防止对DateTime值进行反序列化的时区转换 [英] Prevent timezone conversion on deserialization of DateTime value

问题描述

我有一个我使用 XmlSerializer 序列化/反序列化的类。这个类包含一个 DateTime 字段。

I have a class that I serialize/deserialize using XmlSerializer. This class contains a DateTime field.

当序列化时， DateTime 字段由包含GMT的偏移量的字符串表示，例如 2010-05-05T09：13：45-05：00 。反序列化时，这些时间将转换为执行反序列化的机器的本地时间。

When serialized, the DateTime field is represented by a string that includes the offset from GMT, e.g 2010-05-05T09:13:45-05:00. When deserialized, these times are converted to the local time of the machine performing the deserialization.

由于不值得解释的原因，我想防止这种时区转换发生。序列化发生在野外，这个类的多个版本存在。反序列化发生在受我控制的服务器上。因此，似乎最好在反序列化过程中处理。

For reasons not worth explaining, I'd like to prevent this timezone conversion from happening. The serialization happens out in the wild, where multiple version of this class exist. The deserialization happens on a server that's under my control. As such, it seems like this would be best handled during deserialization.

除了实现 IXmlSerializable 并且手工完成所有的反序列化？

How can I make this happen, other than implementing IXmlSerializable and doing all of the deserialization "by hand?"

推荐答案

而不是解析为 DateTime 可以将其解析为 DateTimeOffset ，并使用 DateTimeOffset.DateTime 属性忽略时区。像这样：

Instead of parsing as a DateTime you can parse it as a DateTimeOffset and use the DateTimeOffset.DateTime property to ignore the timezone. Like this:

[XmlIgnore()]
public DateTime Time { get; set; }

[XmlElement(ElementName = "Time")]
public string XmlTime
{
    get { return XmlConvert.ToString(Time, XmlDateTimeSerializationMode.RoundtripKind); }
    set { Time = DateTimeOffset.Parse(value).DateTime; }
}
