Yes, but the way JSON.NET deserializes and serializes Dictionaries is as a an array of key value objects (assuming that's what the .NET interface represents).

I've never liked the way this works, but it is the standard way htat JavaScript represents the equivalence of dictionaries. It'd be much clearer if dictionaries serialized into objects that contain key and value properties, but that does get more verbose.

>To be accurate: the json is an object containing a list of name/value pairs. In your case the 'details' item is an array containing three objects, each with it's own name/value pair collection :-}

>>>The issue here is that you're deserializing a list into a dictionary or vice versa. You need to make sure you use the right data type that matches the export. An array maps to an array, list or hashset. Dictionaries serialize different using key/value pair syntax.
