Hi. I have a problem.
I would to assign to a CustumCollection class a IList returned by CreateCriteria method.
In other words I would try a solution that make possible to execute this statement:

CustomCollection coll = (CutomCollection)session.CreateCriteria(typeof(Person)).List();

Someone can halp me?
Thanks,
Gianp.

Is your CustomCollection derrived from ArrayList? If so then do it so:

Code:

CustomCollection coll = new CustomCollection();
coll.AddRange(session.CreateCriteria(typeof(Person)).List());

If you do not have AddRange method then must iterate result collection and insert objects manually...

Thanks for your response.
your suggestion work surely.
But I hoped to try a solution, (working on mapping xml), that return some object that i can cast directly whit my custom Collection, but I not be able to try this solution.
Bye.

You will probably need to create a class that performs NHibernate access operations like IQuery.List(). The method(s) you create that internally calls IQuery.List() can massage the result set anyway it wants, and return any type it wants.
