Deserialize nested JSON into C# objects

Question

I am getting JSON back from an API that looks like this:

{
  "Items": {
    "Item322A": [{
      "prop1": "string",
      "prop2": "string",
      "prop3": 1,
      "prop4": false
    },{
      "prop1": "string",
      "prop2": "string",
      "prop3": 0,
      "prop4": false
    }],
       "Item2B": [{
      "prop1": "string",
      "prop2": "string",
      "prop3": 14,
      "prop4": true
    }]
  },
  "Errors": ["String"]
}

I have tried a few approaches to represent this JSON in c# objects (too many to list here). I've tried with lists and dictionaries, here is a recent example of how I've tried to represent it:

    private class Response
    {
        public Item Items { get; set; }
        public string[] Errors { get; set; }
    }

    private class Item
    {
        public List<SubItem> SubItems { get; set; }
    }

    private class SubItem
    {
        public List<Info> Infos { get; set; }
    }

    private class Info
    {
        public string Prop1 { get; set; }
        public string Prop2 { get; set; }
        public int Prop3 { get; set; }
        public bool Prop4 { get; set; }
    }

And here is the method I am using to deserialize the JSON:

    using (var sr = new StringReader(responseJSON))
    using (var jr = new JsonTextReader(sr))
    {
        var serial = new JsonSerializer();
        serial.Formatting = Formatting.Indented;
        var obj = serial.Deserialize<Response>(jr);
    }

obj contains Items and Errors. And Items contains SubItems, but SubItems is null. So nothing except for Errors is actually getting deserialized.

It should be simple, but for some reason I can't figure out the correct object representation

Use this this site for representation:

something like this may help you

public class Item322A
{
    public string prop1 { get; set; }
    public string prop2 { get; set; }
    public int prop3 { get; set; }
    public bool prop4 { get; set; }
}

public class Item2B
{
    public string prop1 { get; set; }
    public string prop2 { get; set; }
    public int prop3 { get; set; }
    public bool prop4 { get; set; }
}

public class Items
{
    public List<Item322A> Item322A { get; set; }
    public List<Item2B> Item2B { get; set; }
}

public class jsonObject
{
    public Items Items { get; set; }
    public List<string> Errors { get; set; }
}

Here is how to deserialize (use JsonConvert class):

jsonObject ourlisting = JsonConvert.DeserializeObject<jsonObject>(strJSON);
