How to Prevent Date Deserialization in Json.NET's JObject.Parse?

Disabling Date Deserialization in Json.NET with JObject.Parse

Json.NET, a popular JSON handling library, offers flexible deserialization options. By default, it attempts to convert properties with DateTime values into .NET DateTime objects. However, in certain scenarios, this behavior may be undesirable.

Consider the following code:

string s = "2012-08-08T01:54:45.3042880+00:00";

JObject j1 = JObject.FromObject(new { time = s });

Object o = j1["time"];

In this example, o is a string containing the original date-time value. However, if the JSON string is transferred to another program and parsed back using JObject.Parse, the result changes.

JObject j2 = JObject.Parse(j1.ToString());

Object o2 = j2["time"];

Now, o2 is a Date object with a different representation. This discrepancy can be problematic in situations where the original value needs to be preserved.

Solution

To disable date deserialization when using JObject.Parse, Json.NET provides an alternative approach. Instead of using Parse directly, one can use a JsonReader to configure parsing options.

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

By setting DateParseHandling to None before loading the JSON into a JObject, date-time values will be treated as strings, preserving their original format.

Note that this solution relies on the internal Load method of JObject, which is invoked by Parse. This approach offers more control over the deserialization process compared to the default behavior of Parse.
