Destroy nested JSON in C # objects

Question

I get JSON back from the API, which 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 tried several approaches for representing this JSON in C # objects (too many to list here). I tried with lists and dictionaries, here is a recent example of how I tried to present 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 use to deserialize 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 . Thus, nothing but Errors is actually deserialized.

It should be simple, but for some reason I cannot understand the correct representation of the object

Answer 1

For "Items" use Dictionary<string, List<Info>> , i.e.:

 class Response { public Dictionary<string, List<Info>> Items { get; set; } public string[] Errors { get; set; } } class Info { public string Prop1 { get; set; } public string Prop2 { get; set; } public int Prop3 { get; set; } public bool Prop4 { get; set; } } 

It is assumed that the names of the item "Item322A" and "Item2B" will vary from answer to answer and will read these names in the form of dictionary keys.

Use this site to submit:

something like this might 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's how to deserialize (use the JsonConvert class):

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