运行Client和Server两个cpp文件，运行时在设置->link->添加wsock32.lib ,在debug文件中得到两个对应的.exe，然后在dos下运行，在debug文件下输入 Server 2000 ，会显示主机名，再打开一个dos，还是在debug目录下输 Client 主机名 2000 ,就可以客户服务器对话了，输入exit可以退出。-Client and Server both run cpp file, at run-time settings->　link->　add wsock32.lib, at debug document corresponding to two.
