XmlTextReader and 2GB file limit

[Hugh McFadden]

Are there any work arounds to get XmlTextReader to work with files bigger
than 2GB? I tried to get the source of XmlTextReader and create a version
with long (instead of int) offsets but I can't compile it due to package
restrictions.

Best wishes,
Hugh McFadden

Sorry for lame question, I've never tried to process so enourmous documents,
but what's the problem exactly is? Do you get any exception or something?

Yes, you're right, I get this exception:
System.IndexOutOfRangeException:

Hmmm, it's too few info. In Rotor sources I don't see nothing in
SetElementValues method which could cause IndexOutOfRangeException, probably
it happens deeper in XmlScanner.
It's tempting to debug it under Rotor, but the file is so huge I cannot
download it at work, only at home in the evening.
Which .NET version are you using?

I am using v1.1 of the framework on Win2k3.

I think it is this particular line:
int offset = _Scanner.StartPos;

When the file is bigger than 2GB then that line will assign -1 to offset
(atleast I think, without being able to debug it I can't be sure)
