通過互鎖來掌握同步的程式設計
using System;using System.Collections.Generic;using System.Diagnostics;using System.Linq;using System.Runtime.InteropServices;using System.Text;using System.Threading;namespace ConsoleApplication1{    class Program    {        private static char buffer;        private static long numberOfUsedSpace = 0;        static void Main(string[] args)        {            Thread writer = new Thread(delegate()            {                 string sentence = "無可奈何花落去，似曾相識燕歸來，小園香徑獨徘徊";                 for(int i=0;i<24;i++)                 {                        while (Interlocked.Read(ref numberOfUsedSpace) == 1) { Thread.Sleep(10); }                        buffer = sentence[i];                        Interlocked.Increment(ref numberOfUsedSpace);                 }              });            Thread Reader = new Thread(delegate()            {                for(int i=0;i<24;i++)                {                    while (Interlocked.Read(ref numberOfUsedSpace) == 0) { Thread.Sleep(10); }                    char ch = buffer;                    Console.Write(ch);                    Interlocked.Decrement(ref numberOfUsedSpace);                }            });            writer.Start();            Reader.Start();                    }                       }       }

 學習掌握Lock語句來實現線程的同步
