How to get country, city, language for an ip address, in Asp.Net?

When you want to get location information about a client that visits your website according to its ip address you can use a third party service that offers this info in real time or you can use free services, which might not work 100% accurate. However, no matter which service you shall choose you can use the same workflow as I used in my project example.

I created a class that will be used to deserialize json response from api service from easyjquery.com:

 private struct GeoIPResponse
    {
//this is the response I get
        //{"IP":"127.0.0.1","continentCode":"Unknown","continentName":"Unknown",
        //"countryCode2":"Unknown","COUNTRY":"Unknown","countryCode3":"Unknown","countryName":"Unknown","regionName":"Unknown",
        //"cityName":"Unknown","cityLatitude":0,"cityLongitude":0,"countryLatitude":0,"countryLongitude":0,"localTimeZone":"Unknown",
        //"localTime":"0"}
        public string IP;
        public string continentCode;
        public string continentName;
        public string countryCode2;
        public string COUNTRY;
        public string countryCode3;
        public string countryName;
        public string regionName;
        public string cityName;
        public string cityLatitude;
        public string cityLongitude;
        public string countryLatitude;
        public string countryLongitude;
        public string localTimeZone;
        public string localTime;
    }
/*
then I defined some needful methods: 
*/

/// 

    /// Returns Client Ip Address
    /// 
    static public string ClientIpAddress
    {
        get
        {
            string _clientIPAddress = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];
            if (!string.IsNullOrEmpty(_clientIPAddress))
            {
                string[] ipRange = _clientIPAddress.Split(',');
                _clientIPAddress = ipRange[ipRange.Length - 1];
            }
            else
            {
                _clientIPAddress = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];
            }

            return _clientIPAddress;
        }

    }

    public string _WebRequest(string strURL)
    {
        String strResult;
        WebResponse objResponse;
        WebRequest objRequest = HttpWebRequest.Create(strURL);
        objRequest.Method = "GET";

        objResponse = objRequest.GetResponse();
        using (StreamReader sr = new StreamReader(objResponse.GetResponseStream()))
        {
            strResult = sr.ReadToEnd();
            sr.Close();
        }
        return strResult;

    }

and finally this is the way I used a service from www.easyjquery.com: :

protected void Page_Load(object sender, EventArgs e)
{
        txtMessage.Text = "";
        string Result = _WebRequest("http://api.easyjquery.com/ips/?ip=" + ClientIpAddress + "&full=true");

        txtMessage.Text = Result;
        
        JavaScriptSerializer jss = new JavaScriptSerializer();
        var clientGeoLocation = jss.Deserialize < GeoIPResponse >(Result);

        lblMessage.Text = "
Your short details: " + "Country: " + clientGeoLocation.COUNTRY + ", CountryCode 2: " + clientGeoLocation.countryCode2 + ", CountryCode 3: " + clientGeoLocation.countryCode3 +
            ", TimeZone: " + clientGeoLocation.localTimeZone;
}
