C#获取本机IP地址和Mac地址的代码
查找了几个方法，经过调试修改，下面这个方法能很好的获取到本地的IP和MAC地址。可以用于这方面的功能实现。主要是要添加System.Management的引用。

using System;  using System.Management;  using System.Net;      public class Program      {          static void Main(string[] args)          {              try              {                  string ip = "";                  string mac = "";                  ManagementClass mc;                  string hostInfo = Dns.GetHostName();                  //IP地址                  //System.Net.IPAddress[] addressList = Dns.GetHostByName(Dns.GetHostName()).AddressList;这个过时                    System.Net.IPAddress[] addressList = Dns.GetHostEntry(Dns.GetHostName()).AddressList;                  for (int i = 0; i < addressList.Length; i++)                  {                      ip = addressList[i].ToString();                  }                  //mac地址                  mc = new ManagementClass("Win32_NetworkAdapterConfiguration");                  ManagementObjectCollection moc = mc.GetInstances();                  foreach (ManagementObject mo in moc)                  {                      if (mo["IPEnabled"].ToString() == "True")                      {                          mac = mo["MacAddress"].ToString();                      }                  }                  //输出                  string outPutStr = "IP:{0},\n MAC地址:{1}";                  outPutStr = string.Format(outPutStr, ip, mac);                  Console.WriteLine(outPutStr);              }              catch (Exception e)              { }              Console.ReadLine();          }      }
