MSMQ的简单使用

static readonly string mqname=@".Private$MSMQ1";


 if (!MessageQueue.Exists(mqname))//判断私有消息是否存在
            {
                MessageQueue.Create(mqname, false);
            }


        private void CreateThread()
        {
            t = new Thread(() =>
            {

                while (true)
                {
                    var mq = new MessageQueue(mqname);
                    System.Messaging.Message message = new System.Messaging.Message();
                    //为了避免存放消息队列的计算机重新启动而丢失消息，可以通过设置消息对象的Recoverable属性为true，
                    //在消息传递过程中将消息保存到磁盘上来保证消息的传递，默认为false。 
                    //message.Recoverable = true;
                    message.Body = new Apple { Name = DateTime.Now.ToString(), Price = r.Next() * 100 };
                    message.Formatter = new XmlMessageFormatter(new Type[] { typeof(Apple) });
                    mq.Send(message);

                    Thread.Sleep(1000);
                }
            });
            t.IsBackground = true;
        }

MSMQ 跨服务器读写队列的“消息队列系统的访问被拒绝”的解决方案：

服务器上消息队列权限设置：给ANONYMOUS LOGON赋予所有权限；

修改服务器的注册表，允许非验证客户端访问

注册表新增HKLMSoftwareMicrosoftMSMQParameterssecurityAllowNonauthenticatedRpc项，设置其DWORD值为1

注册表新增HKLMSoftwareMicrosoftMSMQParameterssecurityNewRemoteReadServerDenyWorkgroupClient项，设置其DWORD值为1

MSMQ的安全访问控制说明参见：http://msdn.microsoft.com/en-us/library/4108f68e-80f5-40e1-b3df-b713cc4dff79(prot.20).aspx

peek和receive的区别：receive后消息队列清空；peek不清空。
