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();
}
}
}
}
