無法打開登錄請求的數據庫「ASPNETDB」。登錄失敗。登錄失敗的用戶菲利普桌面菲利普'

Question

我一直在努力尋找這個問題的答案現在幾個小時...

我用來訪問ASPNETDB數據庫時不會出現此錯誤，但不幸的是我不知道我改變了什麼。當我嘗試訪問名爲Admin.aspx的文件時，出現此錯誤，該文件位於名爲Admin的文件夾中。我使用網站管理工具對此文件夾設置了限制，但是當錯誤出現時，我將它們全部關閉以查看問題所在，並且仍然出現錯誤？該Admin.aspx文件是唯一一個獲得誤差..

在web.config中我的連接字符串是：

<add name="WIJLConnectionString1" connectionString="Data Source=localhost;Integrated Security=SSPI; Initial Catalog=ASPNETDB" providerName="System.Data.SqlClient" /> 

以下是錯誤：

有人請幫助！我絕望的在這一點上

Answer 1

錯誤信息是明確的，因爲它可以：

Cannot open database "ASPNETDB" requested by the login. The login failed. Login failed for user 'Philip-Desktop\Philip'

了Windows不允許用戶連接到數據庫，並使用它。

檢查以確保：

• 您在連接字符串中有正確的服務器名稱

  。它真的是localhost？或者你是否安裝了SQL Server Express，結果是(local)\SQLExpress而不是？

• 的服務器你連接到具有Philip-Desktop\Philip登錄（以Object Explorer -> (your server) -> Security -> Logins檢查）

• 的數據庫 ASPNETDB有一個用戶基於該登錄，這樣就可以使用該數據庫（登錄Object Explorer -> (your server) -> Databases -> (your database) -> Security -> Users）

• 您的admin.aspx頁面確實引用了您給出的連接字符串（WIJLConnectionString1）。您的Admin文件夾中是否有單獨的web.config？有不同的連接字符串，並且admin.aspx頁面引用該連接字符串？

感謝您的迴應我找出了錯誤。

顯然，我的所有SqlDataSource連接字符串在Admin.aspx中已經從使用指向正確數據庫（WIJL）的連接字符串更改爲指向ASPNETDB數據庫的連接字符串WIJLConnectionString1。我只需要改變連接字符串
