代码很简单，直接看代码

复制代码 代码如下:

using System;

using System.Net;

using System.Text.RegularExpressions;

namespace Keleyi.Com

{

public class GetInternetIP

{

public static string GetIP()

{

using (var webClient = new WebClient())

{

try

{

var temp = webClient.DownloadString("http://iframe.ip138.com/ic.asp");

var ip = Regex.Match(temp, @"[(?<ip>d+.d+.d+.d+)]").Groups["ip"].Value;

return !string.IsNullOrEmpty(ip) ? ip : null;

}

catch (Exception ex)

{

return ex.Message;

}

}

}

}

}
