Here us a quick and dirty sample I just created to show you how its
basically done.

using System;
using Apache.NMS;
using Apache.NMS.Util;
using Apache.NMS.ActiveMQ;
using Apache.NMS.ActiveMQ.Commands;

namespace AdvisoryExample
{
    class AdvisoryExample
    {
        private IConnection connection;
        private ISession session;

        public const String QUEUE_ADVISORY_DESTINATION =
"ActiveMQ.Advisory.Queue";
        public const String TOPIC_ADVISORY_DESTINATION =
"ActiveMQ.Advisory.Topic";
        public const String TEMPQUEUE_ADVISORY_DESTINATION =
"ActiveMQ.Advisory.TempQueue";
        public const String TEMPTOPIC_ADVISORY_DESTINATION =
"ActiveMQ.Advisory.TempTopic";

        public const String ALLDEST_ADVISORY_DESTINATION =
QUEUE_ADVISORY_DESTINATION + "," +

TOPIC_ADVISORY_DESTINATION + "," +

TEMPQUEUE_ADVISORY_DESTINATION + "," +

TEMPTOPIC_ADVISORY_DESTINATION;

        AdvisoryExample()
        {
            IConnectionFactory factory = new ConnectionFactory();

            connection = factory.CreateConnection();
            connection.Start();
            session = connection.CreateSession();
        }

        void EnumerateQueues()
        {
            Console.WriteLine("Listing all Queues on Broker:");

            IDestination dest =
session.GetTopic(QUEUE_ADVISORY_DESTINATION);

            using(IMessageConsumer consumer =
session.CreateConsumer(dest))
            {
                IMessage advisory;

                while((advisory =
consumer.Receive(TimeSpan.FromMilliseconds(2000))) != null)

            }
            Console.WriteLine("Listing Complete.");
        }
