什麼是解析這個過程輸出（tshark的putput）

Question

我tshark的出把給我的IP的表，我想向他們展示在decending秩序的最佳方式，這是我的代碼誰得到的過程輸出：

_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); 
    } 

我正在收到表我的列表

這是我的表，我只希望值IP和precent內：

Answer 1

Regular Expressions將使你的生活有很多在這裏更容易。首先，確定你想要獲取的數據的基本結構：

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

您可以添加/刪除部分和更改數據類型的需要。

接下來是正則表達式來處理這個問題。我將IPAddress的主力留給了內部類。

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

現在爲您的解析功能，我會做這樣的事情;

_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); 

請注意，我不在家，現在，所以我一直沒能嘗試編譯上面的代碼，但我相當確信其中大部分應該工作。讓我知道。

乾杯。
