how to put anonymous json as class member and convert all to json in c#

I’m having a well-defined class for sending as JSON body in an HTTP request.

public class EventData
{
    public string deviceJobId { get; set; }
    public int eventID { get; set; }
    public long time_ms { get; set; }
    /// similar fields
}

Now I have to add one more field called HealthInfo. The value of this new HealthInfo is a nested JSON read from some file.
The fields of this JSON file change from time to time, and there is no guarantee that some fields will always be present.

I don’t want to read/modify any value of that and just need to publish this EventData as a json as part of an HTTP request.

Then how to add HealthInfo correctly?

I tried to put HealthInfo as string and object is getting double serialized.

    If you know all of the possible properties inside HealthInfo then you can create new class HealthInfo with nullable properties.

    public class HealthInfo
{
    public string? SomeData { get; set; }
    public int? SomeOtherData { get; set; }
}

    and then add nullable HealthInfo in your main class:

    public class EventData
{
    public string deviceJobId { get; set; }
    public int eventID { get; set; }
    public long time_ms { get; set; }
    public HealthInfo? HealthInfo { get; set; }
    /// similar fields
}

    However if you’re not sure what kind of data you’re gonna get and want to avoid double serialization, just pass HealthInfo as object:

    public class EventData
{
    public string deviceJobId { get; set; }
    public int eventID { get; set; }
    public long time_ms { get; set; }
    public object? HealthInfo { get; set; }
    /// similar fields
}

    you have to convert to JObject before you add new json string

    JObject jo = JObject.FromObject(eventData);

jo["HealthInfo"] = jsonStringHealthInfo;

//or it could be (your question needs some details)
jo["HealthInfo"]=JObject.Parse(jsonStringHealthInfo);

StringContent   content = new StringContent(jo.ToString(), Encoding.UTF8, "application/json");

var response = await client.PostAsync(api, content))

    You can use of C# reflection. (TypeBuilder.DefineProperty Method)
    In fact you must add prop to the class in run time.
