Json.Net cannot deserialize DateTime.MinValue

Question

I tried to deserialize a Json string containing DateTime.MinValueall possible ways, but when the method setis called on my object. The date always changes from -01-01-01- to -01-01-02 -.

Json parsing explicitly contains

"inception_date": "0001-01-01T00:00:00+00:00"

Then I call JsonConverton it:

return JsonConvert.DeserializeObject<T>(json, deserializerSettings);

Where T- this is a basic structure that contains a property: DateTime inception_date { get; set; }. The deserializer settings are as follows:

deserializerSettings = new JsonSerializerSettings()
{
    DateFormatHandling = DateFormatHandling.IsoDateFormat,
    DateParseHandling = Newtonsoft.Json.DateParseHandling.None,
    DateTimeZoneHandling = Newtonsoft.Json.DateTimeZoneHandling.Utc
};

But somewhere in the bowels of Newtonsoft.Json.dll, the specified time is converted to the next jObject.

"inception_date": "0001-01-02T00:00:00Z"

, , . ReadJson JsonConverter serializer.Populate(jObject.CreateReader(), target);, target T, jObject - .

- , ? , jObject , , (DateParseHandling.None).

, , Newtonsoft JsonConvert, .

, , JsonConvert:

dateParseHandling None, .

Newtonsoft JsonConverter, , . JsonReader dateParseHandling:

- , DateTime - jObject DateTime, - , , DateTime, UTC, .

Try:

deserializerSettings = new JsonSerializerSettings()
{
    DateFormatHandling = DateFormatHandling.IsoDateFormat,
    DateParseHandling = Newtonsoft.Json.DateParseHandling.DateTimeOffset
}

, 1/1/0001 12:00:00 AM 1/2/0001 12:00:00 AM

( LINQPad)

void Main()
{
    var deserializerSettings = new JsonSerializerSettings()
    {
        DateFormatHandling = DateFormatHandling.IsoDateFormat,
        DateParseHandling = Newtonsoft.Json.DateParseHandling.None,
        DateTimeZoneHandling = Newtonsoft.Json.DateTimeZoneHandling.Utc
    };
    var json = "{\"inception_date\": \"0001-01-01T00:00:00+00:00\"}";
    var parsedObj = JsonConvert.DeserializeObject<TestClass>(json, deserializerSettings);
    Console.WriteLine(parsedObj);

    deserializerSettings = new JsonSerializerSettings()
    {
        DateFormatHandling = DateFormatHandling.IsoDateFormat,
        DateParseHandling = Newtonsoft.Json.DateParseHandling.DateTimeOffset
    };
    parsedObj = JsonConvert.DeserializeObject<TestClass>(json, deserializerSettings);
    Console.WriteLine(parsedObj);
}

public class TestClass
{
    public DateTime inception_date {get;set;}
}
