遇到個棘手的問題,在功能中數據層有個方法是返回一個泛型的方法,發布后在IIS中測試,調用10多次都沒有問題,過后就出現這個問題,感覺極為不穩定,然后這個方法一直過不去,要重啟IIS才行,而在VS工具中測試從來不報錯,報錯信息如下:
異常詳細信息: System.ArgumentException: 列“Props_TypeName”不屬於表 Table。
SQL語句中Props_TypeName,Pi_SmallImg字段都是動態構建的,本身不屬於Idol_PropsPurchases這個表,我以前試過用SqlDataReader來讀取也報類似錯誤.所以
改為DataTable來操作。
public static List<Idol_PropsPurchases> GetPropsBagInfo(int BagId, int Idol_Id) { List<Idol_PropsPurchases> Lipp = new List<Idol_PropsPurchases>(); string Sql = "select (select dbo.Props_GetParentName(Pt_Id) from Props_Info where Pi_Id = Ipp.Pi_Id) as Props_TypeName,(select Pi_SmallImg from Props_Info where Pi_Id = Ipp.Pi_Id) as Pi_SmallImg,* from Idol_PropsPurchases Ipp where datediff(s,convert(varchar(20),getdate(),120),Ipp_EndTime)>0 and Ipp_IsUse = 0 and Bag_Id="+BagId+" and Idol_Id="+Idol_Id+""; SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MemberDBCS"].ConnectionString); con.Open(); SqlDataAdapter Sda = new SqlDataAdapter(Sql, con); DataSet Ds = new DataSet();//;SqlHelper.GetDataTable(Sql) Sda.Fill(Ds); DataTable Dt = Ds.Tables[0]; con.Close(); if (Dt.Rows.Count != 0) { foreach (DataRow Row in Dt.Rows) { Idol_PropsPurchases Ipp = new Idol_PropsPurchases(); Ipp.Props_TypeName = Row["Props_TypeName"].ToString(); Ipp.Pi_SmallImg = Row["Pi_SmallImg"].ToString(); Ipp.Pi_Id = int.Parse(Row["Pi_Id"].ToString()); Ipp.Ipp_AccumulationCount = int.Parse(Row["Ipp_AccumulationCount"].ToString()); Ipp.Ipp_PositionNum = int.Parse(Row["Ipp_PositionNum"].ToString()); Ipp.Ipp_IsProps = bool.Parse(Row["Ipp_IsProps"].ToString()); Lipp.Add(Ipp); } } return Lipp; }
