xmlSerializer & xmlAttrbuteOver rides of arrays

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 xmlAttributeOve rrides 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.

Thanks in advance,
Zion.

The data class to be deserialized:
public class Bead
{
private Point[] m_points;
private double m_id;

public Bead(){}

public double BeadID
{
get{return m_id;}
set{m_id = value;}
}

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;
}

public string X
{
get {return m_x;}
set {m_x = value;}
}

public string Y
{
get {return m_y;}
set {m_y = value;}
}
}

The input xml:
<BeadType BeadID="17"><Po int ID="1" X="1" Y="0.02026"/><Point ID="2" X="2"
Y="0.02172"/><Point ID="3" X="3" Y="0.0233"/></BeadType>

The deserializing function:

private void button1_Click(o bject sender, System.EventArg s e)
{
FileStream fs = new FileStream(txtF ile.Text, FileMode.Open);
XmlReader reader = new XmlTextReader(f s);

Type type = typeof(Bead);

XmlAttributeOve rrides attOverrides = new XmlAttributeOve rrides();

//Define the root element in the XML
XmlAttributes beadAtts = new XmlAttributes() ;
beadAtts.XmlRoo t = new XmlRootAttribut e("BeadType") ;
attOverrides.Ad d(type, beadAtts);

//
XmlAttributes beadIdAtts = new XmlAttributes() ;
XmlAttributeAtt ribute beadIDAtt = new XmlAttributeAtt ribute();
beadIDAtt.DataT ype = "double";
beadIDAtt.Attri buteName = "BeadID";
beadIdAtts.XmlA ttribute = beadIDAtt;
attOverrides.Ad d(type, "BeadID", beadIdAtts);
XmlAttributes atts = new XmlAttributes() ;
//XmlArrayAttribu te aa = new XmlArrayAttribu te("Point");
//atts.XmlArray = aa;
//attOverrides.Ad d(type, "Points", atts);

XmlArrayItemAtt ribute pointArrayItem = new XmlArrayItemAtt ribute();
pointArrayItem. ElementName = "Point";
pointArrayItem. DataType = "Point";
atts.XmlArrayIt ems.Add(pointAr rayItem);
attOverrides.Ad d(typeof(Point) , "Points", atts);

XmlSerializer serializer = new XmlSerializer(t ype, attOverrides);

object obj = serializer.Dese rialize(reader) ;
reader.Close();

}

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.Seri alization;

public class XmlDeserializat ionDemo
{
/// <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.WriteLi ne("Bead BeadID = {0}", b.BeadID);
foreach(Point point in b.Points)
{
Console.WriteLi ne("\tPoint x={0} y={1}", point.X, point.Y);
}
}

private static Bead Deserialize(str ing fileName)
{
XmlTextReader reader = new XmlTextReader(f ileName);
XmlSerializer serializer = new XmlSerializer(t ypeof(Bead));
return serializer.Dese rialize(reader) as Bead;
}
}

[XmlRoot("BeadTy pe", Namespace="", IsNullable=fals e)]
public class Bead
{
private Point[] m_points;
private double m_id;

public Bead()
{
}

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

[XmlElement("Poi nt")]
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

Thanks for your reply.

I'm sorry if I wasn't clear enough.
I don't want to add attributes in my class code. I only want to deserialize
the Xml using Attribute Overrides.
This way I don't need to re-compile my data classes with each change to the
XML (Which I don't have any control of).

Thanks,
Zion.

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.

Hi I've been reading using the XmlSerializer with custom collections. I've discovered that when serializing a custom collection (a class that implements ICollection, IList etc.) the XmlSerializer will only serialize the collection items - with the default root as ArrayofMyItems etc. My custom collection class has some additional public properties that I would like to include in the serialization above the items element array (in

Before I continue, I'm going to begin by saying I'm not by any means an expert- I've been using .NET with C# for about 4 months now, and basically just learning by example and docs. A game project I work on uses Xml serialization to store game objects for loading. One of the techniques we use is to make an array property and use the set block to perform actions on the values after they're loaded from the xml, as in: public string Ids

I've just read Christoph Schittko's article on XmlSerializer: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnxmlnet/html/trblshtxsd.asp . . . and very informative it is too. I, too, am getting nasty FileNotFound exceptions. I've read, and digested the article, and I think I've found a bug -- it's difficult to track, though it does happen often.

Hi, I've hit quite a strange problem with XmlSerializer on my W2K3 server. When I serialize/deserialize using an exe on my local computer (XP), everything works fine. When I put the code out on the server (W2K3) it throws an exception. It only seems to happen when serializing/deserializing _arrays_ of a type. If I just serialize/deserialize one instance, it works fine. The exception I get is: (sorry for the word wrapping.)...

Hi! I am currently trying to learn C#, and have started by developinga simple messaging application with a client and server. Byusing callback delegates, I can asynchronously send and recievetext as byte arrays. Because I wanted to be able to send more advanced messagesbetween the client and server, I decided to create my ownmessage class, serialize it, and deserialize it at the other end(using XmlSerializer). Now to my question: ...

I'm using XMLSerializer to serialize a hierarchy of class-based objects to XML. So far, this is working successfully by employing arrays to handle the multiplicity of child objects. However, I'm trying to employ the use of collection classes instead because there are methods I need to implement at that level. But when I instantiate the XMLSerializer, it gives the error: There was an error reflecting <Root Type>. If I try using ...

Hi, I want to send XML data from a server to some clients over a network connection using the TCP/IP protocol. If I send the XMLs as byte arrays I need to insert header information in the data to distinguish the XMLs from each other in the stream of data. Is there any way to avoid this (for instance by sending SOAP telegrams))? I have tried using the XMLSerializer.Serialize(stream) to serialize the XML telegrams and send them over the...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
