無法連接來自Visual Studio 2008 9.0的SQL Server實例

即使我將Tools-> Options-> Database Tools-> Data Connections設置爲「SIDEKICK」，我在32位XP Professional服務器上從VS獲得以下錯誤「，這是我電腦的名字。換句話說，SIDEKICK應該默認爲完整的SQLSERVER。無法連接來自Visual Studio 2008 9.0的SQL Server實例

換句話說，我希望VS使用SQLSERVER而不是SQLSERVER EXPRESS。我可以清楚地看到服務器資源管理器中的VS以及SSMS 2008中的數據庫。此外，我可以從服務器資源管理器中查看此數據庫的表。我沒有得到任何生成錯誤。它看起來像我的web.config文件中的所有命名是一致的。

我正在開發我的網站根據微軟的教程，所以我不應該得到一個錯誤。然而，我得到下面的異常，當我運行下面這段代碼：

CreateAccounts.aspx.cs文件

protected void CreateAccountButton_Click(object sender, EventArgs e) 
    { 
     MembershipCreateStatus createStatus; 
//This line below is where the exception occurs 
     MembershipUser newUser = Membership.CreateUser(Username.Text, Password.Text, Email.Text, passwordQuestion, SecurityAnswer.Text, true, out createStatus);

這裏是例外的樣子：

       passwordAttemptWindow="10"     
       passwordStrengthRegularExpression=""/> 
     </providers> 
    </membership>

而且我也關閉防火牆，所以我知道th是不是原因。

你的連接字符串是什麼樣的？你可以使用asterix字符掩蓋密碼和IP地址等，但是請張貼完整的字符串。 – 2010-05-02 21:53:13

謝謝Lasse，我剛剛在上面添加了連接字符串。 – salvationishere 2010-05-02 22:06:15

您在「SQL Server配置管理器」中的「SQL Server網絡配置」中啓用了哪些協議？

共享內存和TCP/IP。我需要TCP/IP嗎？ – salvationishere 2010-05-02 23:09:03

如果你在同一個盒子上，你不需要tcp/ip – 2010-05-02 23:10:13

現在我發現了這個問題。問題是我試圖使用完整的SQL Server，而不是Express。完整的SQL Server不支持AttachDBFilename選項，它也不支持User Instance = true。但是，你知道是否選擇TCP/IP的原因當我嘗試從VS打開ASPNET_Users表，通過右鍵單擊並選擇Show Table DAta，我得到的錯誤：無法打開數據庫...請求的登錄。 – salvationishere 2010-05-02 23:12:28

如果您正在使用ASP.NET工作，那麼我會建議你嘗試喜歡用「aspnet_regsql.exe的」實用......基本上可以讓我們改變默認的數據庫連接（這是SQL Express的）東西到我們想要的任何數據庫。此實用程序可以在「C：\ WINDOWS \ Microsoft.NET \ Framework \ v2.0.more- digits」目錄中找到。

我希望這有助於。
