JObject.Parse vs DateTime

Given the following code snippet

String js = "{ \"DateTime\": \"2017-03-07T17:26:40.352Z\" }";
var jo = JObject.Parse(js);
String ds1 = (String)jo["DateTime"];

results "ds1 = “03/07/2017 17:26:40"” which is not quite correct, because it misses fractions of second and timezone information. DateTime.Parse/TryParse will not be correct then. This is a problem in my app, because I want to use DateTime.TryParse to check for correctly formatted input data. I cannot use (DateTime)jo[“DateTime”] because it might throw an exception. (Yes, this exception could be caught, but this is what TryParse is for, isn’t it).

Actually I would have expected ds1 to be “2017-03-07T17:26:40.352Z”, but this may be another story…

Found better one.

JObject.Load method can take a JsonReader as a parameter so we can change its settings without modifying the source code.

JObject jobject;
using(var reader = new JsonTextReader(new StringReader(json)) { DateParseHandling = DateParseHandling.None })
    jobject = JObject.Load(reader);

myObject = jobject["flagment"].ToObject<MyObject>();

Same here.

I wanted to parse a part of object in a JSON string and sadly I wrote something like this:

var jobject = JObject.Parse(json);
var flagment = jobject["Flagment"].ToString(Formatting.None);
JsonConvert.DeserializeObject(flagment);

Made up #1969 to work this around. Hope it will be accepted.
