JSON Question

C# Parse Json with multiple objects and arrays newtonsoft

I'm attempting to parse a rather convoluted/unnecessarily complicated JSON output using newtonsoft in C# however for some reason my parser always returns null. I have searched all over SO and cant't seem to find a solution.

An example of a JSON file I'm trying to parse:

{
"success": 1,
"d": {
"gameData": {
"MJ2Y7tDg": {
"scores": [
{
"max": 1.83,
"avg": 1.73,
"rest": 2,
"active": true,
"scoreid": "2c556xv464x0x4vtqc"
},
{
"max": 3.47,
"avg": 3.24,
"rest": 2,
"active": true,
"scoreid": "2c556xv498x0x0"
},
{
"max": 6.06,
"avg": 5.08,
"rest": 1,
"active": true,
"scoreid": "2c556xv464x0x4vtqd"
}
],
"count": 62,
"highlight": [
false,
true
]
},
"jZICYUQu": {
"scores": [
{
"max": 2.25,
"avg": 2.13,
"rest": null,
"active": true,
"scoreid": "2c5guxv464x0x4vuiv"
},
{
"max": 3.55,
"avg": 3.29,
"rest": null,
"active": true,
"scoreid": "2c5guxv498x0x0"
},
{
"max": 3.9,
"avg": 3.33,
"rest": null,
"active": true,
"scoreid": "2c5guxv464x0x4vuj0"
}
],
"count": 62,
"highlight": [
false,
false
]
}
}
}
}


This is what i have so far, I am very new to JSON wrangling :)

public class RootObject
{
public int success { get; set; }
public List<d> d { get; set; }
}

public class d
{
public List<gameData> gameData { get; set; }
}

public class gameData
{
public IDictionary<string, Score> gameData{ get; set; }
public List<scores[]> GameList;
}
public class Score
{
public double max { get; set; }
public double avg { get; set; }
public int rest { get; set; }
public bool active { get; set; }
public string scoreid { get; set; }
}


Anyone with more JSON wrangling experience know how to get this working?

Thankyou in advanced.
P.S I am currently in high school, learning C#

Answer

The parser returns null because structure of your classes doesn't correctly resemble the structure of JSON. The correct structure of classes would be:

public class RootObject
{
    public int success { get; set; }
    public Class_d d { get; set; }
}

public class Class_d
{
    public Dictionary<string, GameData> gameData { get; set; }
}

public class GameData
{
    public List<Score> scores { get; set; }
    public int count { get; set; }
    public bool[] highlight { get; set; }
}

public class Score
{
    public decimal max { get; set; }
    public decimal avg { get; set; }
    public int? rest { get; set; }
    public bool active { get; set; }
    public string scoreid { get; set; }
}

and you can use it as follows:

string json = "..."; // the JSON in your example
RootObject root = JsonConvert.DeserializeObject<RootObject>(json);
