Dim rootWebConfig As System.Configuration.Configuration
    rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("/MyWebSiteRoot")
Dim connString As System.Configuration.ConnectionStringSettings
If (rootWebConfig.ConnectionStrings.ConnectionStrings.Count > 0) Then
    connString = rootWebConfig.ConnectionStrings.ConnectionStrings("NorthwindConnectionString")
    If Not (connString.ConnectionString = Nothing) Then
        Console.WriteLine("Northwind connection string = {0}", connString.ConnectionString)
    Else
        Console.WriteLine("No Northwind connection string")
    End If

			System.Configuration.Configuration rootWebConfig =

			{
				connString =
					rootWebConfig.ConnectionStrings.ConnectionStrings["NorthwindConnectionString"];
				if (connString != null)
					Console.WriteLine("Northwind connection string = \"{0}\"",
