Question

Having:

• an entity Person which has a propriety Name
• a List<string> names loaded with some names

How can I query using criteria to obtain all Person instances who have a Name which is not found in the names list?

Thanks for answers!

Solution:

var myQuery = session.CreateCriteria(typeof(Person))
                     .Add(Expression.Not(Expression.In("Name", names));

Answer 1

Your looking for an In expression, see:
Nhibernate HQL where IN query

That would make your particular case something like:

ActiveRecordMediator<Person>.FindAll(Expression.Not(Expression.In("Name", names)))
