Десериализация данных json

---

I am new in json.
In my project i need to deserialize json data come from amazon service url .

this is my json  format <a href="
https://s3.amazonaws.com/afb-ses/bounce.json">json list</a>

<pre lang="HTML">{"complaint@simulator.amazonses.com":{"time":"2018-01-02T20:45:46.650Z","type":"Complaint","bounceType":"null","bounceSubType":"null"},
"struax@afb.net":{"time":"2018-01-02T20:53:03.000Z","type":"Bounce","bounceType":"Permanent","bounceSubType":"Suppressed"},
"bounce-test@service.socketlabs.com":{"time":"2018-01-02T21:06:40.097Z","type":"Bounce","bounceType":"Permanent","bounceSubType":"Suppressed"},
"bounce@simulator.amazonses.com":{"time":"2018-01-02T21:08:02.000Z","type":"Bounce","bounceType":"Permanent","bounceSubType":"General"},
"jstrechay@afb.net":{"time":"2018-01-05T06:31:39.000Z","type":"Bounce","bounceType":"Permanent","bounceSubType":"General"},
"leematt45@hotmail.com":{"time":"2018-01-05T06:49:13.000Z","type":"Bounce","bounceType":"Permanent","bounceSubType":"Suppressed"},
"afbweb@afb.net":{"time":"2018-01-07T12:50:38.000Z","type":"Bounce","bounceType":"Transient","bounceSubType":"General"},
"rushjenacath@gmail.com":{"time":"2018-01-05T06:32:42.000Z","type":"Bounce","bounceType":"Permanent","bounceSubType":"Suppressed"},
"Kerryhoskins0925@gmaiil.com":{"time":"2018-01-02T09:18:20.000Z","type":"Bounce","bounceType":"Transient","bounceSubType":"General"}}

мне нужно сохранить эту запись в БД ,и мои столбцы таблицы БД-это электронная почта, тип,время, bounceType, bounceSubType.
я не понимаю, как это сделать, и это ссылка, по которой я получаю json ссылка json для получения подробной информации
заранее спасибо

Что я уже пробовал:

this is i tried

 <pre lang="c#"> using (WebClient wc = new WebClient())
            {
                var json = wc.DownloadString("https://s3.amazonaws.com/afb-ses/bounce.json");
                string jsonData = JsonConvert.SerializeObject(json);
                var _userin = JsonConvert.DeserializeObject(jsonData);

               
            }

в этом коде json десериализуется с древовидной структурой но как сохранить в БД
