我把原码贴上, 我传了一组session到这个页用的是session[j+"reset"]表示的j是数字变量,session["reset"]是session的个数 ,我加断点发现到反斜杠中的那句话就跳到catch{}了,谢谢了.    
 try
        {
            //获得零部件的ＩＤ
            string strcomputerID = (string)Session["computer_id"];
            //连接数据库 
            DB db = new DB(this.Page.Application);
            string strSelect;
            strSelect = "select type.type_name,part.component_id,part.list_id,part.buy_price,part.note,type.only_flag from brogame_components part left join brogame_components_type type on part.type_id=type.type_id where 1=1 and part.user_flag=0 and part.delete_flag=0";
            strSelect = strSelect + " order by type.type_name";
            DataTable dTable = db.Select(strSelect, "brogame_components");
            for (int i = 0; i < dTable.Rows.Count; i++)
