Answer 1

Please see Reading Connection Strings in Web.Config and App.Config and Enterprise Library DAAB Settings (on the Wayback Machine as the original got deleted)

ConnectionStringSettings connection = ConfigurationManager.ConnectionStrings["MyConnectionString"]
string connectionString = connection.ConnectionString

You may need to add an assembly reference to System.Configuration
