Criteria question with NHibernate

Question

I'm trying to use NHibernate for data access, and I have 2 simple entities that look like this:

public class User : IEntity
{
   public int ID { get; set; }
   public string FirstName { get; set; }
   public string LastName { get; set; }
   public string Email { get; set; }
   public string Logon { get; set; }
   public string Password { get; set; }
   public ICollection<Role> Roles { get; set; }

   public bool IsNew
   {
      get { return (ID == 0) ? true : false; }
   }

   public User()
   {
      Roles = new List<Role>();
   }
}

public class Role : IEntity
{
   public int ID { get; set; }
   public string RoleName { get; set; }
   public string RoleDescription { get; set; }

   public bool IsNew
   {
      get { return (ID == 0) ? true : false; }
   }
}

My question......how do I construct a Criteria if I want to find any user that contains a Role with an ID of 1 in it's Roles collection?

Answer 1

Never mind, this ended up being relatively straight forward to do:

// role was the role passed in to my Find method.
var criteria = DetachedCriteria.For(typeof (User))
            .CreateCriteria("Roles")
            .Add(Restrictions.Eq("ID", role.ID));
