{
    // List the prefixes to which the server listens.
    HttpListenerPrefixCollection prefixes = listener.Prefixes;
    if (prefixes.Count == 0)
    {
        Console.WriteLine("There are no prefixes.");
    }
    foreach(string prefix in prefixes)
    {
        Console.WriteLine(prefix);
    }
    // Show the listening state.
    if (listener.IsListening)
    {
        Console.WriteLine("The server is listening.");
    }
}
