collectionbase derived class and XmlAttribute

[Dirk Reske]

Hello,

I've created a collection.

public class MyCollection:CollectionBase
{
public int Version;

[...]
}

I want to serialize it...and it works!
but what do I have to do, that the XmlSerializer serializes the Version
property also?

thx

IIRC the XmlSerializer doesn't serialize fields, just public properties.
Wrap it.

Are you marking your class as serializable? Your extension won't inherit the
attribute.

yes,

here the top of my class:
[Serializable]
public class Contacts:System.Collections.CollectionBase
{
private int version = 0;

[XmlAttribute("Version")]
public int Version
{
get { return this.version; }
set { this.version = value; }
}

[...]
}

but the XmlSerializer doesn't serialize the Version Property

The XmlSerializer does *never* serialize properties of collection classes,
just the content is serialized. You have to move the Version propery to
another class, probably the class containing the collection property.

Example (shown as Xml):
<parent>
<items>
<item />
<item />
<item />
</items>
<version>1.0.0.0</version>
</parent>
