Strange problem with XmlSerializer creating duplicate end tags

[sklett]

I have several objects that I'm saving to disk via the XmlSerializer. 80% of
the time this works fine, but occasionaly it will create a file like this:

<?xml version="1.0"?>
<SystemOptions xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<AssetDirectory>C:\Documents and Settings\sklett\Local
Settings\Temp\</AssetDirectory>
<ProductLabelPrinter>Adobe PDF</ProductLabelPrinter>
</SystemOptions>
</SystemOptions>

Note the double </SystemOptions> tags. Anyone ever run into this?

Here is the code doing the serialization in case it helps:
<code>

public void Save()
{
using (FileStream stream = File.Open(FullPath,
FileMode.OpenOrCreate, FileAccess.Write))
{
_serializer.Serialize(stream, this);
stream.Close();
}
}

</code>

Thanks for reading,

It sounds to me like the second tag was left-overs from the file
contents previous... i.e. you have over-written part of the file
(only).

Have you tried deleting the file first and starting from fresh?

Deleting is a good idea, I never thought of that. I haven't used
XmlSerialization much and when I have it always works so well (too easy
maybe) that I just figured it would "take care of everything and work
perfect"

I've added code to delete the file first, hopefully that solves it, makes
sense that it would.
Thanks for the suggestion!

XmlSerializer is doing its job just fine; FileStream is the culprit
