ASP.NET如何获取用户的IP - .NET技术 / ASP.NET

网站后台管理需要显示登录人员的IP。最好能显示IP地址的归属地，请教各位大虾如何实现呀？最好能有源码，谢谢！！

---

HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

---

归属地可以用一个数据库来查询，也可以用web service。

---

从Request流中获取
Request.UserHostAddress

归属地需要ip数据库,很多网站有这样的功能,提一个http请求就能获取到

参考

private string GetClientIP()
  {
  string result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
  if (null == result || result == String.Empty)
  {
  result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
  }

  if (null == result || result == String.Empty)
  {
  result = HttpContext.Current.Request.UserHostAddress;
  }
  return result;
  }
