JSON.NET append to existing key

#netcore #aspnetcore #csharp #beginners

A quick example for appending to an existing key in a JSON.NET object, since for me at least it wasn't clear in the documentation.

JObject myJson = new JObject(new JProperty("errors", new JObject()));

/// we can now reference it as follows just match the type

myJson["errors"].Value<JObject>().Add(new JProperty("title", title));

Small update:

You can even add multiple entries to an JArray the same way

/// assuming errors is a JArray, this will automatically append new entries
ErrorReponse["errors"].Value<JArray>().Add(new JObject(new JProperty("title", title)));
