Json.NET Disable the deserialization on DateTime

When parsing from an object to JObject you can specify a JsonSerializer which instructs how to handle dates.

JObject.FromObject(new { time = s },
                   new JsonSerializer {
                          DateParseHandling = DateParseHandling.None
                   });

Unfortunately Parse doesn't have this option, although it would make sense to have it. Looking at the source for Parse we can see that all it does is instantiate a JsonReader and then passes that to Load. JsonReader does have parsing options.

You can achieve your desired result like this:

  using(JsonReader reader = new JsonTextReader(new StringReader(j1.ToString()))) {
    reader.DateParseHandling = DateParseHandling.None;
    JObject o = JObject.Load(reader);
  }

For background, see Json.NET interprets and modifies ISO dates when deserializing to JObject #862, specifically this comment from JamesNK: I have no plans to change it, and I would do it again if give the chance.

You can accomplish this using JsonConvert.DeserializeObject as well, by using JsonSerializerSettings:

string s = "2012-08-08T01:54:45.3042880+00:00";
string jsonStr = $@"{{""time"":""{s}""}}";

JObject j1 = JsonConvert.DeserializeObject<JObject>(jsonStr, new JsonSerializerSettings {DateParseHandling = DateParseHandling.None});
