私はこれを使用します。オブジェクト（JSONから）がnullですか？
RootobjectDribbbleShotsList ObjShots = await DribbbleShotsListProxy.GetShots(App.accesstoken, "debuts", "20", "day", "likes");
ObjShotsは空です。
これはDribbbleShotsListProxyクラスです：
using System.Diagnostics;
using System.IO;
using System.Net.Http;
using System.Runtime.Serialization.Json;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.Serialization;
namespace MyProject
{
public class DribbbleShotsListProxy
{
public async static Task<RootobjectDribbbleShotsList> GetShots(string token, string type, string limit, string timeframe, string sort)
{
var http = new HttpClient();
var url = "https://api.dribbble.com/v1/shots?access_token=" + token + "&list=" + type + "&timeframe=" + "&sort=" + sort + "&per_page=" + limit;
var response = await http.GetAsync(url);
var result = await response.Content.ReadAsStringAsync();
var serializer = new DataContractJsonSerializer(typeof(RootobjectDribbbleShotsList));
var ms = new MemoryStream(Encoding.UTF8.GetBytes(result));
var data = (RootobjectDribbbleShotsList)serializer.ReadObject(ms);
Debug.WriteLine(url);
return data;
}
}

応答が常に有効なJSON（ここでは、応答の例：https://pastebin.com/raw/dLFsc1jg）で、このコードが動作しない理由を私は知らない
。私は常にJSONをオブジェクトに変換するために同じコードを使用し、常に動作します。
