c#中如何操作消息队列

Answer 1

“消息”是在两台计算机间传送的数据单位。消息可以非常简单，例如只包含文本字符串；也可以更复杂，可能包含嵌入对象。 消息被发送到队列中。“消息队列”是在消息的传输过程中保存消息的容器。消息队列管理器在将消息从它的源中继到它的目标时充当中间人。队列的主要目的是提供路由并保证消息的传递；如果发送消息时接收者不可用，消息队列会保留消息，直到可以成功地传递它。 c#中发往消息队列中发送消息 public bool SendMessage(string title, string body){MessageQueue SmsQueue = new MessageQueue();try{string mqPath = System.Configuration.ConfigurationSettings.AppSettings["SiteEnvironmentMQPath"];//给基站告警用的（wz的程序） string MQPath = string.Format(@"FormatName:DIRECT=TCP:{0}", mqPath); SmsQueue.MessageReadPropertyFilter.Body = true; SmsQueue.MessageReadPropertyFilter.AppSpecific = true; SmsQueue.MessageReadPropertyFilter.Priority = true; SmsQueue.Formatter = new System.Messaging.XmlMessageFormatter(new Type[] { typeof(string) }); SmsQueue.Path = MQPath; Message objMsg = new Message(); objMsg.Label = title; objMsg.Body = body; SmsQueue.Send(objMsg); return true;}catch (Exception ex){return false;}finally{SmsQueue.Close();}}c# 从消息队列中取消息 public string ReceiveMessage(string mqPath){string ret = ""; MessageQueue SmsQueue = new MessageQueue();try{string MQPath = string.Format(@"FormatName:DIRECT=TCP:{0}", mqPath); //string MQPath = System.Configuration.ConfigurationSettings.AppSettings["MQPath"]; SmsQueue.MessageReadPropertyFilter.Body = true; SmsQueue.MessageReadPropertyFilter.AppSpecific = true; SmsQueue.MessageReadPropertyFilter.Priority = true; SmsQueue.Formatter = new System.Messaging.XmlMessageFormatter(new Type[] { typeof(string) }); SmsQueue.Path = MQPath; Message objMsg = SmsQueue.Receive(); ret = objMsg.Body.ToString();}catch (Exception ex){//LogClass.WriteLog("错误", DateTime.Now.ToString(), ex.Message, "从消息队列读取告警数据");
