Linq与FindAll查找效率引发的思考

        public static void Main()

        {

            var list = new List<BaseData>();

            var rand = new Random();

            

            for (int i = 0; i < 10000000; i++)

            {

                list.Add(new BaseData { Keyword = "啦啦啦", KeywordType = rand.Next(1, 7) });

            }

            Console.WriteLine("construct list finished.");



            var filter = new int[] { 1, 2, 3, 4, 6, 7 };



            var stop = new Stopwatch();

            stop.Start();



            var query = from k in list

                        where k.KeywordType != 5

                        select k;



            stop.Stop();



            Console.WriteLine("linq ticks:" + stop.Elapsed.Ticks);

            Console.WriteLine("linq find result:" + query.Count());





            var stop2 = new Stopwatch();

            stop2.Start();

            

            var query2 = list.FindAll(_ => _.KeywordType != 5);

            

            stop2.Stop();



            Console.WriteLine("find all ticks:" + stop2.Elapsed.Ticks);

            Console.WriteLine("find all result:" + query2.Count);



            



            Console.ReadKey();

        }

结果是：

construct list finished.

linq ticks:1214

linq find result:8333767

find all ticks:7379030

find all result:8333767

今天在网上，Google了半天List的Find、FindAll机制，无果！晚上回来，写了一段小Demo；
发现Linq的性能更好；

Linq的查找机制比Find、FindAll好在哪里？
