你忘了告訴我們_what_錯誤時拋出。運行時值是什麼時候拋出的。 – David 2012-07-10 10:06:25
當我用某個用戶名,密碼登錄時,它在第8行出現throwsx錯誤。 – NoviceToDotNet 2012-07-10 10:07:37
錯誤非常明顯,「對象引用未設置爲對象的實例」。由於它發生在第98行,因此'_userDetails'或'Rows'都是'null'。我的猜測是'_userDetails'是'null'。在這種情況下,您的'Data.GetSQLQueryResults()'方法被破壞,因爲返回'null'是一個壞主意。無論哪種方式,這不是你的問題所在。您需要修復該功能(可能還有很多其他代碼)來報告遇到的問題,以便確定哪些問題。 – David 2012-07-10 10:10:07
