serialize a property of a collection

Hi,
I have a collection, which is a property of a class:
public class PostcodeCollection : CollectionBase
{
    // ...collection specific properties
    [XmlAttribute("Total")]
    public int Total
    {
        get { return List.Count; }
        set {}
    }
}

The main class is:
[XmlRoot("PostCodes" )]
public class PostcodeReport
{
    // ..other properties
    [XmlArray("Updated")]
    [XmlArrayItem(typeof(PostCodeLine), ElementName="PostCode")]
    public PostcodeCollection Updated
    {
        get { return this.updated; }
    }
}

I want to add the "Total" property as an attribute to "Updated" node.
Using "XmlAttribute" on the property, doesn't do the trick.

This is how the xml must look like:
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type='text/xsl' href='PostcodeUpdates.xslt'?>
<PostCodes Generated="03-05-2007, 17:50">
<Added />
<Updated Total="23" >
    <PostCode District="2031"... />
</Updated>
</PostCodes>

How can i do this?

Many thanks,
Daniel

See this blog entry:

XmlSerialization with IDictionary and CollectionBase Objects
http://sholliday.spaces.live.com/blog/

It may or may not help.

I just know xml serialization gets finicking on CollectionBase (IDictionary)
objects.

thanks, but not much help.
using the model from your link or that from http://www.mattberther.com/?p=52
requires that i serialize manually each collection.
and this is too much, i have already 4 collections in my report and other
might come in.

i'm shocked anyway that for such a simple task i have to do things
manually...

Are you saying you can't create a wrapper.

class MyReportInfo
(with these members)
    PeopleCollection
    StateCollection
    CountyCollection

and serialize that one (wrapper) object?

//Matt Quote
The drawback is that I have to have a container class, as these attributes
can't be applied to a class. Not necessarily my first choice, but, I suppose
it will do.
