  • There is no such thing as a JSON Array. JSON is a text format, like CSV or XML. – Heretic Monkey Jun 03 '20 at 11:59
  • As such, how do you have this JSON right now? As a string? As an object? – Heretic Monkey Jun 03 '20 at 12:01

    @HereticMonkey Your linked answer is about javascript, not c#. Also, despite being text format json has concept of array elements. – Guru Stron Jun 03 '20 at 12:07
  • @GuruStron JSON has a format for serializing arrays, but it does not have arrays. – Heretic Monkey Jun 03 '20 at 12:09

    @HereticMonkey 1) this is also not a proper duplicate 2) if you don't agree with wording you can dicuss it with [w3schools](https://www.w3schools.com/js/js_json_arrays.asp) or [ietf rfc](https://tools.ietf.org/rfc/rfc7159.txt) having next wording: "This is a JSON array containing two objects:" – Guru Stron Jun 03 '20 at 12:14
  • @GuruStron "this is also not a proper duplicate" is not swaying me with well-reasoned arguments. If you don't feel it answers the question, edit the question to make it clear why it is not (as described in the [help center](https://stackoverflow.com/help/duplicates)). W3Schools is not what I would consider a trustworthy source of anything. I may bring it up with the IETF. – Heretic Monkey Jun 03 '20 at 12:22
  • @HereticMonkey it does not answer the question because it is about adding an object to existing json (which OP knows how to do, see link in my answer) and not a new element to an array in existing json, and there is a difference in handling those in c#, not a big one though. – Guru Stron Jun 03 '20 at 12:28

The approach would be similar to used in answer to your previous question, but you will need to convert element to JArray: 

var x = @"{
    'OrderId':'abc',
    'products':['a','b','c','etc']
}";

var jObj = JObject.Parse(x);
((JArray)jObj["products"]).Add("new");

Try this:

var jObject = JObject.Parse(json); 
var jArray = jObject["products"] as JArray; 
jArray?.Add("new_product");
