通过web.config文件建立SQL Server 2008与VS2012项目的连接

Question

I'm trying to connect my database from my SQL Server to my asp.net project through the web.config file. I found code like this which should be able to connect my SQL Server and ASP.net project together properly. However after adding this code, I got this error.

This is my SQL Server connection string that is supposed to be place in web.config :

<connectionStrings>
   <add name="MyConnectionString" 
        connectionString="Data Source=sergio-desktop\sqlexpress;Initial 
                          Catalog=MyDatabase;User ID=userName;Password=password"
        providerName="System.Data.SqlClient" />
</connectionStrings>

And this is the error

I'm also not very sure if the syntax of my connection string to establish connection between the two is correct.

Answer 1

As the error suggests, the connection element should not go in system.web section. it should go in configuration section of your web.config

as

<configuration>
<connectionStrings>
