XmlSerializer and defaults

[dmonder]

I am using the XMLSerializer to map the XML below to an object as
follows:

Config config
XmlSerializer xmls = new XmlSerializer( typeof( Config ) );
try {
TextReader tr = new StreamReader( "config.xml" );
config = (Config)xmls.Deserialize( tr );
tr.Close();
} catch (System.IO.FileNotFoundException) {
// How do I set up the defaults??
}

My problem is that I want to be able set my config object to defaults
if the xml file is not found. Any ideas?

----- XML File -----

<?xml version="1.0"?>

config = new Config();
config.Property1 = defaultForProperty1;
// etc.

For example :
You can read from default xml from resources.
or
You can directly set the default values
config = new Config();
confic.variables = defaultValue;
}
or define Config with pre-set default values.
