XML deserialization problem

[David Preuss]

Hi all,

i have a problem with a class which has several subclasses embedded when
trying to deserialize it.

Serializing works just fine. The xml is as follows:

<?xml version="1.0" encoding="utf-8" ?>
<Project xmlns:xsd="http ://www.w3.org/2001/XMLSchema"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance" ProjectName="Te st
Project">
<CreationDate>2 005-03-22T16:07:50.355 6672+01:00</CreationDate>
<XmlSourceDocum ents>
<XmlSourceDocum ent>
<CreationDate>2 005-03-22T16:07:50.355 6672+01:00</CreationDate>
<DocumentName>D oc 1</DocumentName>
</XmlSourceDocume nt>
<XmlSourceDocum ent>
<CreationDate>2 005-03-22T16:07:50.355 6672+01:00</CreationDate>
<DocumentName>D oc 1</DocumentName>
</XmlSourceDocume nt>
<XmlSourceDocum ent>
<CreationDate>2 005-03-22T16:07:50.355 6672+01:00</CreationDate>
<DocumentName>D oc 1</DocumentName>
</XmlSourceDocume nt>
</XmlSourceDocume nts>
</Project>

The underlying class looks like this:

{
public class Project
{
public Project()
{
m_alSourceDocum ents = new ArrayList();
}

private ArrayList m_alSourceDocum ents;
private string m_sProjectName;
private DateTime m_dtCreationDat e;
private StylesheetRepos itoryItem m_oStylesheetRe positoryItem;

public StylesheetRepos itoryItem StyleSheet
{
get { return m_oStylesheetRe positoryItem; }
set { m_oStylesheetRe positoryItem = value; }
}

public DateTime CreationDate
{
get { return m_dtCreationDat e; }
set { m_dtCreationDat e = value; }
}

public string ProjectName
{
get { return m_sProjectName; }
set { m_sProjectName = value; }
}

public int Add(XmlSourceDo cument in_oSourceDoc)
{
return m_alSourceDocum ents.Add(in_oSo urceDoc);
}

public void AddRange(XmlSou rceDocument[] in_arSourceDocR ange)
{
m_alSourceDocum ents.AddRange(i n_arSourceDocRa nge);
}

public void Remove(XmlSourc eDocument in_oSourceDocum ent)
{
m_alSourceDocum ents.Remove(in_ oSourceDocument );
}

public void RemoveAt(int index)
{
m_alSourceDocum ents.RemoveAt(i ndex);
}

public void Clear()
{
m_alSourceDocum ents.Clear();
}

public void Insert(int index, XmlSourceDocume nt in_oSourceDocum ent)
{
m_alSourceDocum ents.Insert(ind ex,in_oSourceDo cument);
}

public int Count
{
get { return m_alSourceDocum ents.Count; }
}

public XmlSourceDocume nt[] XmlSourceDocume nts
{
get { return
(XmlSourceDocum ent[])m_alSourceDocu ments.ToArray(t ypeof(XmlSource Document));
}
set {}
}

public void SaveProject(str ing path)
{
lock(path)
{
if(File.Exists( path))
File.Delete(pat h);
XmlSerializer xsr = new XmlSerializer(t ypeof(Project)) ;
FileStream fs = new
FileStream(path ,FileMode.Creat e,FileAccess.Wr ite,FileShare.R ead);
XmlTextWriter xtw = new XmlTextWriter(f s,System.Text.E ncoding.UTF8);
xtw.Formatting = Formatting.Inde nted;
try
{
xsr.Serialize(x tw,this);
}
catch(Exception ex)
{
}
finally
{
xtw.Close();
}
}
}

public static Project LoadProject(str ing path)
{
XmlSerializer xsr = new XmlSerializer(t ypeof(Project)) ;
FileStream fs = File.OpenRead(p ath);
Project cs = (Project)xsr.De serialize(fs);
fs.Close();
return cs;
}
}
}

The problem is that when i try to deserialize the xml file the
XmlSourceDocume nt Array has the length of 0. So the XmlSourceDocume nt
nodes beeing not deserialized.

Can someone help with this? I somehow suspect my approach using an
ArrayList beeing not correct.

Thanks in advance,

David
