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.

Call MQGetQueueSecurity two times. The first time, set the nLength parameter to 0. The function then informs you of the size that you need for the security descriptor in lpnLengthNeeded.
