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));
