I'm parsing OSM XML data into c#.

I have a weird problem, each node has an id that is a long datatype. When parsing, if the id is 9 or less digits long, it seems to work just fine. However once it reaches 10 digits long, for some reason I start to get negative number from the parsing. Is there a reason for why this might be.

I'm using a library called OSMSharp for parsing. Language is c#.

An example of this: This way has 2 nodes:

way id="313281300" 
nd ref="248877110"
nd ref="3191908562"*

After being parsed, I get this:

way: 313281300

248877110

-1103058734

Could this be a bug from the parsing library, or is it caused by c#?

Thank you in advance

*I made this xml short for ease of read. It's the full xml for the way in the file I'm parsing from

Are you sure you are using the latest version of OSMSharp and long definitions throughout? It looks like it is having problems relayed to http://wiki.openstreetmap.org/wiki/64-bit_Identifiers

this might be it actually. The only problem is the newer versions of OSMSharp don't support parsing. I will investigate further. Thanks
