微软消息队列MessageQueue(MQ)

 首先本地安装微软的消息队列服务器。

基础类:

namespace Core.MessageQueueTest
{
    public class TestQueue : IDisposable
    {
        protected MessageQueueTransactionType transactionType = MessageQueueTransactionType.Automatic;
        protected MessageQueue queue;
        protected TimeSpan timeout;
        public TestQueue(string queuePath, int timeoutSeconds)
        {
            queue = new MessageQueue(queuePath);
            timeout = TimeSpan.FromSeconds(Convert.ToDouble(timeoutSeconds));

            // Performance optimization since we don't need these features
            queue.DefaultPropertiesToSend.AttachSenderId = false;
            queue.DefaultPropertiesToSend.UseAuthentication = false;
            queue.DefaultPropertiesToSend.UseEncryption = false;
            queue.DefaultPropertiesToSend.AcknowledgeType = AcknowledgeTypes.None;
            queue.DefaultPropertiesToSend.UseJournalQueue = false;
        }

        /// <summary>
        /// Derived classes call this from their own Receive methods but cast
        /// the return value to something meaningful.
        /// </summary>
        public virtual object Receive()
        {
            try
            {
                using (Message message = queue.Receive(timeout, transactionType))
                    return message;
            }
            catch (MessageQueueException mqex)
            {
                if (mqex.MessageQueueErrorCode == MessageQueueErrorCode.IOTimeout)
                    throw new TimeoutException();

                throw;
            }
        }

        /// <summary>
        /// Derived classes may call this from their own Send methods that
        /// accept meaningful objects.
        /// </summary>
        public virtual void Send(object msg)
        {
            queue.Send(msg, transactionType);
        }

        #region IDisposable Members
        public void Dispose()
        {
            queue.Dispose();
        }
        #endregion

    }
}

测试类:

namespace Core.MessageQueueTest
{
    public class QueueTestOrder : TestQueue
    {
        // Path example - FormatName:DIRECT=OS:MyMachineName\Private$\OrderQueueName
        private static readonly string queuePath =System.Configuration.ConfigurationSettings.AppSettings["OrderQueuePath"];
        private static int queueTimeout = 20;
        public QueueTestOrder()
            : base(queuePath, queueTimeout)
        {
            // Set the queue to use Binary formatter for smaller foot print and performance
            queue.Formatter = new BinaryMessageFormatter();
        }
        /// <summary>
        /// Method to retrieve order messages from Message Queue
        /// </summary>
        /// <returns>All information for an order</returns>
        public new OrderInfo Receive()
        {
            // This method involves in distributed transaction and need Automatic Transaction type
            base.transactionType = MessageQueueTransactionType.Automatic;
            return (OrderInfo)((Message)base.Receive()).Body;
        }

        public OrderInfo Receive(int timeout)
        {
            base.timeout = TimeSpan.FromSeconds(Convert.ToDouble(timeout));
            return Receive();
        }

        /// <summary>
        /// Method to send asynchronous order to  Message Queue
        /// </summary>
        /// <param name="orderMessage">All information for an order</param>
        public void Send(OrderInfo orderMessage)
        {
            // This method does not involve in distributed transaction and optimizes performance using Single type
            base.transactionType = MessageQueueTransactionType.Single;
            base.Send(orderMessage);
        }
    }
     [Serializable]
    public class OrderInfo
    {
        public string Id { get; set; }
        public string Name { get; set; }
    }
}

测试:

 protected void btn_testSendToQueue_Click(object sender, EventArgs e)
        {
            OrderInfo model = new OrderInfo();
            model.Id = "1";
            model.Name = "测试MQ";
            QueueTestOrder order = new QueueTestOrder();
            order.Send(model);
        }

        protected void btn_reciveFromQueue_Click(object sender, EventArgs e)
        {
            QueueTestOrder order = new QueueTestOrder();
            OrderInfo model = new OrderInfo();
            model = (OrderInfo)order.Receive(10);
        }

测试结果:发送\接收信息 正常
