system.exception on DateTimeExtensions.FromIso8601 about json.netmf

Hi,

So I reviewed this some more and did some testing, and the code is actually behaving correctly per the JSON spec. When you serialize a DateTime into a JSON string, it must be in a string enclosed in escaped double-quotes. So, your example became ""2015-04-22T22:18:54.000Z"". This is a correctly formatted DateTime in JSON. The datetime conversion utility method is expecting a normal date-time string, not formatted in JSON. So it needs just: "2015-04-22T22:18:54.000Z". In order to achieve this in your code snippet you need to deserialize the serialized object so you need to add a line of code.

 DateTime nowTime = DateTime.Now;
 JsonSerializer dataSerializer = new JsonSerializer(DateTimeFormat.ISO8601);
 string jsonString = dataSerializer.Serialize(nowTime);
 string deserializedJsonString = (string)dataSerializer.Deserialize(jsonString);
 DateTime convertTime = DateTimeExtensions.FromIso8601(deserializedJsonString); 
 Debug.Print("Converted: " + jsonString);

Awesome - the example deserializes into the hashtable, which is the difference that my scenario didn't, and the relevance of that didn't strike me. The interesting thing is that VS's JSON visualizer handled it fine when looking at the local variable, so it must cater for stripping the quotes.

I am hitting another issue but think this one will be harder to figure out - still working through it and will report back separately if I think there's something you can do. I am sending JSON objects over a 2.4ghz wireless link and when I get transmission issues, I always end up with data inconsistencies. which can lead to repeated keys that probably don't get hashtabled too well :)
