EF 框加。。model 为短信内容，，list为短信与产品相关信息列表，想。先添加model, 然后遍历list 添加关联信息。问题是。怎样得到model.id 短信 (为自动编号ID)

Answer 1

using (TransactionScope scope = new TransactionScope())
  {
  using (var objContext = GetContext())
  {
  objContext.SMS.Add(model);
 objContext.SaveChanges();
  foreach (Product_SMS m in list)
  {
  //m.SmsID = model.ID;这里获取不到ID
  objContext.Product_SMS.Add(m);
  }  objContext.SaveChanges();
  }
  scope.Complete();
  }
这里加一句，这东西不实际入库是是无法获取滴，反正你前面是事务保证，也不怕错误
