C#获取IP地址

一、获取客户端IP

        public string getIP()
        {
            string result = String.Empty;
            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;
            }
            if (null == result || result == String.Empty)
            {
                return "0.0.0.0";
            }
            return result;
        } 

二、获取服务端IP

 private string  GetIP()
        {
            string StrIp="";

            System.Net.IPAddress[] AddressList = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName()).AddressList;
            for (int i = 0; i < AddressList.Length; i++)
            {
                StrIp += AddressList[i].ToString() + "
";
            }
                return StrIp;
        }
