ASP.NET登錄控制連接字符串錯誤：不支持關鍵字：'元數據'

Question

我正在使用正常連接，直到現在，一切都很順利，但現在我已切換到數據實體模型，並使用新的連接字符串，我有這個錯誤...我如何保持我的實體字符串為我的數據操作和使用常規conn string僅用於登錄控制？

連接字符串

<connectionStrings>
    <add name="LoginDB" connectionString="Data Source=****;Initial Catalog=int422_113b16;User ID=****;Password=****" />
    <add name="BlogEntities" connectionString="metadata=res://*/App_Code.BlogModel.csdl|res://*/App_Code.BlogModel.ssdl|res://*/App_Code.BlogModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source****;initial catalog=int422_113b16;user id=****;password=****;multipleactiveresultsets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

Answer 1

找到了答案......只是理性思考並檢查配置文件我所要做的就是更改provider標簽的connectionStringName

如果有人遇到同樣的問題，請將來參考

Answer 2

我正在開發一個自定義用戶控件，如果我在測試應用程序中使用它，它仍然可以完美無缺但如果我嘗試部署相同的錯誤，我會得到相同的錯誤，我的自定義控件的代碼后面的行以紅色突出顯示我的瀏覽器：

SqlConnection CriminalConnection = new SqlConnection(strConnectionString);

呃：

不支持關鍵字：'元數據'。

下面是堆棧跟蹤的最初幾行：

System.Data.Common.DbConnectionOptions.ParseInternal（Hashtable parsetable，String connectionString，Boolean buildChain，Hashtable synonyms definitions，Boolean firstKey）+5110852
System.Data.Common.DbConnectionOptions..ctor（String connectionString，Hashtable synonyms definitions，Boolean useOdbcRules）+98

原因在我的情況下，連接字符串格式不正確，詳細說明請訪問http://www.connectionstrings.com/
