Deserialize (parse) JSON array as System.Array of Object

Question

The following code shows that JSON.NET deserializes arrays as List<object>, but I want object[] instead. Is it possible?

> ((dynamic)JsonConvert.DeserializeObject<ExpandoObject>("{ \"foo\": 1, bar: [5, 6] }")).bar.GetType().FullName
"System.Collections.Generic.List`1[[System.Object, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089]]"

You could create your own version of ExpandoObjectConverter that constructs arrays instead of lists. Just do return list.ToArray(); around line 106. — dbc

Yes, you could simply use the ToArray() method or there is any particular reason you want to do it in one single line (BTW which looks awful) — luis_laurent

Or create a class which defines the bar property as object[] and deserialize to that instead of ExpandoObject. — Heretic Monkey

You could use .ToArray(); on the returned serialized object. Alternatively you could use DeserializeObject(String value, Type type) to try to enforce the type of the returned object.
