Subqueues

How do I create a subqueue for dead lettering messages with MSMQ?

Subqueues are a relatively new feature of MSMQ that do not actually involve creating a new physical queue. Instead, the subqueue represents a logical group of messages that are stored inside the parent physical queue. Messages can cheaply move between the parent queue and the subqueue.

Since there is no physical queue being created, the distinguishing feature of subqueues must therefore be the address used to put messages into the queue. The subqueue syntax adds to the URI scheme for referring to a queue. Here is the URI scheme for net.msmq.

net.msmq://hostname/[private/]queuename[;subqueuename]

The bracketed sections in the above scheme represent the optional parts.
