序列化NodaTime JSON [英] Serialize NodaTime JSON

问题描述

与BCL的DateTime相比，我正在制作NodaTime的原型项目，但是执行此结果会使我recursionLimit超出错误。

I am making a prototype project of NodaTime compared to BCL's DateTime, but executing this result gives me recursionLimit exceeded error.

这是我用来对视图模型进行JSON化的功能。该函数返回后将发生错误。

This is the function I am using to JSONify my viewmodel. The error happens after this function returns.

    [HttpPost]
    public JsonResult GetDates(int numOfDatesToRetrieve)
    {
        List<DateTimeModel> dateTimeModelList = BuildDateTimeModelList(numOfDatesToRetrieve);

        JsonResult result = Json(dateTimeModelList, JsonRequestBehavior.AllowGet);
        return result;
    }

检查模型时，我的视图模型已正确构建。
这是我的视图模型的代码。

My view model is built properly when I inspected it. Here is the code for my view model.

public class DateTimeModel
{
    public int ID;

    public LocalDateTime NodaLocalDateTimeUTC;
    public LocalDateTime NodaLocalDateTime
    {
        get
        {
            DateTimeZone dateTimeZone = DateTimeZoneProviders.Bcl.GetZoneOrNull(BCLTimezoneID);

            //ZonedDateTime zonedDateTime = NodaLocalDateTimeUTC.InUtc().WithZone(dateTimeZone);

            OffsetDateTime offsetDateTime = new OffsetDateTime(NodaLocalDateTimeUTC, Offset.Zero);
            ZonedDateTime zonedDateTime = new ZonedDateTime(offsetDateTime.ToInstant(), dateTimeZone);
            return zonedDateTime.LocalDateTime;
        }
    }

    public OffsetDateTime NodaOffsetDateTime;

    public DateTime BclDateTimeUTC;
    public DateTime BclLocalDateTime
    {
        get
        {
            DateTime utcDateTime = DateTime.SpecifyKind(BclDateTimeUTC, DateTimeKind.Utc);
            TimeZoneInfo nzTimeZone = TimeZoneInfo.FindSystemTimeZoneById(BCLTimezoneID);
            DateTime result = TimeZoneInfo.ConvertTimeFromUtc(utcDateTime, nzTimeZone);
            return result;
        }
    }

    public DateTimeOffset BclDateTimeOffset;
    //public int Offset;
    public string OriginalDateString;
    public string BCLTimezoneID;
}

我确信NodaTime对象未正确序列化，因为当我评论

I am sure that the NodaTime objects are not serializing correctly because when I comment the code from the viewModel the JsonResult is able to execute.

我从本页 NodaTime API参考

此命名空间中的代码目前不包含在Noda Time NuGet软件包中；它仍然被认为是实验性的。要使用这些序列化程序，请从项目主页下载并构建Noda Time源代码。

Code in this namespace is not currently included in Noda Time NuGet packages; it is still deemed "experimental". To use these serializers, please download and build the Noda Time source code from the project home page.

所以我下载并构建了源代码代码并替换了dll的我的项目引用，但我不知道如何实现JsonSerialization类。

So I downloaded and built the source code and replaced the dll's my project references but I don't know how to implement the JsonSerialization classes.

有人可以向我解释如何使用NodaTime.Serialization.JsonNet类使我的NodaTime对象可序列化？

Can someone explain to me how to use NodaTime.Serialization.JsonNet classes to make my NodaTime objects serializable?

推荐答案

我们当前不支持 JavaScriptSerializer code>：我怀疑您必须为您的 all 使用 Json.NET JSON序列化。 有关序列化的用户指南页面给出了一个小位

We don't currently have any support for JavaScriptSerializer: I suspect you'll have to use Json.NET for all your JSON serialization. The user guide page on serialization gives a little bit more information, but it does mostly assume you already know about Json.NET.

好消息是Json.NET易于使用-您可能会发现它是就像这样简单：

The good news is that Json.NET is pretty easy to use - you may well find it's as simple as:

var settings = new JsonSerializerSettings();
settings.ConfigureForNodaTime();
string json = JsonConvert.SerializeObject(model, settings);

（或使用 JsonSerializer 。）

顺便说一句，您使用Noda Time类型的方式至少可以说有点奇怪-可能值得提出另一个有关您的详细信息的问题重新尝试实现，我们可以找到一种更惯用的方法：)

As an aside, the way you're using the Noda Time types is a little odd to say the least - it may well be worth asking another question with details of what you're trying to achieve, and we can work out a more idiomatic way of doing it :)
