原文 获取外网IP, C#获取本机的MAC地址，C#通过编程方式实现Ping
思路是通过WebRequest连接一些网上提供IP查询服务的网站，下载到含有你的IP的网页，然后用正则表达式提取出IP来
class Program { static void Main(string[] args) { Console.WriteLine(GetExportIP()); Console.ReadKey(); } public static string GetExportIP() { //获取外部IP string strUrl = "http://www.ip.cn/getip.php?action=getip&ip_url=&from=web"; //string strUrl = "http://216.157.85.151/getip.php?action=getip&ip_url=&from=web"; Uri uri = new Uri(strUrl); WebRequest webreq = WebRequest.Create(uri); Stream s = webreq.GetResponse().GetResponseStream(); StreamReader sr = new StreamReader(s, Encoding.Default); string all = sr.ReadToEnd(); all = Regex.Replace(all,@"(\d+)","000$1"); all = Regex.Replace(all, @"0+(\d{3})", "$1"); string reg = @"(\d{3}\.\d{3}\.\d{3}\.\d{3})"; Regex regex = new Regex(reg); Match match = regex.Match(all); string ip = match.Groups[1].Value; return Regex.Replace(ip,@"0*(\d+)","$1"); } }
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Management; namespace _17获取MAC地址 { class Program { static void Main(string[] args) { ManagementObjectSearcher nisc = new ManagementObjectSearcher("select * from Win32_NetworkAdapterConfiguration"); foreach (ManagementObject nic in nisc.Get()) { if (Convert.ToBoolean(nic["ipEnabled"]) == true) { Console.WriteLine("{0} - {1}", nic["ServiceName"], nic["MACAddress"]); } } Console.ReadKey(); } } }
废话少说，具体代码如下：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net.NetworkInformation; namespace _20通过编程方式实现Ping { class Program { static void Main(string[] args) { Ping ping = new Ping(); PingOptions pingOpt = new PingOptions(); pingOpt.DontFragment = true;//是否设置分段数据 string myInfo = "Hello, world！"; byte[] bufferInfo = Encoding.ASCII.GetBytes(myInfo); int timeOut = 1200; string ipTarget = "192.168.1.102"; PingReply pingReply = ping.Send(ipTarget, timeOut, bufferInfo); if (pingReply.Status == IPStatus.Success) { Console.WriteLine("耗费时间 - {0}\n路由节点数 - {1}\n数据分段 - {2}\n缓冲区大小 - {3}", pingReply.RoundtripTime, //耗费时间 pingReply.Options.Ttl, //路由节点数 pingReply.Options.DontFragment ? "发生分段" : "没有发生分段",//数据分段 pingReply.Buffer.Length//缓冲区大小 ); } else { Console.WriteLine("无法ping通"); } Console.ReadKey(); } } }
