c#中如何操作消息队列
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");
//System.Threading.Thread.Sleep(Convert.ToInt16(System.Configuration.ConfigurationSettings.AppSettings["sleepTime"]));
}
finally
{
SmsQueue.Close();
}
return ret;
}
