这是我第一次被autpper陷入困境。我试图将存储过程返回的结果集映射到我的实体。 L2S具有可用的结果集,对于我当前的测试,它是一行,可以是多个。如果没有正确处理返回类型可以为空,通常会抛出自动化异常。我已按原样离开它并将其更改为某个值,但在这两种情况下我仍然得到例外。我错过了一些非常基本的东西,但不能把它放在手上。需要第二双眼睛......谢谢。
代码电话
var annualReportOutreachEditionResult = ClientsContext.AnnualReportOutreachEditionInfoGet(fice, reportYear).ToList();
if (annualReportOutreachEditionResult != null)
{
annualReportOutreachEditionDetail = Mapper.Map<List<AnnualReportOutreachEditionInfoGetResult>, List<AnnualReportOutreachEditionDetail>>(annualReportOutreachEditionResult);
AnnualReportOutreachEditionDetail Entity
public class AnnualReportOutreachEditionDetail
{
public string Edition { get; set; }
public DateTime MailDate { get; set; }
public string CardId { get; set; }
}
AnnualReportOutreachEditionInfoGetResult L2S实体
public partial class AnnualReportOutreachEditionInfoGetResult
{
private string _Edition;
private System.Nullable<System.DateTime> _MailDate;
private string _CardId;
public AnnualReportOutreachEditionInfoGetResult()
{
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_Edition", DbType="VarChar(50)")]
public string Edition
{
get
{
return this._Edition;
}
set
{
if ((this._Edition != value))
{
this._Edition = value;
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_MailDate", DbType="Date")]
public System.Nullable<System.DateTime> MailDate
{
get
{
return this._MailDate;
}
set
{
if ((this._MailDate != value))
{
this._MailDate = value;
}
}
}
[global::System.Data.Linq.Mapping.ColumnAttribute(Storage="_CardId", DbType="Char(9)")]
public string CardId
{
get
{
return this._CardId;
}
set
{
if ((this._CardId != value))
{
this._CardId = value;
}
}
}
}
映射
我还检查/测试了defaultvalue的日期,我的异常仍在那里。这是唯一可以为空的类型。
public static void MapAnnualReportOutreachEditionDetail()
{
Mapper.CreateMap<AnnualReportOutreachEditionInfoGetResult, AnnualReportOutreachEditionDetail>()
;
}

这是我的问题,我忘了添加mapper方法的定义。固定的。
