使用Windows Service接收MSMQ消息

Question

I'm creating a Windows Service in C#.

What is the best way to listen for messages?? How do I code this properly??

Answer 1

You don't listen. You configure MSMQ Activation to activate your component when messages arrive. The link has all the details you need, code and configuration.

Answer 2

As previously stated, MSMQ Activation is probably the best way, if you can use that. Alternatively, here is code that I've used:

var ts = new TimeSpan(0, 0, 10);
MessageQueue q = GetQueue<T>();
while (true)
{
  try
  {
    Message msg = q.Receive(ts);
    var t = (T)msg.Body;
    HandleMessage(t);
  }
  catch (MessageQueueException e)
  {
    // Test to see if this was just a timeout.
    // If it was, just continue, there were no msgs waiting
    // If it wasn't, something horrible may have happened
  }
}
