C# 无效捕获筛选器

我收到一个错误：“tshark:Invalid capture filter”>test1.txt”，用于接口NetToAutomationSlave

---

不能使用

>test1.txt

作为参数重定向标准输出。

当Im试图从OutputDataReceived Im读取数据时，您需要使用来自

OutputDataReceived

事件的数据，并将其记录到txtfile

中，Im仅获取行号，而不获取过滤器？？？例如：如果我尝试将这一行作为参数：“-i3-yip.src==192.168.20.100”，那么get中的输出是“1”

private void OpenTWireShark()
    {
        string path = string.Format(@"-i 3 -Y ip.src==192.168.20.100 > test1.txt"); 
        ProcessStartInfo cmdStartInfo = new ProcessStartInfo();
        cmdStartInfo.FileName = @"C:\Program Files\Wireshark\tshark.exe";
        cmdStartInfo.RedirectStandardOutput = true;
        cmdStartInfo.RedirectStandardError = true;
        cmdStartInfo.RedirectStandardInput = true;
        cmdStartInfo.UseShellExecute = false;
        cmdStartInfo.CreateNoWindow = true;
        cmdStartInfo.Arguments = path;

        Process cmdProcess = new Process();
        cmdProcess.StartInfo = cmdStartInfo;
        cmdProcess.ErrorDataReceived += cmd_Error;
        cmdProcess.OutputDataReceived += cmd_DataReceived;

        cmdProcess.EnableRaisingEvents = true;

        cmdProcess.Start();

        cmdProcess.BeginOutputReadLine();
        cmdProcess.BeginErrorReadLine();

        cmdProcess.WaitForExit();
