Question

I am using MSMQ as a way to provide asynchronous SOA. Please refer to the code below as it’s quite hard to explain. I am trying to figure out the best way to do it.

//another method reads off MSMQ and passes the Message into this method public void ReadMSMQAndAction(Message m) {   var e = m.Entity;    /* this is really bad, but i some how still need some     * kind of traffic cop to direct action */   switch typeof(m.Entity)     case Order.GetType()       switch e.Action         case 'SAVE'           //todo OrderRepo Save }  //Message gets searlized and put into MSMQ public class Message<T> {   public T Entity { get;set; }    /* should this be string?    * or some kind of rule i.e. 'ClassName:MethodName' etc? */   public string Action { get;set; }  }  public class OrderRepo {   public void Save(Order o) { /* todo */ }   public void Delete(Order o) { /* todo */ }   public void Update(Order o) { /* todo */ } } 

As the code gets more complex it’ll be really hard to manage. Any suggestions are welcome!

Look into using delegates. They will allow you to pass the actual method call into the MSMQ so that you can then fire the delegate/action when you retrieve it from the queue.
