SMS SDK Automation.dll and Collection Rules

Hello,

Has anyone found a way to get the collection query rules out of
SMSCollection? I am running:

SMSCollection oCollection =
oProvider.Collections.Get(CollectionID);

but the rules are located in the (CollectionRules.Non-Public
members.m_alRules.[0].QueryExression ) when I watch oCollection.

How can I get access to the QueryExpression data?

.
