【编程】C段 ping操作

利用周末，造个轮子，学习C#！！

官方examples

查看官方的Ping类，已经很成熟了。以下为官方examples

public static void Main (string[] args)
        {
            Ping pingSender = new Ping ();
            PingOptions options = new PingOptions ();

            // Use the default Ttl value which is 128,
            // but change the fragmentation behavior.
            options.DontFragment = true;

            // Create a buffer of 32 bytes of data to be transmitted.
            string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
            byte[] buffer = Encoding.ASCII.GetBytes (data);
            int timeout = 120;
            PingReply reply = pingSender.Send (args[0], timeout, buffer, options);
            if (reply.Status == IPStatus.Success)
            {
                Console.WriteLine ("Address: {0}", reply.Address.ToString ());
                Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
                Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
                Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);
                Console.WriteLine ("Buffer size: {0}", reply.Buffer.Length);
            }
        }

运行结果：

修改

数据显示

官方demo中使用的是默认的Ttl（128），那接下来也使用这个默认值。对demo进行修改，显示所需要的信息即可。

Console.WriteLine ("Address: {0}", reply.Address.ToString ());
Console.WriteLine ("HostName: {0}", Dns.GetHostEntry(reply.Address.ToString()).HostName);
Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);

这只能识别windows系统的，毕竟是128。emmm。

正则匹配IP

使用正则去匹配输入的IP地址是否合理。

// IP地址
Regex regex = new Regex(@"\d+\.\d+\.\d+\.\d+");// (提取IP地址时有用)
// IP地址
Regex regex = new Regex(@"((?:(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d)\\.){3}(?:25[0-5]|2[0-4]\\d|[01]?\\d?\\d))");
// IP地址
