Deserialize array from JSON in C#

So I am trying to deserialize an array from JSON into a C# class using Newtonsoft. I have seen tutorials and other questions on this, but I am running into problems as the array I want to get is not at the top level of the JSON. The JSON is structured like this, where I want to extract the "data" array and deserialize it:

 "success": true,
  "data": [
    {      
      "key": "americanfootball_nfl",
      "active": true,
      "group": "American Football",
      "details": "US Football",
      "title": "NFL",
      "has_outrights": false
    },
    {
      "key": "aussierules_afl",
      "active": true,
      "group": "Aussie Rules",
      "details": "Aussie Football",
      "title": "AFL",
      "has_outrights": false
    },
    {
      "key": "basketball_euroleague",
      "active": true,
      "group": "Basketball",
      "details": "Basketball Euroleague",
      "title": "Basketball Euroleague",
      "has_outrights": false
    }
]}

I know that I first need to extract the data object from the JSON, and then parse that, but I am not too sure how. I have this class to deserialize the JSON:

public class SportsModel
    {       
        public bool Success { get; set; }
        public string Data { get; set; }       
    }

    public class SportsData
    {
        public string Key { get; set; }
        public bool Active { get; set; }
        public string Group { get; set; }
        public string Details { get; set; }
        public string Title { get; set; }
        public bool HasOutrights { get; set; }
    }

And currently get the top level of the data using this:

SportsModel data = JsonConvert.DeserializeObject<SportsModel>(response);

I want to put the JSON array data into a list object, so that I can access it all

What you can do is; go to visual studio and in edit menu menu and paste special and click then paste json as class.

But first you need to copy the json string first.

You only need to fix this part to make the serializer understand you're deserializing the Data field into a type of SportsData and not a string.

public class SportsModel
{
   public bool Success { get; set; } 
   public List<SportsData> Data { get; set; } 
}

Update To get data into a list, I would assume you are referring to something of this nature

SportsModel result = JsonConvert.DeserializeObject<SportsModel>(response);
var sportsDataList = result.Data;

Your SportModels class needs to be updated to:

public class SportsModel
{
   public bool Success { get; set; } 
   public List<SportsData> Data { get; set; } 
}


SportsModel result = JsonConvert.DeserializeObject<SportsModel>(response);

And you will Data in a List.
