Dictionary<int, string> dic = new Dictionary<int, string>();            for (int i = 0; i < 1000; i++)
            {
                dic.Add(i, "1");
            }
            Stopwatch sw = new Stopwatch();            sw.Start();
            foreach (var kv in dic)
            {
                System.Threading.Thread.Sleep(1);
            }
            sw.Stop();
            Console.WriteLine("花费时间:{0}", sw.ElapsedMilliseconds);            sw.Restart();
            Parallel.ForEach(dic, _ => { System.Threading.Thread.Sleep(1); });
            sw.Stop();
            Console.WriteLine("花费时间:{0}", sw.ElapsedMilliseconds);
