很抱歉格式化。
我正在从数据库接收JSON响应，我需要将日期转换为他/她所在的每个用户的时区。我正在接收的用户时区为“ timezone”：5.5或“ timezone”：-6
仅供参考，我的应用程序正在Azure中运行。我还应该检查夏令时的时区。应用程序是用C＃开发的。我已经尝试过this和this 看起来Nodatime适用于根据时区转换日期。我是一个全新的人，尝试弄清楚如何根据时区更改JSON中的Date值。
我尝试下面的代码来查看日期是否正在更改，但是什么也没有发生。我不确定可以在哪里放置时区。任何帮助表示赞赏。
` var date = "2020-08-12T18:30:13.000";
var json = $"{{\"Date\": \"{date}\"}}";
var pattern = ZonedDateTimePattern.CreateWithInvariantCulture(
"yyyy-MM-dd HH:mm:ss z",
DateTimeZoneProviders.Tzdb
);
var settings = new JsonSerializerSettings
{
DateParseHandling = DateParseHandling.None,
Converters = { new NodaPatternConverter<ZonedDateTime>(pattern) }
};
var dateObj = JsonConvert.DeserializeObject<DateObj>(json, settings);
Console.WriteLine(dateObj.Date);`

答案 0 :(得分：1)
让我知道这是否对您有用。
我没有使用Nodatime，因为我认为不需要时区转换。 我看到的问题是您的datetime不包含任何时区信息。 .Net将其视为本地。 如Microsoft文档所述： The time zone component of DateTimeKind.Utc date and time values uses "Z" (which stands for zero offset) to represent UTC.
编辑（根据@Sanjeev Gautam的评论）：当您的函数在Azure上运行时，您将需要找到一种方法来提取用户的本地时区。在下面的示例中，我使用了 UTC-9 。
指定使用UTC设置日期时间可以实现以下目的：
// Object Class
class DateObj
{
public DateTime Date { get; set; }
}
// JsonConverter
class DateTimeConverterTimeZone : JsonConverter<DateTime>
{
public TimeZoneInfo TimeZone { get; set; }
public DateTimeConverterTimeZone(TimeZoneInfo timezone)
{
TimeZone = timezone;
}
public override void WriteJson(JsonWriter writer, DateTime value, JsonSerializer serializer)
{
writer.WriteValue(value.ToUniversalTime());
}
public override DateTime ReadJson(JsonReader reader, Type objectType, DateTime existingValue, bool hasExistingValue, JsonSerializer serializer)
{
DateTime dt = (DateTime) reader.Value;
var newDateTime= TimeZoneInfo.ConvertTime(dt, TimeZone);
return newDateTime;
}
}
//Deserialization
var date = "2020-08-12T18:30:13.000Z";
var json = $"{{\"Date\": \"{date}\"}}";
var convertedDateTime = JsonConvert.DeserializeObject<DateObj>(json, new DateTimeConverterTimeZone(TimeZoneInfo.FindSystemTimeZoneById("UTC-09")));
