用这个类：

public string myCmd(string myCommon)
  {
   Process process=new Process();
   process.StartInfo.FileName="cmd.exe";
   process.StartInfo.UseShellExecute=false;
   process.StartInfo.RedirectStandardInput = true;
   process.StartInfo.RedirectStandardOutput = true;
   process.StartInfo.RedirectStandardError = true;
   process.StartInfo.CreateNoWindow = true;

   process.Start();
   process.StandardInput.WriteLine(myCommon);
   process.StandardInput.WriteLine("exit");

   string myResult = process.StandardOutput.ReadToEnd();
   process.Close();
   return myResult;
  }

调用时只需要传入相应的命令行就成
