得到这么一段代码用VC++6.0运行，出现下面的错误，可是看不懂，望大虾指点！

using System;
using System.IO;
using System.Net;
using System.Text.RegularExpressions;

class Test
{
  // 获取网页的HTML内容
  static string GetPage(string url)
  {
    HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
    try
    {
      using (HttpWebResponse res = (HttpWebResponse)req.GetResponse())
      {
        using (StreamReader sr = new StreamReader(res.GetResponseStream()))
        {
          return sr.ReadToEnd();
        }
      }
    }
    catch (System.Exception e)
    {
      return e.Message;
    }
    finally
    {
      req.Abort();
    }
  }

  // 通过外部网站得到本机的外部IP
  static string GetOuterIP()
  {
    string patt = @"IP: \[(?<IP>[0-9\.]*)\]";
    string url  = "http://www.skyiv.com/info";
    return Regex.Match(GetPage(url), patt).Groups["IP"].Value;
  }

  static void Main()
  {
    Console.WriteLine("Inner IP:");
    foreach (IPAddress ip in Dns.GetHostEntry(Dns.GetHostName()).AddressList)
    {
      Console.WriteLine(ip);
    }
    Console.WriteLine();
    Console.WriteLine("Outer IP:");
    Console.WriteLine(GetOuterIP());
  }
}

果然是天外来宾

[以专业开发人员为伍]

你贴的根本不是 vc++ 6.0 程序。

先弄清楚是啥程序再弄清楚用啥打开
都整明白了再上来问啥问题

[tommir3]

C++啥时有Class了?
C++我懂的不多,我记得C++没有类吧?

C# code 在 VC++ 6.0 中运行？ 有没有搞错？ 楼主安装个VS2005吧。
