如何将TimeSpan序列化为XML

要将TimeSpan序列化为XML，您可以使用C#的内置XML序列化器，例如XmlSerializer类。以下是一个简单的示例，说明如何将TimeSpan对象序列化为XML字符串，并将其反序列化为TimeSpan对象。

首先，定义一个包含TimeSpan属性的类：

using System;

public class TimeSpanData
{
    public TimeSpan TimeSpanValue { get; set; }
}

接下来，创建一个TimeSpanData对象，并将其序列化为XML字符串：

using System;
using System.IO;
using System.Xml.Serialization;

public class TimeSpanData
{
    public TimeSpan TimeSpanValue { get; set; }
}

public class Program
{
    public static void Main()
    {
        TimeSpanData data = new TimeSpanData { TimeSpanValue = new TimeSpan(1, 2, 3, 4, 5) };

        XmlSerializer serializer = new XmlSerializer(typeof(TimeSpanData));
        using StringWriter writer = new StringWriter();
        serializer.Serialize(writer, data);

        string xmlString = writer.ToString();
        Console.WriteLine("Serialized XML:");
        Console.WriteLine(xmlString);
    }
}

这将输出以下XML字符串：

<?xml version="1.0" encoding="utf-16"?>
<TimeSpanData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <TimeSpanValue>P1DT2H3M4.005S</TimeSpanValue>
</TimeSpanData>

最后，反序列化XML字符串为TimeSpanData对象：

using System;
using System.IO;
using System.Xml.Serialization;

public class TimeSpanData
{
    public TimeSpan TimeSpanValue { get; set; }
}

public class Program
{
    public static void Main()
    {
        TimeSpanData data = new TimeSpanData { TimeSpanValue = new TimeSpan(1, 2, 3, 4, 5) };

        XmlSerializer serializer = new XmlSerializer(typeof(TimeSpanData));
        using StringWriter writer = new StringWriter();
        serializer.Serialize(writer, data);

        string xmlString = writer.ToString();
        Console.WriteLine("Serialized XML:");
        Console.WriteLine(xmlString);

        using StringReader reader = new StringReader(xmlString);
        TimeSpanData deserializedData = (TimeSpanData)serializer.Deserialize(reader);

        Console.WriteLine("Deserialized TimeSpanData:");
        Console.WriteLine($"TimeSpanValue: {deserializedData.TimeSpanValue}");
    }
}

这将输出以下内容：

Serialized XML:
<?xml version="1.0" encoding="utf-16"?>
<TimeSpanData xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <TimeSpanValue>P1DT2H3M4.005S</TimeSpanValue>
</TimeSpanData>
Deserialized TimeSpanData:
TimeSpanValue: 1.02:03:04.0050000

这样，您就可以将TimeSpan对象序列化为XML字符串，并将其反序列化为TimeSpan对象。
