I have followed a example from a book exactly, but it seems not working at
all.
can anyone tell me what is going on?


========= Global.asax.cs ============

public static Entry LoadEntry(String filename)
{
//construct the path
String filepath = XMLFilePath + "\\" + filename;
FileStream f = null;
Entry newEntry;

try
{
//open the file
f = new FileStream(filepath,FileMode.Open);

//create a serializer...
XmlSerializer serializer = new XmlSerializer(typeof(Entry));
newEntry = (Entry)serializer.Deserialize(f);
}
finally
{
//close the file
f.Close();
}
//retrun the entry..
return newEntry;
}


====== default.aspx.cs =======

//loading entry from xml file
Entry entry = Global.LoadEntry("address.xml");
this.lblCatalog.Text = entry.Catalog;
this.lblName.Text = entry.Name;
this.lblAddress.Text = entry.Address;

===== address.xml ========

Pei,

It looks like the error is actually in your xml document itself.
