Deserialize complex JSON object using c#

Question

I know how to deserialize basic Json object. I am having a problem with nested objects; for example, here is an example json i want to deserialize.

{
    "data": {
        "A": {
            "id": 24,
            "key": "key",
            "name": "name",
            "title": "title"
        },
        "B": {
            "id": 37,
            "key": "key",
            "name": "name",
            "title": "title"
        },
        "C": {
            "id": 18,
            "key": "key",
            "name": "name",
            "title": "title"
        },
        "D": {
            "id": 110,
            "key": "key",
            "name": "name",
            "title": "title"
        }
      },
    "type": "type",
    "version": "1.0.0"
}

Now "data" has an unknown number of objects, could be 100 could be 1000 or could be just 1 and all of them with different name. My ultimate goal is to get the information of each object inside data.

I tried basic json but didn't work at all.

Anyways, this is what I have tried...

I made class called data

public class data
{
    public long id { get; set; }
    public string key { get; set; }
    public string name { get; set; }
    public string title { get; set; }
}

then I made another class called test

public class test
{
    /*
    I have also tried this, which works but then I don't know what to do with it and how to deserialize the information of it.
    //public Newtonsoft.Json.Linq.JContainer data { get; set; }
    */
    public List<List<data>> data { get; set; }
    public string type { get; set; }
    public string version { get; set; }
}

and in my driver application I did this

 string downloadedData = w.DownloadString(link);
 test t = JsonConvert.DeserializeObject<test>(downloadedData);

But this didn't work as I expected to. Any help would be appreciated.

You are looking for a dictionary.

Use this as your class definition:

public class Rootobject
    {
        public Dictionary<string, DataObject> data { get; set; }
        public string type { get; set; }
        public string version { get; set; }
    }
    public class DataObject
    {
        public int id { get; set; }
        public string key { get; set; }
        public string name { get; set; }
        public string title { get; set; }
    }

And this demonstrates that reading your object works:

var vals = @"{

""data"": {
    ""A"": {
        ""id"": 24,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    },
    ""B"": {
        ""id"": 37,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    },
    ""C"": {
        ""id"": 18,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    },
    ""D"": {
        ""id"": 110,
        ""key"": ""key"",
        ""name"": ""name"",
        ""title"": ""title""
    }
  },
""type"": ""type"",
""version"": ""1.0.0""
}";
var obj = JsonConvert.DeserializeObject<Rootobject>(vals);
