方法一

/// <summary>
        /// 获取客户端的IP，可以取到代理后的IP
        /// </summary>
        /// <returns></returns>
        public static string GetClientIp()
        {
            string l_ret = string.Empty;
            if (!string.IsNullOrEmpty(System.Web.HttpContext.Current.Request.ServerVariables["HTTP_VIA"]))
                l_ret = Convert.ToString(System.Web.HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"]);

            if (string.IsNullOrEmpty(l_ret))
                l_ret = Convert.ToString(System.Web.HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"]);
            return l_ret;
        }

方法二：

        /// <summary>
        /// 获取客户端的IP
        /// </summary>
        /// <returns></returns>
public static string GetRealIP()
{
string ip;
try
{
HttpRequest request = HttpContext.Current.Request;

if (request.ServerVariables["HTTP_VIA"] != null)
{
ip = request.ServerVariables["HTTP_X_FORWARDED_FOR"].ToString().Split(',')[0].Trim();
}
else
{
ip = request.UserHostAddress;
}
}
catch (Exception e)
{
throw e;
}

return ip;
}
