How to Deserialize Nested JSON with Dynamic Keys into C# Classes?

Deserialize nested JSON to C# class

Deserialize the JSON response into a C# class. The key is to match the class structure with the entire JSON data. Here is the solution on how to deserialize the given JSON:

JSON structure:

<code>{
    "results": {
        "jobcodes": {
            "1": { ... },
            "2": { ... },
            ...
        }
    }
}</code>

Question:

You are not taking into account the dynamic keys ("1" and "2") in the nested "jobcodes" object.

Solution:

To handle objects with dynamic keys, use Dictionary<string, JobCode>:

class Results
{
    [JsonProperty("jobcodes")]
    public Dictionary<string, JobCode> JobCodes { get; set; }
}

Complete class structure:

class RootObject
{
    [JsonProperty("results")]
    public Results Results { get; set; }
}

class JobCode
{
    [JsonProperty("_status_code")]
    public string StatusCode { get; set; }
    [JsonProperty("_status_message")]
    public string StatusMessage { get; set; }
    [JsonProperty("id")]
    public string Id { get; set; }
    [JsonProperty("name")]
    public string Name { get; set; }
}

Deserialization:

Deserialize JSON to RootObject class:

RootObject obj = JsonConvert.DeserializeObject<RootObject>(jsonResponse);

Result:

You can get obj.Results.JobCodes.Values by visiting List<JobCode>. Each JobCode will have corresponding attribute value from JSON.
