I am trying to get connection string from web.confing of dnn web project to a class inside a class library project. for that i have create a class inside a class library project and define a property to get connection string my code looks like this

Class inside a class library project

public static class Data

    {

public static string ConnectionString

}

connection string inside web.confing of dnn web project

<connectionStrings>

    <add name="shooploopdbcon" connectionString="Data Source=MyServer;Initial Catalog=MyDB;Integrated Security=SSPI;User ID=MyDB;Password=admin;" providerName="System.Data.SqlClient" />

  </connectionStrings>
