insert data into existing JSON Array in C#

Question

I need to add some more data into existing JSON

eg:

{
    "OrderId":"abc",
    "products":["a","b","c","etc"]
}

how to add more into products

There is no such thing as a JSON Array. JSON is a text format, like CSV or XML. — Heretic Monkey

As such, how do you have this JSON right now? As a string? As an object? — Heretic Monkey

@HereticMonkey Your linked answer is about javascript, not c#. Also, despite being text format json has concept of array elements. — Guru Stron

The proper duplicate is json add new object to existing json file C# — Heretic Monkey

@HereticMonkey 1) this is also not a proper duplicate 2) if you don't agree with wording you can dicuss it with w3schools or ietf rfc having next wording: "This is a JSON array containing two objects:" — Guru Stron

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");
