Csharp 如何在C#中反序列化Java持续时间

这是Noda Time通常用于periods而不是持续时间的格式.遗憾的是，该值中存在多个符号，这意味着您不能使用DurationPattern来解析它--但是PeriodPattern.NormalizingIso似乎可以正常工作:

using NodaTime.Text;

var pattern = PeriodPattern.NormalizingIso;
var result = pattern.Parse("PT-328H-46M-43.2082074S");
var period = result.Value;
var duration = period.ToDuration();

Console.WriteLine(duration);

要在System.Text.Json以内使用它，您需要指定正确的句号模式...然后潜在地从一段时间到整个持续时间都是一种"蹦床".下面是一个完整的例子:

Program.cs:

using NodaTime;
using NodaTime.Serialization.SystemTextJson;
using NodaTime.Text;
using System.Text.Json;

string json = """
{
  "name": "Jon",
  "duration": "PT-328H-46M-43.2082074S"
}
""";

var settings = new NodaJsonSettings
{
    PeriodConverter = new NodaPatternConverter<Period>(PeriodPattern.NormalizingIso)
};
var options = new JsonSerializerOptions().ConfigureForNodaTime(settings);

var model = JsonSerializer.Deserialize<Model>(json, options);
Console.WriteLine(model.Duration);

Model.cs:

using NodaTime;
using System.Text.Json.Serialization;

public class Model
{
    [JsonPropertyName("name")]
    public string Name { get; set; }

    [Obsolete]
    [JsonPropertyName("duration")]
    public Period Period
    {
        // TODO: A getter, if you want to be able to serialize back.
        // That's a little more work as there isn't a Duration.ToPeriod conversion.
        set => Duration = value.ToDuration();
    }

    [JsonIgnore]
    public Duration Duration { get; set; }
}
