Why does this anonymous type not deserialize properly using JsonConvert.DeserializeAnonymousType?

There are two problems here, as far as I can tell:

• You don't have a response property to deserialize
• The "token:123 id:191" part is actually just a string - the value of the outer token property

So if you change your code to:

var def = new
{
    response = new { token = "" }
};

var deserializedToken = JsonConvert.DeserializeAnonymousType(json, def);
Console.WriteLine(deserializedToken);

then you'll end up with:

{ response = { token = {"token":"123","id":191} } }

If you want to deserialize the token/id part as well, you can do that with:

var innerDef = new { token = "", id = "" };
var deserializedInner = JsonConvert.DeserializeAnonymousType
    (deserializedToken.response.token, innerDef);
Console.WriteLine(deserializedInner);

That then prints:

{ token = 123, id = 191 }
