xmlSerializer & xmlAttrbuteOverrides of arrays

Normally I would add attributes to the class to help the XmlSerializer to
deserialize the data which I've included below:

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

public class XmlDeserializationDemo
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
private static void Main(string[] args)
{
Bead b = Deserialize(@"..\..\Bead.xml");
PrintBead(b);
}

private static void PrintBead(Bead b)
{
Console.WriteLine("Bead BeadID = {0}", b.BeadID);
foreach(Point point in b.Points)
{
Console.WriteLine("\tPoint x={0} y={1}", point.X, point.Y);
}
}

private static Bead Deserialize(string fileName)
{
XmlTextReader reader = new XmlTextReader(fileName);
XmlSerializer serializer = new XmlSerializer(typeof(Bead));
return serializer.Deserialize(reader) as Bead;
}
}

[XmlRoot("BeadType", Namespace="", IsNullable=false)]
public class Bead
{
private Point[] m_points;
private double m_id;

public Bead()
{
}

[XmlAttribute("BeadID")]
public double BeadID
{
get { return m_id; }
set { m_id = value; }
}

[XmlElement("Point")]
public Point[] Points
{
get { return m_points; }
set { m_points = value; }
}
}

public class Point
{
private string m_x;
private string m_y;

public Point()
{
}

public Point(string x, string y)
{
this.X = x;
this.Y = y;
}

[XmlAttribute("X")]
public string X
{
get { return m_x; }
set { m_x = value; }
}

[XmlAttribute("Y")]
public string Y
{
get { return m_y; }
set { m_y = value; }
}
}

Hope that helps

Dear all,

I have a set of c# data classes which i need to fill their data from xml
files. serialization looks to be the best way to accomplish this task.
Since the data classes are compiled and i don't have control on the xml
structure, I tried using the xmlAttributeOverrides class, to instruct the
serializer.
I was able to override the attributes for the root element, but I'm having
problems understanding how to deserialize arrays.

I would be delitaed if you could take a look at the code, and try to figure
out what's wrong there.

Dear all,

I have a set of c# data classes which i need to fill their data from
xml
files. serialization looks to be the best way to accomplish this task.
Since the data classes are compiled and i don't have control on the
xml
structure, I tried using the xmlAttributeOverrides class, to instruct
the
serializer.
I was able to override the attributes for the root element, but I'm
having
problems understanding how to deserialize arrays.

I would be delitaed if you could take a look at the code, and try to
