隐藏选择Nhibernate的属性

Question

我的实体是

public class boUser
{
    public virtual Int32 user_id { get; set; }

    public virtual string name { get; set; }
    public virtual string email_id { get; set; }
    public virtual string password { get; set; }

    public virtual bool is_admin { get; set; }

    public virtual boHome home { get; set; }

    public virtual DateTime registered_date_time { get; set; }




}

从nhibernate中选择时我也得到了我不想要的用户密码，任何人都可以告诉我如何限制获取密码
