Question

当我使用NHibernate来更新或保存（插入）实体时，我发现代码（session.Flush（））没有工作且没有错误信息，程序在那里结束（不是故障，功能在那里结束）。但我成功使用它插入实体，我没有修改任何代码。我很困惑，请帮助我。代码在那里：

ISession session = SessionBuilder.SessionFactory.OpenSession();

        switch (editType)
        {
            case 'S': {
                    try
                    {
                        //new info set default;
                        cs.ID = 132;
                        clc.ID = cs.ID;
                        cmc.ID = cs.ID;
                        cs.COEFFICIENT_ID = 0;
                        cs.IF_ASSOCIATION = 'N';
                        cs.COST_PRICE = 0.0f;

                        session.Save(cs);
                        session.Save(clc);
                        session.Save(cmc);
                        session.Flush();//<<--if i set a breakpoint in there,
                          //and next step the whole function will end,no catch no finally
                          //no return,the application seem never run this function.
                          //and the application continues to run normal.

                        flg = true;
                    }catch (Exception e)
                    {
                        flg = false;
                        throw e;
                    }
                    finally
                    {
                        session.Close();
                    }
                    break;
                }
            case 'E': {
                    try
                    {
                        session.Update(cs);
                        session.Update(clc);
                        session.Update(cmc);
                        session.Flush();//<<--if i set a breakpoint in there,
                          //and next step the whole function will end,no catch no finally
                          //no return,the application seem never run this function.
                          //and the application continues to run normal.
                        flg = true;
                    }catch(Exception e)
                    {
                        flg = false;
                        throw e;
                    }
                    finally
                    {
                        session.Close();
                    }

                    break; }
            default: { return false; }
        }
        return flg;
    }

Answer 1

而不是Session.Flush（）尝试使用事务：

using (var transaction = session.BeginTransaction())
{
    transaction.Commit();
}

Answer 2

嗯，问题是某些字符串超出了数据库类型的限制长度。但是，我很困惑为什么VS无法捕捉错误并且似乎从未发生过？

NHibernate session.Flush（）没有工作，也没有错误报告
