Where clause in LINQ Query with Entity Framework -


i trying filter linq query, it's not accepting clause , have no idea kind of lambda function use.

this want, throws error.

var query = s in _db.students s.payments == null orderby s.lastname select s;

assuming payments not field of students, rather property representing collection of payment items related student, try query instead:

var query = s in _db.students !s.payments.any() orderby s.lastname select s;
