how to get data in code behind from api

Question

How to get country name from api codebehind file so i can use it to display in gridview?

foreach (var i in data)
string country = "http://www.geoplugin.net/json.gp?ip=xx.xx.xx.xx"
country=country+"i.ip";
i.Country = country;

Answer 1

Create a class that contains keys from http://www.geoplugin.net/json.gp as String property. The minimum looks like this:

   public class GeoPlugin
    {
        public String geoplugin_countryName { get; set; }
    }

Perform a HttpWebRequest and deserialize the JSON response into the class you created and access the country property:

String url = String.Format("http://www.geoplugin.net/json.gp?ip={0}", "173.194.112.31");
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json";
HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (StreamReader streamReader = new StreamReader(httpWebResponse.GetResponseStream()))
{
   JavaScriptSerializer jss = new JavaScriptSerializer();
   var result = jss.Deserialize<GeoPlugin>(streamReader.ReadToEnd());
   i.Country = result.geoplugin_countryName;
}

To use JavaScriptSerializer you need to reference System.Web.Extensions (Version 4.0 ) and not use the .net 4.0 Client Profile.
