C # how to automatically obtain the dynamic domain name and port of free natapp on a regular basis
这篇文章主要讲解了"c#怎么实现定时自动获取免费natapp的动态域名和端口"，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习"c#怎么实现定时自动获取免费natapp的动态域名和端口"吧!
一、关闭natapp.exe进程
KillProcess("natapp"); private static void KillProcess(string processName) { Process[] myproc = Process.GetProcesses(); foreach (Process item in myproc) { if (item.ProcessName == processName) { item.Kill(); } } }
二、删除natapp.exe运行产生的log文件
DeleteLog("log.txt");
private static void DeleteLog(string logPath) { DirectoryInfo di = new DirectoryInfo(Environment.CurrentDirectory); FileInfo[] fis = di.GetFiles(); foreach (FileInfo fi in fis) { try { if (fi.Name.Contains(logPath)) { fi.Delete(); } } catch (Exception ex) { } } }
三、启动natapp.exe进程
StartNatappProcess(Environment.CurrentDirectory + "\\natapp\\natapp.exe");
private static void StartNatappProcess(string natappPath) { Process process = new Process(); process.StartInfo.FileName = natappPath; //process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; // 启动的时候最小化程序 process.Start(); Thread.Sleep(1000); }
四、解析natapp.exe运行产生的log文件
ResolveLog("log.txt");
private static void ResolveLog(string logPath) { resolveResult = new ResolveResult(); using (FileStream fs = new FileStream(logPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)) using (StreamReader sr = new StreamReader(fs, Encoding.Default)) { StringBuilder sb = new StringBuilder(); while (!sr.EndOfStream) { sb.AppendLine(sr.ReadLine() + "
"); } string str = sb.ToString(); int x = str.IndexOf("Url"); //定位位置 string validData = str.Substring(x, 100); string[] strTmps = validData.Split('"'); string[] serverStr = strTmps[2].Split(':'); resolveResult.serverUrl = serverStr[0] + ":" + serverStr[1]; if (serverStr.Length>2) { resolveResult.serverPort = int.Parse(serverStr[2]); } resolveResult.localIP = strTmps[10].Split(':')[0]; resolveResult.localPort = int.Parse(strTmps[10].Split(':')[1]); } }

Thank you for reading, the above is the content of "c#how to automatically obtain the dynamic domain name and port of free natapp on a regular basis", after learning this article, I believe everyone has a deeper understanding of how to automatically obtain the dynamic domain name and port of free natapp on a regular basis. The specific use situation also needs to be verified by practice. Here is, Xiaobian will push more articles related to knowledge points for everyone, welcome to pay attention!
