Deserialize recursive JSON object [closed]

Answer 1

Define classes like this:

class Query
{
    [JsonProperty("where")]
    public Clause Where { get; set; }
}

class Clause
{
    [JsonProperty("operator")]
    public string Operator { get; set; }

    [JsonProperty("left")]
    public Clause Left { get; set; }

    [JsonProperty("right")]
    public Clause Right { get; set; }

    [JsonProperty("$fieldref")]
    public string FieldRef { get; set; }

    [JsonProperty("value")]
    public string Value { get; set; }
}

Then you can deserialize like this:

Query q = JsonConvert.DeserializeObject(json);

You can serialize back to JSON like this:

JsonSerializerSettings settings = new JsonSerializerSettings
{
    NullValueHandling = NullValueHandling.Ignore,
    Formatting = Formatting.Indented
};

json = JsonConvert.SerializeObject(q, settings);
