瓦尔扎，

尝试通过try catch块来处理它.如果数据库中出现任何错误，它将捕获在catch块中.要仅插入正确的数据，可以在代码级别使用验证.

Hi Valza,

Try to handle it through try catch block.If any error come through database then it will catch in catch block. To insert only correct data you can use validation at code level.

您需要使用 System.Data.Linq.ChangeSet changes = db.GetChangeSet( ); 在db.SubmitChanges();之前；获取更改数量.

You need to use System.Data.Linq.ChangeSet changes = db.GetChangeSet(); before db.SubmitChanges(); to get the number of changes.
