如何将 TimeSpan 序列化为 XML [英] How to serialize a TimeSpan to XML

问题描述

我正在尝试将 .NET TimeSpan 对象序列化为 XML，但它不起作用.一个快速的谷歌建议虽然 TimeSpan 是可序列化的，但 XmlCustomFormatter 不提供将 TimeSpan 对象转换为 XML 或从 XML 转换的方法.

I am trying to serialize a .NET TimeSpan object to XML and it is not working. A quick google has suggested that while TimeSpan is serializable, the XmlCustomFormatter does not provide methods to convert TimeSpan objects to and from XML.

一种建议的方法是忽略用于序列化的TimeSpan，而是序列化TimeSpan.Ticks 的结果(并使用new TimeSpan(ticks)代码> 用于反序列化).一个例子如下:

One suggested approach was to ignore the TimeSpan for serialization, and instead serialize the result of TimeSpan.Ticks (and use new TimeSpan(ticks) for deserialization). An example of this follows:

[Serializable]
public class MyClass
{
    // Local Variable
    private TimeSpan m_TimeSinceLastEvent;

    // Public Property - XmlIgnore as it doesn't serialize anyway
    [XmlIgnore]
    public TimeSpan TimeSinceLastEvent
    {
        get { return m_TimeSinceLastEvent; }
        set { m_TimeSinceLastEvent = value; }
    }

    // Pretend property for serialization
    [XmlElement("TimeSinceLastEvent")]
    public long TimeSinceLastEventTicks
    {
        get { return m_TimeSinceLastEvent.Ticks; }
        set { m_TimeSinceLastEvent = new TimeSpan(value); }
    }
}

虽然这在我的简短测试中似乎有效 - 这是实现这一目标的最佳方式吗?

While this appears to work in my brief testing - is this the best way to achieve this?

是否有更好的方法将 TimeSpan 序列化为 XML 或从 XML 序列化?

Is there a better way to serialize a TimeSpan to and from XML?

推荐答案

您已经发布的方式可能是最干净的.如果你不喜欢额外的属性，你可以实现IXmlSerializable，但是你必须做一切，这在很大程度上违背了这一点.我很乐意使用您发布的方法；它(例如)高效(没有复杂的解析等)、文化独立、明确且时间戳类型的数字很容易被普遍理解.

The way you've already posted is probably the cleanest. If you don't like the extra property, you could implement IXmlSerializable, but then you have to do everything, which largely defeats the point. I'd happily use the approach you've posted; it is (for example) efficient (no complex parsing etc), culture independent, unambiguous, and timestamp-type numbers are easily and commonly understood.

顺便说一句，我经常补充:

As an aside, I often add:

[Browsable(false), EditorBrowsable(EditorBrowsableState.Never)]

这只是将它隐藏在 UI 和引用 dll 中，以避免混淆.

This just hides it in the UI and in referencing dlls, to avoid confusion.
