NHibernate Criteria Collection Contains

public class Parent
{
    public ISet Children { get; set; }
}

public class          


        

Answer 1

How about something like this?

Session.CreateCriteria<Parent>()
   .CreateCriteria("Children")
   .Add(Expression.Eq("Id", child.Id)
   .List<Parent>();

or

Session.CreateCriteria<Parent>()
   .CreateCriteria("Children")
   .Add(Expression.In("Id", child.Id)
   .List<Parent>();

so you can pass in an array of Ids.
