System.Data.OleDb.OleDbException：無效的密碼。 在MS Access數據庫ASP.NET/C# Web應用程序中

Question

我陷入了令人擔憂的問題中。 使用MS Access 2007數據庫開發了一個ASP.NET/C# Web應用程序。數據庫與我開發該應用程序的服務器位於同一服務器（Windows服務器2008 R2）中。 它具有一個簡單的GridView來顯示搜索結果。 當它在本地主機上運行時，它可以完美運行，並且沒有任何錯誤提示。 將其部署在服務器上的IIS中時，在搜索GridView時開始出現以下錯誤。

Server Error in '/' Application.
Not a valid password.

嘗試了3天，並嘗試了Internet上的許多解決方案，但沒有任何進展。 請幫助。

Answer 1

這是與權限相關的問題。您應使用有效的用戶名/密碼更新web.config身份標記，或更改組策略。 請參閱以下鏈接以了解更多詳細信息。

並且這很有幫助。

Answer 2

當我的表單加載執行此命令時，我得到了相同的錯誤消息

    Me.LPInfoTableAdapter.Fill(Me.EduBaseDataSetLID.LPInfo)

然后我添加了以下代碼行：-

    Me.LPInfoTableAdapter.Connection.ConnectionString = dbProvider & dbSource

這是我在表單加載事件中的完整代碼：-

    'Connect to the access database
    dbProvider = "PROVIDER=Microsoft.ACE.OLEDB.12.0;"
    dbSource = "Data Source = " & dbPath & "\School Edubase\bin\EduBase.accdb;Jet OLEDB:Database Password = P@$$w0rd"

    con.ConnectionString = dbProvider & dbSource

    Me.LPInfoTableAdapter.Connection.ConnectionString = dbProvider & dbSource
    Me.LPInfoTableAdapter.Fill(Me.EduBaseDataSetLID.LPInfo)

我不是專家，甚至都不知道如何解決問題，但是我做到了。 因此，希望這對您有用。
