        static void OpenMachineConfiguration3()
            // Get the machine.config file applicabe to the
            // specified reosurce and on the specified server.
            System.Configuration.Configuration config =

            int i = 0;
            foreach (ConfigurationSection section in config.Sections)
                    section.SectionInformation.Name + "\t" +
                i += 1;

            Console.WriteLine("[Total number of sections: {0}]", i);
