如何从Visual Studio中的网页访问数据库？

Question

I've read and gone through a number of supposed instructions online but none of them are able to help me with my problem.

I'm trying to create a web project that can read from a database and display the values in a table, but every time I try to follow the instructions I find online, I just get errors. This is what my project currently looks like:

And when I run it I get this error:

The database I'm referencing exists in the Server Explorer and has the EMPLOYEE table added. I've tried manually adding the connectionString to the web.config with the line:

<add name="kroger-webpage" connectionString="Data Source=|DataDirectory|\kroger-webpage.mdf" providerName="System.Data.SqlServerCe.4.0"/>

but then I just get the error that the database is corrupted (I'm almost positive it's not.)

I've been trying to get this to work for hours; can someone here help?

经过多次尝试和错误，我最终能够通过更改连接字符串来使此工作正常

<add name="kroger-webpage" connectionString="Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=C:\Users\[me]\source\WebSites\WebSite2\App_Data\kroger-webpage.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
