Grouping using Linq in MVC

Try this code..

var results = from p in persons
              group p.car by p.PersonId into g
              select new { PersonID = g.Key, Cars = g.ToList() };

or incase of chain statement..

var results = persons.GroupBy(p => p.PersonId, p => p.car,
                         (key, g) => new { PersonId = key, Cars = g.ToList() });

If this solves your issue kindly up vote and mark this as solution.. Thanks..
