NHibernate包含/订购/跳过/获取/选择到新实体的位置

Question

I'm trying to get this query to work with no luck. I have a person object with a first name, last name, id and other fields that should not being returned. The query should return only people where their FULL NAME contains some string value. The query is being used for pagination as well so I have to skip records and take records.

Session.QueryOver<Person>()
  // Only fetch records where full name matches some string (Not working)
  .WhereRestrictionOn(person => person.firstname + " " + person.lastname)
  .IsInsensitiveLike("%bob%")
  // Order by last then first name (Works if removing non-working parts)
  .OrderBy(person => person.lastname)
  .Asc
  .ThenBy(person => person.firstname)
  .Asc
  // Select to different object (Not working)
  .Select(person => new PersonDTO()
  {
    ID = person.ID,
    Name = person.firstname + " " + person.lastname
  })
  // Skip and take (Works if removing non-working parts)
  .Skip(50)
  .Take(50)
  .ToList();

Answer 1

var comboItem = new ComboBoxItem();

var result = Session.QueryOver<Person>()
  .WhereRestrictionOn(person => Projections.Concat(person.firstname, " ", person.lastname))
  .IsInsensitiveLike("%bob%")
  .OrderBy(person => person.lastname)
  .Asc
  .ThenBy(person => person.firstname)
  .Asc
  .SelectList(list => list
    .Select(person => person.ID).WithAlias(() => comboItem.id)
    .Select(person => Projections.Concat(person.firstname, " ", person.lastname)).WithAlias(() => comboItem.text)
  )
  .TransformUsing(Transformers.AliasToBean<ComboBoxItem>())
  .Skip(50)
  .Take(50)
  .List<ComboBoxItem>()
  .ToList();
