using System;
using System.Collections.Generic;
using System.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var data = new[]
                  {

                    new { Name="Granny Smith", Type="Apple", isAvail=false, Price=0.80m, Quantity=7 },
                    new { Name="Gala", Type="Apple", isAvail=true, Price=0.75m, Quantity=10 }

                  };

            var grouped = data.GroupBy(record => record.Type).OrderBy(x => x.Min(y => (Decimal)y.Price));

            foreach (var group in grouped)

                Console.WriteLine("Key {0}", group.Key);

                foreach (var item in group)
                {
                    Console.WriteLine("\t{0}", item.Name);
                } …
