Deserialize a JSON file which has nested dictionaries

Question

I have the following JSON file,

 {
 "NAME": {
    "ABC": {
        "Score": 2, 
        "violations": []
    }, 
    "DEF": {
        "Score": 4, 
        "violations": []
    }, 

    "GHI": {
        "Score": 6, 
        "violations": ["badform"]
    }
  }

I am trying to deserilaize this by creating a class but I am finding it very difficult to construct the class as I am either getting nulls or JSON.net crashing. Could anyone tell me the best way to construct the deserializer?

It would be helpful if you showed us what code you have so far — trousyt, Mar 11 '16 at 00:06

This should work (at least it works here if I add missing “}” to the end of JSON file):

using ParsedData = Dictionary<string, Dictionary<string, A>>;

class A {
    public int Score;
    public string[] violations;
}

var parsed = JsonConvert.DeserializeObject<ParsedData>(…);

Another version:

class A {
    public int Score;
    public string[] violations;
}

class B : Dictionary<string, A> {}
class C : Dictionary<string, B> {}

var parsed = JsonConvert.DeserializeObject<C>(…);
