我正在從事MVC項目。 (現在我正在使用SQL服務器,本地數據庫)我的項目搜索到.mdf文件的App_Data文件夾,web.config設置

我的項目使用MVC項目和數據層項目構建。 (Class Library)

控制器必須從/ To DataLayer從/ To Views(MVC)獲取/傳遞數據。

我面臨着Web.Config和App.Config的問題。

運行該項目時出現以下錯誤。

我很困惑abt爲什麼它尋找App_Data文件夾?

{"The underlying provider failed on Open."} 
{"Cannot attach the file 'D:\\BackUp\\5 may 2014\\MyDBname\\App_Data\\MyDBname.mdf' as database 'MyDBname'."} 

這裏是我的web.config的代碼

<configuration> 
    <configSections> 
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" /> 
    </configSections> 

    <connectionStrings> 
    <add name="SchoolContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=MyDBname;Integrated Security=SSPI;" providerName="System.Data.SqlClient"/> 
    </connectionStrings> 
</configuration> 

這裏是我的app.config的代碼

<?xml version="1.0"?> 
<configuration> 
    <configSections> 
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/> 
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 
    </configSections> 
    <entityFramework> 
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework"> 
     <parameters> 

     <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0; Initial Catalog=MyDBname;Integrated Security=SSPI;" providerName="System.Data.SqlClient" /> 

     </parameters> 
    </defaultConnectionFactory> 
    <providers> 
     <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer"/> 
    </providers> 
    </entityFramework> 
    <startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/> 
    </startup> 
</configuration>

嘗試使用一個連接字符串,這樣反而:

「Data Source =。\ SQLEXPRESS; AttachDbFilename = | DataDirectory | DatabaseName.mdf; Integrated Security = True; User Instance = True

+0

哪裏?在web.config或在App.config? – bnil

+0

把它放在Web.config中 –

+0

不,它仍然在尋找Add_Data文件夾 – bnil
