怎么获取用户登录的ＩＰ地址？？？

[adu_ado]

我想记录用户操作ＩＰ地址
　　怎么获取？？
一：this.Page.Request.UserHostAddress.ToString();
二： public static string GetIPAddress()
{

string user_IP = string.Empty;
if (System.Web.HttpContext.Current.Request.ServerVariables["HTTP_VIA"] != null)
{
if (System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null)
{
user_IP = System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString();
}
else
{
user_IP = System.Web.HttpContext.Current.Request.UserHostAddress;
}
}
else
{
user_IP = System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"].ToString();
}
return user_IP;
}
还有什么方法，获取最真实的ＩＰ地址

[「已注销」]

string ip = Request.ServerVariables["Remote_Addr"];
string ip = Request.UserHostAddress;

知道的也就lz这样的了
public static string GetIP()
{
string result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
if (string.IsNullOrEmpty(result))
result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

if (string.IsNullOrEmpty(result))
result = HttpContext.Current.Request.UserHostAddress;

if (string.IsNullOrEmpty(result) || !Utils.IsIP(result))
return "127.0.0.1";

return result;
}

足够用了～

[gdlpc]

Request.UserHostAddress.ToString()

[stepday]

Request.UserHostAddress.ToString() 就可以获得登录客户的IP地址的

[mchaojie1]

string ip1 = Request.UserHostAddress;
string ip2 = Request.ServerVariables["Remote_Addr"];

我还直不清楚，在这里学习了啊。

[chw053167]

string ip = Request.ServerVariables["Remote_Addr"];
string ip = Request.UserHostAddress

[lunhuifengzheng]

和LZ用的一样的方法

呵呵 多谢建议~~~

//给你一个比较全的吧 ，能够穿多层代理的，也是引用人的啊

    public static string IPAddress
    {
        get
        {
            string result = String.Empty;

            result = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
            if (result != null && result != String.Empty)
            {
                //可能有代理 
                if (result.IndexOf(".") == -1)    //没有“.”肯定是非IPv4格式 
                    result = null;
                else
                {
                    if (result.IndexOf(",") != -1)
                    {
                        //有“,”，估计多个代理。取第一个不是内网的IP。 
                        result = result.Replace(" ", "").Replace("'", "");
                        string[] temparyip = result.Split(",;".ToCharArray());
                        for (int i = 0; i < temparyip.Length; i++)
                        {
                            if ( IsIPAddress(temparyip[i])
                                && temparyip[i].Substring(0, 3) != "10."
                                && temparyip[i].Substring(0, 7) != "192.168"
                                && temparyip[i].Substring(0, 7) != "172.16.")
                            {


                                return temparyip[i];    //找到不是内网的地址 
                            }
                        }
                    }
                    else if ( IsIPAddress(result)) //代理即是IP格式 
                        return result;
                    else
                        result = null;    //代理中的内容 非IP，取IP 
                }

            }

            string IpAddress = (HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != null && HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] != String.Empty) ? HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"] : HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

            if (null == result || result == String.Empty)
                result = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

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

            return result;
        }
    }

    public static bool IsIPAddress(string str1)
    {
        if (str1 == null || str1 == string.Empty || str1.Length < 7 || str1.Length > 15) return false;
        string regformat = @"^\d{1,3}[\.]\d{1,3}[\.]\d{1,3}[\.]\d{1,3}$";


        Regex regex = new Regex(regformat, RegexOptions.IgnoreCase);
        return regex.IsMatch(str1);
