c#怎么网卡MAC
不通过ManagementClass方式，这种方式很容易通过注册表被改掉。。
要低层的。

c#中运行命令行截取输出流的例子
说明:经常有朋友问如何在c#中运行一个dos命令,并截取输出、输出流的问题,这个问题我以前在java中实现过,由于在c#中没有遇到过类似的 情况,为了避免每次别人问都要一遍一遍演示的情况,特地做了一个简单的例子,实现在winform中ping一个网站,并且将ping的结果显示在一个

你将这个改改就能用。
tbResult.Text = ""; ProcessStartInfo start = new ProcessStartInfo("Ping.exe");//设置运行的命令行文件问ping.exe文件，这个文件系统会自己找到 //如果是其它exe文件，则有可能需要指定详细路径，如运行winRar.exe start.Arguments = txtCommand.Text;//设置命令参数 start.CreateNoWindow = true;//不显示dos命令行窗口 start.RedirectStandardOutput = true;// start.RedirectStandardInput = true;// start.UseShellExecute = false;//是否指定操作系统外壳进程启动程序 Process p=Process.Start(start); StreamReader reader = p.StandardOutput;//截取输出流 string line = reader.ReadLine();//每次读取一行 while (!reader.EndOfStream) { tbResult.AppendText(line+" "); line = reader.ReadLine(); } p.WaitForExit();//等待程序执行完退出进程 p.Close();//关闭进程 reader.Close();//关闭流
