Configuration Management

I wrote the following test class to practice using classes in System.Configuration, especially ConfigurationManager.

using System;
using System.Configuration;
using System.Linq;
using System.Text;

namespace TestConfigurationManager
{
    class Program
    {
        static void Main(string[] args)
        {
            // Get the AppSetting entries
            for (int i=0; i < ConfigurationManager.AppSettings.Count; i++)
            {
                Console.WriteLine("AppSetting key: " + ConfigurationManager.AppSettings.AllKeys[i] + ", value: " + ConfigurationManager.AppSettings[i]);
            }

            // Get the Machine Config located at windows_root\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.config
            Configuration machineConfig = ConfigurationManager.OpenMachineConfiguration();

            ProtectedConfigurationSection protectedConfigSection = (ProtectedConfigurationSection) machineConfig.GetSection("configProtectedData");

            Console.WriteLine("Protected provider default: " + protectedConfigSection.DefaultProvider);
            Console.WriteLine("Here are the providers: ");
            foreach (ProviderSettings settingsColl in protectedConfigSection.Providers)
            {
                Console.WriteLine("\t{0}", settingsColl.Name);
            }

            Console.ReadKey();
        }
    }
}
/*
Output:

AppSetting key: username, value: ptenn
AppSetting key: password, value: pass
AppSetting key: domain, value: mydomain
Protected provider default: RsaProtectedConfigurationProvider
Here are the providers:
        RsaProtectedConfigurationProvider
        DataProtectionConfigurationProvider
