Read DynamicJsonArray with razor (mvc4 Umbraco) - json

Question

I'm reading Json from https://demoapi.thismoment.com/v4.1/api/content
Reading it as stream:
Stream stream = wc.OpenRead(url);
using (StreamReader reader = new StreamReader(stream))
{
String request = reader.ReadToEnd();
var requestJson = #Json.Decode(request);
and getting list of results
var resultsList = new List<dynamic>(requestJson.results);
When trying to read next level
var resultsList = new List<dynamic>(requestJson.results.media);
I'm getting this error: System.ArgumentNullException: Value cannot be null.
When I iterate through the list
foreach (var item in resultsList)
{
<a>#item.media</a>
}
each media item is System.Web.Helpers.DynamicJsonArray.
I need to read this array, so I can get url and size of each image.
The above json url is public.
I'm doing it in Umbraco 7, which uses razor code (aps mvc 4).

You can use following method to do it:
private static List<T> GetcollectionFromJason<T>(string jasonUrl) where T : new()
{
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(jasonUrl);
List<T> retCollection = new List<T>();
try
{
WebResponse response = request.GetResponse();
using (Stream responseStream = response.GetResponseStream())
{
if (responseStream != null)
{
StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
string jsonString = reader.ReadToEnd();
JavaScriptSerializer serializer = new JavaScriptSerializer();
retCollection = serializer.Deserialize<List<T>>(jsonString);
}
}
}
catch (WebException exp)
{
WebResponse errorResponse = exp.Response;
using (Stream responseStream = errorResponse.GetResponseStream())
{
if (responseStream != null)
{
StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
String errorText = reader.ReadToEnd();
}
}
}
return retCollection;
}
And to call it you can have this:
List<YourModel> technicalIssues = GetcollectionFromJason<YourModel>(YourJsonUrl);
