【问题描述】：

我正在尝试创建一个进程来在我的程序中运行 tcpdump..

这里是代码

            Process tcpdump = new Process();
            tcpdump.StartInfo.FileName= @"/usr/local/bin/tcpdump";
            tcpdump.StartInfo.CreateNoWindow = true;
            tcpdump.StartInfo.Arguments = " -i en1 -c 10 -nn tcp and src host " + ip + " and port " + ports[i];
            tcpdump.Start();
            tcpdump.WaitForExit(); 

但是我得到了错误并且进程没有正确启动 这是我收到的错误消息

open: invalid option -- i
Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-b <bundle identifier>] [-a <application>] [filenames] [--args arguments]
Help: Open opens files from a shell.
      By default, opens each file using the default application for that file.  
      If the file is in the form of a URL, the file will be opened as a URL.
Options: 
      -a                Opens with the specified application.
      -b                Opens with the specified application bundle identifier.
      -e                Opens with TextEdit.
      -t                Opens with default text editor.
      -f                Reads input from standard input and opens with TextEdit.
      -F  --fresh       Launches the app fresh, that is, without restoring windows. Saved persistent state is lost, excluding Untitled documents.
      -R, --reveal      Selects in the Finder instead of opening.
      -W, --wait-apps   Blocks until the used applications are closed (even if they were already running).
          --args        All remaining arguments are passed in argv to the application's main() function instead of opened.
      -n, --new         Open a new instance of the application even if one is already running.
      -j, --hide        Launches the app hidden.
      -g, --background  Does not bring the application to the foreground.
      -h, --header      Searches header file locations for headers matching the given filenames, and opens them.

好吧，我的错，我踢出了我的答案......

【参考方案1】：

问题在于将参​​数传递给 open 命令的方式。

查看 SO 中 similar question 的解决方案。

好吧，我试过了，但我得到了另一个错误 System.ComponentModel.Win32Exception has been throwed ApplicationName='/usr/local/bin/tcpdump', CommandLine=' -i en1 -c 10 -nn tcp和 src 主机 192.168.1.4 和端口 80', CurrentDirectory=''

你能在命令行上使用相同的参数运行 tcddump 吗？我建议，您可以尝试使用另一个简单的命令来确保 Process.Start(..) 正常工作。

OOPPS tcpdump 不在那个文件夹中..这就是为什么它不起作用..我的错 :S ...现在一切都很好:)

我很抱歉，但现在一切正常，但当我添加这部分时 + " > tcpdump.txt";将输出重定向到一个文件..我得到tcp语法错误..虽然当我在shell窗口中使用完全相同的命令时我没有得到任何错误......任何解决方案？？我认为 char > ..... 有什么帮助吗？

嗯，我相信一定有办法绕过 > char... 另一种方法是使用，tcpDump.StartInfo.RedirectStandardOutput = true; //启动进程后... string tcptxt = tcpDump.StandardOutput.ReadToEnd(); StreamWriter lFile = new StreamWriter("tcpdumpOutput.txt" ); lFile.Write(tcptxt.ToString()); lFile.Close(); tcpDump.WaitForExit();
