mixed XML serialization

[andrewcw]

I have an object that serializes back and forth.
I would like to have some objects not serialize ..and when
I read that info back into the class, have this item be
null ( or something like it ).

I modified a class I made by XSD.exe by adding these
values ( drvltr, disknum) , but I found when I wrote the
class out to file and retrieved it, the values were
persisted.

If this is reasonable, how do I approach it ? Thanks

In the example below, the tool inserts the declaration
[System.Xml.Seri alization.XmlAt tributeAttribut e()]
for each attribute. Therefore I added the the attributes
drvltr and disknum because I reasoned maybe without the
declaration, they would be ignored.

[System.Xml.Seri alization.XmlAt tributeAttribut e()]
public string uniqueid;
public string drvltr;
public string disknum;
