C#获取IP和整数IP方法

体验： http://tool.hovertree.com/info/ip/代码如下：

 using System;
 using System.Text;
 using System.Text.RegularExpressions;
 using System.Web;

 namespace HoverTree.HoverTreeFrame.HvtNet
 {
 public class HoverTreeIP
 {
 /// <summary>
 /// 获取真实IP
 /// </summary>
 /// <returns></returns>
 public static string GetHoverTreeIp()
 {//http://tool.hovertree.com/info/ip/
 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;
 }

 public static bool HvtIsIP(string ip)
 {
 return Regex.IsMatch(ip, @"^((23[0-3]|1\d{2}|[1-9]\d|[1-9])\.)((25[0-5]|2[0-4]\d|1?\d{1,2})\.){2}((25[0-5]|2[0-4]\d|1?\d{1,2}))$") ;
 }

 /// <summary>
 /// 把IP地址转为整数 hovertree.com
 /// </summary>
 /// <param name="ip"></param>
 /// <returns></returns>
 public static long HvtIpToLong(string ip)
 {
 char[] separator = new char[] { '.' };
 string[] items = ip.Split(separator);
 return long.Parse(items[]) <<
 | long.Parse(items[]) <<
 | long.Parse(items[]) <<
 | long.Parse(items[]);
 }

 /// <summary>
 /// 把整数转为IP 何问起
 /// </summary>
 /// <param name="ipLong"></param>
 /// <returns></returns>
 public static string HvtLongToIp(long ipLong)
 {//http://hovertree.com/hvtart/bjae/cn5qrmxw.htm
 StringBuilder sb = new StringBuilder();
 sb.Append((ipLong >> ) & 0xFF).Append(".");
 sb.Append((ipLong >> ) & 0xFF).Append(".");
 sb.Append((ipLong >> ) & 0xFF).Append(".");
 sb.Append(ipLong & 0xFF);
 return sb.ToString();
 }
 }

类的代码将发布在HoverTreeCMS项目中。
