不会，但是，用于托管空间的话，要注意一点：对于每一个写操作，必须显式使用Gateway.BeginTransaction
()方式的事务，并在传递tran参数，否则会报msdtc服务未开启错误。

例如，Save操作必须象下面这样执行：

DbTransaction tran = Gateway.BeginTransaction();
try
{
  gateway.Save(entityObj, tran);

  tran.Commit();

}

catch
{
  tran.Rollback();
  throw;
}

finally
{
  gateway.CloseTransaction(tran);

}

那请问，我没有用到数据库写操作，所以我也没有调用事务，怎么还要报dtc未开启的错误呢，最后我开了dtc后才ok了

to 辉郎:

如果报msdtc错误，那么你肯定用到写操作了。可能你没有留意。因为，不用写操作，不会触发对TransactionScope的调用的，也就不可能报这个错 误。

using (DbTransaction tran = gateway.BeginTransaction())
            {
                .......
            }

这样是否效果也等同于gateway.CloseTransaction(tran); 呢？

不使用try catch
finally就不能保证在finally中Close这个Transaction，tran不close它关联的connection也就不会close，它 的资源就会一直被占用。
