关于WCF中间层服务器端DTO属性更新如何同步回仓储实体的处理方式

中间层建立上下文录制对象及录制属性。如下范例：

public bool CancelChangeEvent(ClientContext context, Dbs dbs, int encounterId, int transferId, int sickbedId, ref DataManagerContext dataContext)
{
  DataManager manager;
  IList<IEntityWithKey> recordedlist;

  recordedlist = new List<IEntityWithKey>() { dtos, dtoEncounter };
  manager = DataManagerFactory.Create(recordedlist);
  manager.RecordProperty<DtoTransfer>(a => a.IsTransferedOverTo);
  manager.RecordProperty<DtoMonitorEvent>(a => a.RecorderId, a => a.EventDateTime, a => a.EndOn, a => a.Description, a => a.IxsEventII, a => a.RowVersion);
  manager.RecordProperty<DtoEncounter>(a => a.StatusCodeId, a => a.SickBedOrganizationId, a => a.ResponsibleDepartmentId, a => a.IsTransferred, a => a.BabyFlag, a => a.SeqNoText, a => a.MotherEncounterId, a => a.RowVersion);
  ... ...

  manager.UpdateContext(dataContext);
  return true;
}

仓储对应的方法需要将返回的上下文应用到实体对应的DTO上（上下文已根据DTO主键建立属性键值对），范例代码如下：

public bool CancelChangeEvent(ITransfer entity, int newsickbedId)
{
  DataManagerContext dataContext = new DataManagerContext();

  using (ServiceProxy<ITransferSvc> obj = GetObject<ITransferSvc>())
  {
    DtoTransfer dto = DtoAccessor.GetFrom<DtoTransfer>(entity).GetDto();
    DtoEncounter dtoEncounter = DtoAccessor.GetFrom<DtoEncounter>(entity.Owner).GetDto();

    ret = obj.Service.CancelChangeEvent(Context, DbsKind.GetDbs(), entity.Owner.Id, entity.Id, newsickbedId, ref dataContext);
    if (ret)
    {
      DataManager dataManager = DataManagerFactory.Create(dtoEncounter);
      dataManager.ApplyContext(dataContext);
      DtoAccessor.GetFrom<DtoEncounter>(entity.Owner).SetDto(dtoEncounter);

      dataManager = DataManagerFactory.Create(dto);
18       dataManager.ApplyContext(dataContext);
    }
  }
  return true;
}
