讨论c# 调用doc命令问题

Question

现在我要用tracert命令跟踪一批域名的路由现在方案是每调用一次tracert命令创建一个线程每个线程产生了cmd.exe 和tracert.exe两个进程
检测几百个域名，电脑一下子就变成了几百个进程问：有没有方法只开一个cmd.exe和tracert.exe循环检测几百个域名

Answer 1

将需要检测的所有域名存为一个字符串数组，创建一个线程启动cmd，然后一个一个顺序检测就可以了。

Answer 2

LS正解，要是还不明白就去百度“c#线程”吧

Answer 3

现在主要问题是怎么用c#循环输入命令到cmd.exe
能否给个例子

Answer 4

问题解决了，下以是代码，给以后的人用
