[rabbitmq-discuss] Many clients using .NET API

Wed Jun 24 09:51:04 BST 2009

Hi,

I've just started to look at RabbitMQ. I'm wondering whether the
following would be an idiomatic use of RabbitMQ from the .NET API:

Routing.Listen("queue1", "#", new ConsoleAlert());

Routing.Listen("queue1", "news.#", new EmailAlert());

Routing.Listen("queue2", "email.#", new ConsoleAlert());

Each call to Listen sets up a thread where the connection and channel
are maintained. 

public static void Listen(string queue, string routing, IRabbitListener
alert)

{

ThreadPool.QueueUserWorkItem(RunThis, new AlertState(queue, routing,
alert));

}

private static void RunThis(object state)

{

var alertState = state as AlertState;

      using (IConnection conn = new
ConnectionFactory().CreateConnection("localhost"))

{

            using (IModel channel = conn.CreateModel())

            {

                  var sub = new Subscription(channel, alertState.Queue,
"topic", alertState.Routing);

                  foreach (BasicDeliverEventArgs e in sub)

{

                        alertState.Alert.OnMessage(e.Exchange,
e.RoutingKey, Encoding.UTF8.GetString(e.Body));

                        sub.Ack(e);

                  }

            }

}

}

Given that .NET processes are more heavy weight than erlang's is this
the preferred way to set up many clients? 

Have I missed something in the .NET API for handling this type of case?

Thanks,

Sam
