Έχουμε και λέμε

            var takeCount = 10;

            var files1 = from file in Directory.GetFiles(@"C:\", "*.*", SearchOption.AllDirectories)
                         orderby new FileInfo(file).Length descending
                         select new { name = file, length = new FileInfo(file).Length };

            foreach (var file in files1.Take(takeCount)) {
                Console.WriteLine(file.length + " " + file.name);
            }

            Console.WriteLine();

            var files2 = from file in Directory.GetFiles(@"C:\", "*.*", SearchOption.AllDirectories)
                         orderby new FileInfo(file).LastWriteTime descending
                         select new { name = file, lastWriteTime = new FileInfo(file).LastWriteTime };

            foreach (var file in files2.Take(takeCount)) {
                Console.WriteLine(file.lastWriteTime + " " + file.name);
            }

            Console.WriteLine();
 

Αυτό που θέλω να ρωτήσω και εγώ με την σειρά μου είναι εάν υπάρχει τρόπος να μην κάνω δύο φορές μέσα στο query, new τη κλάση FileInfo.

Αυτά.
