Add JObject to JObject

Question

I have a json structure like this:

var json =   {    "report": {},    "expense": {},    "invoices": {},    "projects": {},    "clients": {},    "settings": {      "users": {},      "companies": {},      "templates": {},      "translations": {},      "license": {},      "backups": {},    }  }

I would like to add a new empty Object like "report":{} to the json

My C# code is like this:

JObject json = JObject.Parse(File.ReadAllText("path")); json.Add(new JObject(fm.Name)); 

But it it gives me a exception: Can not add Newtonsoft.Json.Linq.JValue to Newtonsoft.Json.Linq.JObject

So, how can I add a new and empty JObject to the json

Thanks in advance

Answer 1

You are getting this error because you are trying to construct a JObject with a string (which gets converted into a JValue). A JObject cannot directly contain a JValue, nor another JObject, for that matter; it can only contain JProperties (which can, in turn, contain other JObjects, JArrays or JValues).

To make it work, change your second line to this:

json.Add(new JProperty(fm.Name, new JObject()));
