MessageQueue .NET进程通信初探

最近写了写了一个小程序，有关于.net进程通信的；以前根本没接触过，还好查了一些资料后；稍微有点明白。对.NET通信也有了一定了解。闲话少说，具体的心得慢慢总结，以后再贴出来。

为模拟两个进程间通信；我在一个solution下见了3个console application；（为区别事务队列和一般队列）；

主程序：

Code
using System;
using System.Messaging;

namespace MyProject
{

    public class MyNewQueue
    {
        public static void Main()
        {
            MyNewQueue myNewQueue = new MyNewQueue();
            Console.WriteLine("Start ReceivMessage and Press Any key to Start!");
            Console.ReadLine();
            myNewQueue.ReceivMessage();
            Console.WriteLine("Then start SendMessageTransation and Press Any key to Start!");
            Console.ReadLine();
            myNewQueue.ReceivMessageTransation();
            Console.WriteLine("Sucess and press any key to exit!");
            Console.ReadLine();
          
        }
        public void ReceivMessage()
        {
            if (!MessageQueue.Exists(".\\Private$\\TestPQueue"))
            {
                MessageQueue myNewPrivateQueue =
                MessageQueue.Create(".\\Private$\\TestPQueue");
            }
            MessageQueue queue = new MessageQueue(@".\Private$\TestPQueue");
            queue.Formatter = new XmlMessageFormatter(new string[] { "System.String" });
            using (MessageEnumerator messages = queue.GetMessageEnumerator2())
            {
                while (messages.MoveNext(TimeSpan.FromSeconds(30)))
                {
                    Message message = messages.Current;
                    message = queue.Receive();
                    Console.WriteLine(message.Body);
                }
               
            }
            return;
        }
        public void ReceivMessageTransation()
        {
            if (!MessageQueue.Exists(".\\Private$\\TestPQueueTransation3"))
            {
                MessageQueue myNewPrivateQueue =
                MessageQueue.Create(".\\Private$\\TestPQueueTransation3", true);
            }
            MessageQueue queue2 = new MessageQueue(@".\Private$\TestPQueueTransation3");
            queue2.Formatter = new XmlMessageFormatter(new string[] { "System.String" });
            MessageQueueTransaction mytransaction = new MessageQueueTransaction();
            try
            {
               
                using (MessageEnumerator messages = queue2.GetMessageEnumerator2())
                {
                    while (messages.MoveNext(TimeSpan.FromSeconds(30)))
                    {
                        mytransaction.Begin();
                        Message message = messages.Current;
                        message = queue2.Receive(mytransaction);
                        Console.WriteLine(message.Body);
                        mytransaction.Commit();
                    }
                }
            }
            catch (MessageQueueException e)
            {
                if (e.MessageQueueErrorCode ==MessageQueueErrorCode.TransactionUsage)
                {
                    Console.WriteLine("Queue is not transactional.");
                }
                mytransaction.Abort();

            }
            return;
        }
    }
}

一般队列(SendMessage):

Code
using System;
using System.Collections.Generic;
using System.Text;
using System.Messaging;

namespace SendMessage
{
    class Program
    {
        static void Main(string[] args)
        {
                if (!MessageQueue.Exists(".\\Private$\\TestPQueue"))
                {
                    MessageQueue myNewPrivateQueue =
                    MessageQueue.Create(".\\Private$\\TestPQueue");
                }
                    MessageQueue queue = new MessageQueue(".\\Private$\\TestPQueue");
                    Console.WriteLine("StartSendMessage");
                    for (int i = 0; i < 5000; i++)
                    {
                        queue.Send("a");
                        queue.Send("b");
                        queue.Send("c");
                        queue.Send("d");
                        queue.Send("e");
                        queue.Send("f");
                        queue.Send("g");
                        queue.Send("h");
                        queue.Send("i");
                        queue.Send("j");
                     }
                Console.WriteLine("Sucess!");
                Console.ReadLine();
        }
    }
}

事务队列（SendMessageTransztion）：

Code
using System;
using System.Collections.Generic;
using System.Text;
using System.Messaging;

namespace SendMessageTransztion
{
    class Program
    {
        static void Main(string[] args)
        {
            if (!MessageQueue.Exists(".\\Private$\\TestPQueueTransation3"))
                {
                    MessageQueue myNewPrivateQueue =
                    MessageQueue.Create(".\\Private$\\TestPQueueTransation3",true);
                }
                MessageQueue queue = new MessageQueue(".\\Private$\\TestPQueueTransation3");
                MessageQueueTransaction transation = new MessageQueueTransaction();
                try
                {
                    transation.Begin();
                    Console.WriteLine("SendMessage..");
                    for (int i = 0;i < 5000; i++)
                   {
                        queue.Send("a", transation);
                        queue.Send("b", transation);
                        queue.Send("c", transation);
                        queue.Send("d", transation);
                        queue.Send("e", transation);
                        queue.Send("f", transation);
                        queue.Send("g", transation);
                        queue.Send("h", transation);
                        queue.Send("i", transation);
                        queue.Send("j", transation);
                    }
                    transation.Commit();
                    Console.WriteLine("Sucess");
                    Console.ReadLine();
                }
                catch 
                {
                    transation.Abort();
                }
            }

        }
    }

先把代码贴出来，慢慢总结心得。
