如何解析txt文件中的netstat输出并根据PID获取所有远程IP地址作为变量？

Question

背景

我尝试编码所需的桌面 WPF 应用程序允许我选择当前在本地计算机上运行的进程/应用程序，并获取应用程序名称和 PID 并将其存储在变量中。每次用户在选择进程后单击按钮后加载应用程序时，netstat -ano > C:\test.txt都会执行 a。

问题

有没有办法对其进行编码，以便可以将之前获得的应用程序名称和 PID 与文件中匹配的 PID 行进行比较test.txt，然后将远程 IP 地址存储到变量或数组中？谢谢。

为什么要有一个文本文件？这是我解决问题的方法，使用 DataTable 存储数据并收集数据：&nbsp; &nbsp; &nbsp; &nbsp; //Create the process&nbsp; &nbsp; &nbsp; &nbsp; using (Process ns = new Process())&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DataTable dt = new DataTable();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; dt.Columns.AddRange(new DataColumn[] {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new DataColumn("Protocol"),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new DataColumn("Local Address"),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new DataColumn("Foreign Address"),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new DataColumn("State"),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new DataColumn("PID"),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; new DataColumn("Process Name"),&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; });&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ProcessStartInfo psi = new ProcessStartInfo("netstat.exe", "-ano");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; psi.RedirectStandardOutput = true;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; psi.UseShellExecute = false;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ns.StartInfo = psi;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // Run it, and read the results&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ns.Start();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; using (StreamReader r = ns.StandardOutput)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string output = r.ReadToEnd();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; ns.WaitForExit();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //Parse those results into a DataTable, polling the Process info&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string[] lines = output.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (string line in lines)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; string[] elements = line.Split(' ');&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (elements.Length < 5) continue;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (elements.Contains("Proto")) continue;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; DataRow dr = dt.NewRow();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; List<string> validElements = new List<string>();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //Weed out empty elements.&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (string element in elements)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; //skip blanks&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (element.Trim() == "") continue;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; validElements.Add(element);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (string element in validElements)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (DataColumn dc in dt.Columns)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; // fill in the buckets.
