要测试网速(非网页速度),发现能找到的资料几乎都是控制台的Ping和发echo包,别无他法.
要测试一台主机到客户机之间的速度无疑需要数据之间的交流.Ping(ICMP包)和echo包,主机是会返回数据的,所以可以用来测试速度.C#中用Socket实现发送icmp包的实现很多,但都不尽容人意,实现的方法实在是让人心忧忧.
ping是icmp协议的一个最有名的应用.在ms 的windows家族中提供了一个专们的ping.exe的工具,供大家差遣.
ping.exe是一个控制台程序,它能够返回执行ping动作的数据结果.
拿来主义.承ms的强大和财大气粗.我将在C#中调用ms的ping.exe程序,并分析返回的结果,得到网络的速度.代码没什么好解释的,自我陶醉一番,只要不是白痴几乎能看懂的.:(
