大众运输：向所有消费者发送消息并等待他们的回复

Question

On one side I got a custom web page, that sends to me some number of messages for my testing purposes. On another side, I got 4 consumers, that listen to the same queue (round-robin pattern).

Each consumer needs to do a great job, after receiving the message, such as read message, encode the string and create a file, launch another application, send email to a customer.

If I run my solution for one consumer, it works great. But if try to do the same for more then one consumer, I got exceptions.

All I try to do is if I got many messages in a queue, send a message to each consumer and wait for the response from them. Do it while I got messages in a queue.

I will be happy if someone can help me and show where can I find such kind of information or some example.
