* 在使用前，一定要注意在头部加上引用：

using System.Net;

代码如下：

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Net;
 5 using System.Text;
 6
 7 namespace ConsoleApplication1
 8 {
 9     class Program
10     {
11         static void Main(string[] args)
12         {
13             Console.Write(new Program().GetHostInfo());
14             Console.ReadLine();
15         }
16         //获取本地IP等信息
17         protected string GetHostInfo()
18         {
19             StringBuilder Info = new StringBuilder("");
20             IPAddress[] ipHost = Dns.GetHostAddresses(Dns.GetHostName());
21             Info.Append("本机名：");
22             Info.Append(Dns.GetHostName());
23             Info.Append(" -> ");
24             Info.Append("IP 地址：");
25             Info.Append(" -> ");
26             foreach (IPAddress address in ipHost)
27             {
28                 Info.Append(address.ToString());
29                 Info.Append(" >> ");
30             }
31             return Info.ToString();
32         }
33     }
