dest => dest.Name, orig => orig.MapFrom(row => row["Name"].ToString()))
        .ForMember(dest => dest.Surname, orig => orig.MapFrom(row => row["Surname"].ToString()))
        .ForMember(dest => dest.ConsentList, orig => orig.MapFrom<DataRowToConsentDataResolver>());

解析器：

public class DataRowToConsentDataResolver : IValueResolver<DataRow, PrivacyStatusData, List<ConsentData>>
{
    public List<ConsentData> Resolve(DataRow source, PrivacyStatusData destination, List<ConsentData> destMember, ResolutionContext context)
    {
        var consentDataList = new List<ConsentData>();

        for (int i = 9; i < source.Table.Columns.Count; i += 2)
        {
            var consentData = new ConsentData();
            var consentName = source.Table.Columns[i].ColumnName.Replace("Consenso", "");
            consentName = consentName.First().ToString().ToUpper() + consentName.Substring(1).ToLower();
            consentData.ConsentName = consentName;

            if (source[i].ToString() == "1")
                consentData.ConsentValue = true;

            consentData.ConsentDate = "-";
            var dtDate = new DateTime();
            if (DateTime.TryParse(source[i + 1].ToString(), out dtDate))
                consentData.ConsentDate = dtDate.ToString("dd MMMM yyyy");

            consentDataList.Add(consentData);
        }

        return consentDataList;
    }
}

来电者：

   private List<PrivacyStatusData> MapDataTableToPrivacyStatusData(DataTable privacyData)
   {
        var rows = new List<DataRow>(privacyData.Rows.OfType<DataRow>());
        var privacyStatusDataList = mapper.Map<List<DataRow>, List<PrivacyStatusData>>(rows);

        return privacyStatusDataList;
   }
