I want to translate following query from nhibernate criteria query api to linq.
var userquery = session.CreateCriteria(typeof(User))
.SetFirstResult(pageIndex * pageSize)
.SetMaxResults(pageSize);
var totalcountQuery = CriteriaTransformer.Clone(userquery)
.SetProjection(Projections.RowCountInt64());
Thanks
Update
IEnumerable<User> dbUsers = userquery.Future<User>();
IFutureValue<long> count = totalcountQuery.FutureValue<long>();
A direct(ish) translation would be:
var userQuery = session.Query<User>().Skip(pageIndex * pageSize).Take(pageSize);
var totalCount = userQuery.LongCount();
However I'm not sure why you'd want to do the count after the Skip & Take, I would think something like:
var totalCount = session.Query<User>().LongCount();
would be closer to what you want
For futures on Linq, you could do:
var users = userQuery.ToFuture();
var totalCount = userQuery.LongCount(); // users will be a future, count won't be but if it's only 2 queries then this will execute them both
