Deserialize JSON from Riot API C#

Question

I have some problem to deserialize JSON response from the RIOT API in C#. I want to get the list of "Champion" and the API return a stream like this :

{  
   "type":"champion",
   "version":"6.1.1",
   "data":{  
      "Thresh":{  
         "id":412,
         "key":"Thresh",
         "name":"Thresh",
         "title":"the Chain Warden"
      },
      "Aatrox":{  
         "id":266,
         "key":"Aatrox",
         "name":"Aatrox",
         "title":"the Darkin Blade"
      },...
    }
}

All data has the same attributes (id, key, name and title) so I create a champion class :

public class Champion
    {
        public int id { get; set; }
        public string key { get; set; }
        public string name { get; set; }
        public string title { get; set; }
    }

I need your help because i dont know how to deserialize this data... I need to create a Root class with type, version and data attributes (data is a list of champion)? I watched for used NewtonSoft Json but I dont found example who helped me.

You can use the following root object (more accurately Data Transfer Object) to retrieve the champions from the API. This will return all champions without having to create a class for each champion.

public class RootChampionDTO
{
    public string Type { get; set; }
    public string Version { get; set; }
    public Dictionary<string, Champion> Data { get; set; }
}

then using Newtsonsoft's Json.NET, you would deserialize using the following:

JsonConvert.DeserializeObject<RootChampionDTO>(string json);

Just a note with Json.NET, if you aren't interested in the type or version properties, you can omit them from your `RootChampionDTO` class and it will still deserialize without any issues. — Seaal, Jan 21 '16 at 10:47

If you want to use NewtonSoft:

JsonConvert.DeserializeObject<RootObject>(string json);

Consider such classes:

public class ResponseModel
{
    public string Type { get; set; }

    public string Version { get; set; }

    public Dictionary<string, Champion> Data { get; set; }
}

public class Champion
{
    public int Id { get; set; }

    public string Key { get; set; }

    public string Name { get; set; }

    public string Title { get; set; }
}

And after use Newtonsoft.Json nuget package to deserialize your json:

 using Newtonsoft.Json;

 var result = JsonConvert.DeserializeObject<ResponseModel>(json);

Note that Newtonsoft.Json default settings allow you to correctly parse camelCase properties from json into PascalCase properties in C# classes.
