获取访问者ip:
string userIP; // HttpRequest Request = HttpContext.Current.Request; HttpRequest Request = System.Web.HttpContext.Current.Request; // 如果使用代理，获取真实IP if (Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != "") userIP = Request.ServerVariables["REMOTE_ADDR"]; else userIP = Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; if (userIP == null || userIP == "") userIP = Request.UserHostAddress; return userIP;
获取本机外网ip:
//获取本机外网ip的url string getIpUrl = "http://www.ipip.net/ip.html";//网上获取ip地址的网站 string tempip = ""; WebRequest wr = WebRequest.Create(getIpUrl); Stream s = wr.GetResponse().GetResponseStream(); StreamReader sr = new StreamReader(s, Encoding.UTF8); string all = sr.ReadToEnd(); //读取网站的数据 //解析出需要的数据 int start = all.IndexOf("<th colspan=\"3\">您的当前IP: <span style=\"color: rgb(243, 102, 102);\">"); int end = all.IndexOf("</span></th>"); tempip = all.Substring(start, end - start).Replace("<th colspan=\"3\">您的当前IP: <span style=\"color: rgb(243, 102, 102);\">", ""); sr.Close(); s.Close();
