Hi!
Why I can't serialize TimeSpan structure with XmlSerializer? This is what I
do:
using System;
using System.IO;
using System.Xml;
using System.Xml.Seri alization;
namespace ConsoleApplicat ion1
{
/// <summary>
/// Summary description for Class1.
/// </summary>
public class Class1
{
public TimeSpan span = new TimeSpan(1, 2, 3);
public DateTime time = new DateTime(1, 1, 1, 1, 1, 1, 1);
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
XmlSerializer serializer = new XmlSerializer(t ypeof(Class1));
XmlTextWriter xmlwriter = new XmlTextWriter(" c:\\testser.xml ",
System.Text.Enc oding.Unicode);
Class1 c = new Class1();
c.span = new TimeSpan(3, 2, 1);
serializer.Seri alize(xmlwriter , c);
xmlwriter.Close ();
}
}
}
And this is what I get::
<?xml version="1.0" encoding="utf-16" ?>
- <Class1 xmlns:xsd="http ://www.w3.org/2001/XMLSchema"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance">
<span />
<time>0001-01-01T01:01:01.001 0000+02:00</time>
</Class1>

Ivan,
It looks like the TimeSpan structure doesn't serialize as expected with the
XmlSerializer. However, there is a workaround. If you tell the serializer
to ignore the TimeSpan and include a property that provides access to the
ticks off the TimeSpan, you can serialize that. Look at the following
modification to your code:
using System;
using System.IO;
using System.Xml;
using System.Xml.Seri alization;
namespace ConsoleApplicat ion1
{
/// <summary>
/// Summary description for Class1.
/// </summary>
public class Class1
{
[XmlIgnore]
public TimeSpan span = new TimeSpan(1, 2, 3);
public DateTime time = new DateTime(1, 1, 1, 1, 1, 1, 1);
public long elapsedTicks
{
get { return span.Ticks; }
set { span = new TimeSpan(value) ; }
}
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main(string[] args)
{
XmlSerializer serializer = new XmlSerializer(t ypeof(Class1));
XmlTextWriter xmlwriter = new XmlTextWriter(" c:\\testser.xml ",
System.Text.Enc oding.Unicode);
Class1 c = new Class1();
c.span = new TimeSpan(3, 2, 1);
serializer.Seri alize(xmlwriter , c);
xmlwriter.Flush ();
xmlwriter.Close ();
}
}
}
Using this, I had the following results from the program:
<?xml version="1.0" encoding="utf-16" ?>
- <Class1 xmlns:xsd="http ://www.w3.org/2001/XMLSchema"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance">
<time>0001-01-01T01:01:01.001 0000-08:00</time>
<elapsedTicks>1 09210000000</elapsedTicks>
</Class1>

</Class1>
Thanks, I will use this! Looks like this is bug in FCL.
By the way can anyone explain me why .NET serializers store default property
values? Isn't it superflorous?

System.DateTime returns a string with the date and time. I want to convert
