C# 当表存在时，无法加载NHibernate中的实体，然后超时异常

我需要帮助

我在插入/更新许多记录时遇到此错误

could not load an entity: 
[Star.CNPL_BusinessObjects.Entities.CNPL.CNPL_AgencyProduct#48][SQL: SELECT cnpl_agenc0_.Id as Id48_0_, cnpl_agenc0_.AgencyID as AgencyID48_0_, cnpl_agenc0_.ProductID as ProductID48_0_, cnpl_agenc0_.CreatedDate as CreatedD4_48_0_, cnpl_agenc0_.CreatedBy as CreatedBy48_0_, cnpl_agenc0_.UpdatedDate as UpdatedD6_48_0_, cnpl_agenc0_.UpdatedBy as UpdatedBy48_0_ FROM CNPL_AgencyProduct cnpl_agenc0_ WHERE cnpl_agenc0_.Id=?]"

然后，我得到了这个内部异常

这家伙需要帮助。想法会有帮助。：）

我们找到了解决这个问题的办法

当NHibernate从更新变为插入时，它似乎经历了一段艰难的时期。问题是，当批量事务中的更新之前有插入时，就会发生此错误。我们所做的是将更新和插入事务分开，这样就可以工作了

我想知道这是否是因为NHibernate dll。对此有何想法？

在执行nhiberbate之前，尝试添加以下语句：例如：

if (_session.Connection.State == System.Data.ConnectionState.Open)
                {
                    _session.Connection.Close();
                    _session.Connection.Open();
                }
                else if (_session.Connection.State == System.Data.ConnectionState.Closed)
                {                    
                    _session.Connection.Open();
                }

result = _session.CreateCriteria<T>().List<T>();

if（_session.Connection.State==System.Data.ConnectionState.Open）
{
_session.Connection.Close（）；
_session.Connection.Open（）；
}
else if（_session.Connection.State==System.Data.ConnectionState.Closed）
{                    
_session.Connection.Open（）；
}
结果=_session.CreateCriteria（）.List（）；
