跟着Artech学习WCF(4) MSMQ 绑定

曾几何时 再看大家讨论各种构架时，经常出现在各个服务器间传递数据，经常出现MSMQ，

那是看到这个心理就郁闷，怎么整天折腾ASP.NET 就没遇见过这个东西

原来这个家伙藏在WCF里面

嘿嘿这次被我发现了

首先 第一次装IIS的话 默认是没有安装msmq 所以需要自己安装的

看Artech 的介绍 这个东西在不能时刻保持和服务器连接的情况下 使用非常有用

对于以WEB为构架为核心的 系统我虽然不知道这个东西有什么用

但我觉得在移动应用中这个东西应该比较有用

移动客户端和服务器端总是若离若弃

但不知道 移动客户端支不支持 这个东西 例如 WINCE ，wp7 支不支持

项目结构图如下

代码如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ServiceModel;
using System.Transactions;
using cfContract;

namespace cfClient
{
    class Program
    {
        static void Main(string[] args)
        {
            ChannelFactory<IOrderProcessor> channelFactory = new ChannelFactory<IOrderProcessor>("defaultEndpoint");
            IOrderProcessor channel = channelFactory.CreateChannel();

            Order order = new Order(Guid.NewGuid(), DateTime.Today, Guid.NewGuid(), "A Company");
            order.OrderItems.Add(new OrderItem(Guid.NewGuid(), "PC", 5000, 20));
            order.OrderItems.Add(new OrderItem(Guid.NewGuid(), "Printer", 7000, 2));

            Console.WriteLine("Submit order to server");
            using (TransactionScope scope = new TransactionScope(TransactionScopeOption.Required))
            {
                channel.Submit(order);
                scope.Complete();
            }
            Console.Read();
        }
    }
}
