        as NameValueCollection;

    // Get the collection enumerator.
    IEnumerator appSettingsEnum =
        appSettings.GetEnumerator();

    // Loop through the collection and
    // display the appSettings key, value pairs.
    int i = 0;
    Console.WriteLine("[Display appSettings]");
    while (appSettingsEnum.MoveNext())
    {

' Show the use of AppSettings property
' to get the application settings.
Shared Sub GetAppSettings()
   
   ' Get the appSettings key,value pairs collection.

      Dim key As String = appSettings.AllKeys(i)
