    Console.WriteLine();
    Console.WriteLine("Using AppSettings property.");
    Console.WriteLine("Application settings:");
    // Get the KeyValueConfigurationCollection 
    // from the configuration.
    KeyValueConfigurationCollection settings =
      config.AppSettings.Settings;

    // Display each KeyValueConfigurationElement.
    foreach (KeyValueConfigurationElement keyValueElement in settings)
    {
        Console.WriteLine("Key: {0}", keyValueElement.Key);
        Console.WriteLine("Value: {0}", keyValueElement.Value);
