MQGetQueueSecurity and MQSetQueueSecurity don't have a managed equivalent in the System.Messaging namespace. If you need to read or change the ACL on a queue to, for example, change the queue owner, you need to use P/Invoke to mqrt.dll.

        public static extern uint MQSetQueueSecurity(

            result = mqrt.MQSetQueueSecurity(
