AutoMapper異常

Question

這是我第一次陷入這樣由automapper。我試圖將存儲過程返回的結果集映射到我的實體。 L2S的結果集可用，它是我當前測試的一行，可以是多個。如果處理不當，返回類型爲空時通常會引發automaper異常。我已經離開了它，也改變了一些價值，但在這兩種情況下，我仍然得到例外。我錯過了一些非常基本的東西，但不能把它放在手上。需要第二雙眼睛......謝謝。

代碼調用

var annualReportOutreachEditionResult = ClientsContext.AnnualReportOutreachEditionInfoGet(fice, reportYear).ToList(); 
      if (annualReportOutreachEditionResult != null) 
      { 
       annualReportOutreachEditionDetail = Mapper.Map<List<AnnualReportOutreachEditionInfoGetResult>, List<AnnualReportOutreachEditionDetail>>(annualReportOutreachEditionResult); 

AnnualReportOutreachEditionDetail實體

public class AnnualReportOutreachEditionDetail 
    { 



     public string Edition { get; set; } 


     public DateTime MailDate { get; set; } 


     public string CardId { get; set; } 


    } 

AnnualReportOutreachEditionInfoGetResult L2S實體

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; 
       } 
      } 
     } 
    } 

準備

我也檢查/測試defaultvalue的日期和我的例外仍然存在。這是唯一可以爲空的類型。

public static void MapAnnualReportOutreachEditionDetail() 
     { 
      Mapper.CreateMap<AnnualReportOutreachEditionInfoGetResult, AnnualReportOutreachEditionDetail>() 

       ; 
     }

這是在我這邊出了問題，我忘了補充定義爲我的映射器的方法。固定。
