我的 Tshark 输出给了我 IP 表，我想按降序显示它们，这是我获得进程输出的代码：

    _process = new ProcessStartInfo(_tsharkPath);
    _process.Arguments = (string.Format("-r {1}{0}{1}  -q -z ip_hosts,tree ", _filePath, "\""));
    _process.WindowStyle = ProcessWindowStyle.Hidden;
    _process.UseShellExecute = false;
    _process.RedirectStandardOutput = true;
    _process.RedirectStandardError = true;
    _process.CreateNoWindow = true;
    _process.UseShellExecute = false;
    _process.ErrorDialog = false;
    Process tsharkProcess = Process.Start(_process);

    StreamReader reader = tsharkProcess.StandardOutput;
    tsharkProcess.WaitForExit(10000);
    List<string> list = new List<string>();
    SortedDictionary<string, string> table = new SortedDictionary<string, string>();

    while (!reader.EndOfStream)
    {
        string read = reader.ReadLine();
        list.Add(read);
    }

我收到了我列表中的表格

这是我的表，我只想重视 IP 和 precent：

Regular Expressions会让你在这里的生活更轻松。首先，定义要捕获的数据的基本结构：

private struct TSharkOutput
{
    public IPAddress ip;
    public uint value;
    public decimal rate;
    public decimal percent;
};

您可以根据需要添加/删除部分并更改数据类型。

接下来是处理这个问题的正则表达式。我将 IPAddress 匹配的首当其冲留给了内部类。

var regTshark = new Regex(@"^\s*(?<ip>[\d.:]+)\s+(?<val>\d+)\s+(?<rate>\d+\.\d+)\s+(?<perc>\d+\.\d+)%", RegexOptions.Compiled);

现在对于您的解析功能，我会做这样的事情；

_process = new ProcessStartInfo(_tsharkPath);
_process.Arguments = (string.Format("-r {1}{0}{1}  -q -z ip_hosts,tree ", _filePath, "\""));
_process.WindowStyle = ProcessWindowStyle.Hidden;
_process.UseShellExecute = false;
_process.RedirectStandardOutput = true;
_process.RedirectStandardError = true;
_process.CreateNoWindow = true;
_process.UseShellExecute = false;
_process.ErrorDialog = false;

var tsharkProcess = Process.Start(_process);
var reader = tsharkProcess.StandardOutput;
tsharkProcess.WaitForExit(10000);
var list = new List<TSharkOutput>();
var regTshark = new Regex(@"^\s*(?<ip>[\d.:]+)\s+(?<val>\d+)\s+(?<rate>\d+\.\d+)\s+(?<perc>\d+\.\d+)%", RegexOptions.Compiled);
Match current;
string line = "";

while (!reader.EndOfStream)
{
    line = reader.ReadLine();
    if ((current = regTshark.Match(line)).Success)
    {
        var shark = new TSharkOutput()
        {
            value = uint.Parse(current.Groups["val"].Value),
            rate = decimal.Parse(current.Groups["rate"].Value),
            percent = decimal.Parse(current.Groups["perc"].Value)
        };

        if (IPAddress.TryParse(current.Groups["ip"].Value, out shark.ip))
            list.Add(shark); // all good add to the list.

    }
}
// sorted is an IEnumerable<TSharkOutput> which has been ordered by the percentage in descending order
var sorted = list.OrderByDescending(ts => ts.percent);

请注意，我现在不在家，所以我无法尝试编译上面的代码，但我相当有信心它的大部分应该可以工作。让我知道。

干杯。
