Serialize an object directly to a JObject instead of to a string in json.net

Question

How might one serialize an object directly to a JObject instance in JSON.Net? What is typically done is to convert the object directly to a json string lik

Answer 1

You can use FromObject static method of JObject

JObject jObj = JObject.FromObject(someObj)

Answer 2

Please note that the JObject route suggested by @Eser will work only for non-array CLR objects. It results in below exception if you try converting an Array object to JObject:

An unhandled exception of type 'System.InvalidCastException' occurred in Newtonsoft.Json.dll

Additional information: Unable to cast object of type 'Newtonsoft.Json.Linq.JArray' to type 'Newtonsoft.Json.Linq.JObject'.

So, in case it is an array object then you should be using JArray instead as shown below:

JArray jArray = JArray.FromObject(someArrayObject);

Please include using Newtonsoft.Json.Linq; at the top of your code file to use this code snippet.

Answer 3

To combine everything: use JToken for everything (Objects AND Arrays).

JToken token = JToken.FromObject(someObjectOrArray);

Then check through token.Type which JTokenType it is (Object, Array or otherwise).
