Question

我将连接字符串连接到我的Entity Framework MVC4程序时遇到了一些麻烦。

这是我的连接字符串：

<connectionStrings>
    <add name="testContext" 
     connectionString="Data Source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=C:\folders\SQL\SQL\App_Data\TEST1.mdf;"
     providerName="System.Data.SqlClient" />
</connectionStrings>

这是我的错误代码：

An exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.dll but was not handled in user code

Additional information: Directory lookup for the file "C:\folders\SQL\SQL\App_Data\TEST1.mdf" failed with the operating system error 5(Access is denied.).

CREATE DATABASE failed. Some file names listed could not be created. Check related errors.

Answer 1

用户似乎正在运行应用程序，因为无法访问c：\ folders ....目录。

另一个问题（一旦解决了第一个问题）就是你错过了连接字符串中的“Database”参数。

connectionString="Data Source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=C:\folders\SQL\SQL\App_Data\TEST1.mdf;Database=dbnamehere;"
