How to Determine the Sort Order of an NHibernate ICriteria Object?

Question

What is the best way to retrieve the list of Orders added to an ICriteria object using the AddOrder method? I believe this will have to be accomplished using Reflection, but what to reflect on?

The purpose of doing this is that I would like to pass the sort order back to the UI so an indication of the sort order can be provided to the user.

Answer 1

var impl = session.CreateCriteria<User>().AddOrder(Order.Asc("Id")) as CriteriaImpl;

foreach (CriteriaImpl.OrderEntry entry in impl.IterateOrderings())
{
Order order = entry.Order;
    // now you have the order and you can either parse it : "propertyName asc" 
                                                         or "propertyName desc"
    // or you can check it out in debug, it has a few protected fields that you could reflect. 
    // not sure if there's another way.
}
