Add a new value to a JSON

I've got the following JSON:

    string json = @"{
      'title': ['StarWars'],
      'description': {'StarWars': {'type': 'blog'}}
    }";

I want to add a new value to the description value such as:

string json = @"{
  'title': ['StarWars'],
  'description': {'StarWars': {'type': 'blog', 'add': true}}
}";

The property StarWars inside description property is always the same as the value of title.

How could I add the new property?

I parsed the JSON:

var jObject = JObject.Parse(json);
object.Property("description").AddAfterSelf(new JProperty("add", true));

And I know that's how you add a new property to a json, but I'm not sure how to add a property to a json that's encapsulated in another json.

You can use the following code to add a new token after type

var jObject = JObject.Parse(json);
jObject["description"]?["StarWars"]?["type"]?.Parent?.AddAfterSelf(new JProperty("add", true));

JObject indexer returns a JValue of property, not the property itself, so you should access its Parent to call AddAfterSelf method.

Also, in your code object is invalid name for variable
