使用ThreadPool代替Thread

using System;
using System.Diagnostics;
using System.Threading;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            var p = new Program();
            Stopwatch sw = new Stopwatch();
            sw.Start();
            p.Thread();
            sw.Stop();
            Console.WriteLine(sw.ElapsedTicks);
            sw.Restart();
            p.Pool();
            sw.Stop();
            Console.WriteLine(sw.ElapsedTicks);
            Console.ReadKey();            
        }

        void Thread()
        {
            for (int i = 0; i < 10; i++)
            {
                var worker = new Thread(() =>
                {
                    //Console.WriteLine("Thread Do");
                });
                worker.Start();
            }
        }

        void Pool()
        {
            for (int i = 0; i < 10; i++)
            {
                ThreadPool.QueueUserWorkItem(state =>
                {
                    //Console.WriteLine("Pool Do");
                });
            }
        }
    }
