Thanks Radim Köhler,
I found my solution by :
var count = (Int32)Session.CreateCriteria(typeof(Account))
.Add(Restrictions.Eq("Id", account.Id))
.CreateCriteria("Contacts", "Contacts", JoinType.InnerJoin, Restrictions.IsNotEmpty("Addresses"))
.SetProjection(Projections.Count("Id")).UniqueResult();
.
Then I have used following criteria query:
var count = (Int32)Session.CreateCriteria(typeof(Address))
.CreateCriteria("Contact", "Contact",JoinType.InnerJoin)
.Add(Restrictions.Eq("Account.Id",accountId))
.SetProjection(Projections.Count("Id")).UniqueResult();
This give me actual result that I want by optimal query.
