如何在以編程方式添加Memebres後更新Marketing列表CRM 2011

Question

我創建了一個將成員插入Marketing列表的工作流程。但該過程完成時，我注意到，市場營銷列表成員櫃檯總是= N -1

       } 
       else if (!Inserimento.Get(executionContext) && _action) 
       {

        RemoveMemberListRequest RemoveMemberRequest = new RemoveMemberListRequest();

        RemoveMemberListResponse RemoveMemberResponse = service.Execute(RemoveMemberRequest) as RemoveMemberListResponse; 
        log.addLogs(ref _logs, "Remove from marketing List - Fine"); 

       } 
       else 
       { 
        log.addLogs(ref _logs, Inserimento.Get(executionContext) == true ? "L'utente è già presente nella Lista di Marketing." + _separatore : "L'utente non è presente nella Lista di Marketing." + _separatore); 
       } 

       log.WriteLog(_logs); 
       var MyList = (from l in datacontext.ListSet where l.Id == listId.Id select l).ToList().FirstOrDefault(); 
       service.Update(MyList); 

      } 
      catch(Exception ex) 
      { 
       if (log == null)    
        new Log_Entity(service).WriteLog(_logs, ex.Message); 
       else     
        log.WriteLog(_logs, ex.Message);    
      } 

     } 

    } 
} 

在我的日誌，我每次打電話Service.Update（時間），我發現消息：

EntityState必須設置爲null，創建（在創建消息）或更改（更新消息）
