8.WCF消息队列

配置消息队列：

 1 控制面板\所有控制面板项\程序和功能->打开或关闭 Windows 功能。

安装  MSMQ

2. 传统消息队列开发<单机模式>。

   using System.Messaging;   

2.1   接收端：

             static void ReadMessage()
        {
            string queueName = @".\Private$\SampleQueue";
            MessageQueue mq = new MessageQueue(queueName);
            mq.Formatter = new XmlMessageFormatter(new[] { "System.String" });
            Message msg = mq.Receive();
            Console.WriteLine(msg.Label);
            Console.WriteLine(msg.Body.ToString());

        }

   2.2   发送端：

             static void SendMessage()
        {
            Message msg = new Message("这是我的一个消息");

            string queueName = @".\Private$\SampleQueue";
            MessageQueue mq = null;
            if (!MessageQueue.Exists(queueName))
                mq = MessageQueue.Create(queueName);
            else
                mq = new MessageQueue(queueName);
            mq.Formatter = new XmlMessageFormatter(new[] { "System.String" });
            mq.Send(msg, "测试消息");
            Console.WriteLine("消息发送成功");
        }

 

3. WCF 消息队列：

     契约：

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;



using System.ServiceModel;



namespace LearnMSSQ.Service

{

    [ServiceContract]

    [DeliveryRequirements(QueuedDeliveryRequirements = QueuedDeliveryRequirementsMode.Required)]

    public interface IOrder

    {

        /// <summary>

        /// 添加订单  Rhythmk.cnblogs.com

        /// </summary>

        /*

            消息队列可以离线 ，则只能设置成单向访问。

         */

        [OperationContract(IsOneWay=true)]

        void AddOrder(string msg); 

    }

}

 服务方法实现：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.IO;



namespace LearnMSSQ.Service

{

    public class Order:IOrder

    {

        public void AddOrder(string msg)

        {

            string result = string.Format("传入的MSG={0}", msg);

            WriteTxt(result);

           

        }



        private static void WriteTxt(string txt)

        {

            string path = "D:\\MSSQ\\LearnMSSQ\\" + "\\log\\" + DateTime.Now.ToString("yyyyMMdd") + ".log";

            System.IO.StreamWriter sw = new System.IO.StreamWriter(path, true);

            sw.Write(DateTime.Now.ToString()+"\r\n"+txt);

            sw.WriteLine();

            sw.Close();

        }

    }

}

3.2  宿主：

  

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

using System.ServiceModel;
using System.ServiceModel.Dispatcher;
using System.Messaging;
namespace LearnMSSQ.Host
{
    class Program
    {
        static void Main(string[] args)
        {

            // 获取消息队列
            string queueName = System.Configuration.ConfigurationManager.AppSettings["queueName"];
            if (!MessageQueue.Exists(queueName))
            {
                MessageQueue.Create(queueName,true);
            }
            using (ServiceHost host = new ServiceHost(typeof(LearnMSSQ.Service.Order)))
            {
                host.Open();
                Console.WriteLine("WCF - 消息队列已经启动！");
                Console.ReadKey();
            }
        }

    }
}
