If you want to include this code in your projects then you probably need to add a comment attributing it back to Facebook.NET -not sure what the open source license is on that project (but it should be OK as you'll be using Facebook.NET anyway)
Also, importantly.... unless you are updating an old project, my advice is do not use Facebook.NET - the FacebookToolkit from Microsoft (also on Codeplex) looks a much better way to go!
Here's the very longwinded code:

i suggest zipping this up because the code is completely unsuable in such way...i mean:

set

value = 0;
}
and
for (int i = 0; i <>
