ASP.NET連接字符串不符合規範

Question

Hy！

我在寫一個asp.net應用程序。我首先使用entityframework 5代碼。我在本地開發這個網站，但是我使用了網絡服務器的數據庫。當我發佈這個網站的web服務器，我要補充的連接字符串中這樣說：

<add name="strConn" connectionString="Data Source=localhost;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWORD" /> 

，而不是它：

<add name="constringtwo" connectionString="Server=plumeria.arvixe.com,1433;Database=DBNAME;User Id=DBUSERNAME;Password=DBPASSWORD;" providerName="System.Data.SqlClient" /> 

，當我嘗試打開我的網站，我得到了一個例外。 我寫信給支持我得到了這樣的回答：

你似乎試圖附加數據庫，

<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=aspnet-iAdmin.Web-20130813125200;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnet-iAdmin.Web-20130813125200.mdf" providerName="System.Data.SqlClient" /> 

我不明白，因爲我已經刪除了這個ConnectionString的，怎麼會是誰？ 我將連接字符串的名稱寫入主datacontext，usercontext和websecurity.init。

謝謝期待

Answer 1

有沒有可能是你有你的密碼分號？

例如，我可以這樣做重現您的例外：

new SqlConnection("Data Source=localhost;Initial Catalog=DBNAME;Integrated Security=false;User ID=DBUSERNAME;Password=DBPASSWOR;D;") 

但是，如果我從密碼刪除分號，它的工作原理。

Answer 2

您可能從較高級別的web.config或machine.config繼承連接字符串。爲了避免這種情況，考慮增加一個<clear/>元素的connectionStrings配置部分：

<connectionStrings> 
    <clear/> 
    <add name=... /> 
    ... 

從您的堆棧跟蹤

此外，它看起來就像是SimpleMembershipProvider的是試圖使用違規的連接字符串。您可能希望從您的配置中移除SimpleMembershipProvider，或將其配置爲使用其他連接字符串。
