Question

怎么在C#中执行DOS命令

Answer 1

public static string RunCmd(string command)//运行一个cmd命令
{
Process p = new Process();
p.StartInfo.WorkingDirectory = "c:\\";
p.StartInfo.FileName = "cmd.exe"; //程序名
p.StartInfo.Arguments = "/c " + command;
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true; //重定向错误输出
p.StartInfo.CreateNoWindow = true; //不显示窗口

p.Start();
return p.StandardOutput.ReadToEnd();

}

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=null;
// p.StandardInput.WriteLine("cd D:\\flv\\mplayer");
// p.StandardInput.WriteLine("cd d:");
p.StandardInput.WriteLine(string.Format("D:\\flv\\mplayer\\mencoder \"c:\\vs.wmv\" -o \"c:\\output.flv\" -of lavf -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames -oac mp3lame -lameopts abr:br=56 -ovc lavc -lavcopts vcodec=flv:vbitrate={0}:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:dia=4:cmp=6:vb_strategy=1 -vf scale=512:-3 -ofps 12 -srate 22050",200));

p.StandardInput.WriteLine("exit");
strOutput = p.StandardOutput.ReadToEnd();
Console.WriteLine(strOutput);
p.WaitForExit();
p.Close();

记得同时要导入：using System.Diagnostics；命名空间。祝你好运
