Process起busybox做linux启动盘的问题！很棘手!

/***********************************>>>>问题：strOutput 获得输出了，读完后cmd不退出
如果写这个busybox.exe dd bs=4096k if=atomDemo2g_20090515.img of=/dev/sdb 命令也没法判断是否执行，郁闷,不知道原因

Answer 1

问题看得不是很明白。busybox.exe是什么样的程序？为何要通过cmd而不直接加载？

Answer 2

   Process p = new Process();
            p.StartInfo.FileName = "cmd.exe";
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = true;
            p.Start();
            string strOutput = string.Empty;
            p.StandardInput.WriteLine(cmdinfo);
/*
         
E:\EMP600\workspace\WrtImg\WrtImg\bin\Release>busybox.exe dd bs=4096k if=H:\boot
\imgs\maxdos.img of=/dev/sdb
2+1 records in
2+1 records out
*/
///已经做到这里，读不到records out
            bool finished = false;
            while (!finished) {
                strOutput = p.StandardOutput.ReadLine();//《--------被阻塞在这里了
                if (strOutput.Contains("records out")) {
                    MessageBox.Show(strOutput);
                    p.StandardInput.WriteLine("exit");
                    finished = true;
                }
            
            
            } 
            p.WaitForExit();
            //p.Kill();
            p.Close();
程序目的
在windows下，做一个2G的LINUX恢复盘

Answer 3

烦躁cmd执行可以显示
E:\EMP600\workspace\WrtImg\WrtImg\bin\Release>busybox.exe dd bs=4096k if=H:\boot
\imgs\maxdos.img of=/dev/sdb
2+1 records in
2+1 records out
MessageBox.Show() 就是没有records out
