Thanks.

Actually organising the write up forced me to tidy up the code much more than I otherwise would have. I definitely find C# to be one of the more readable languages although I have had to debug and untangle some C# messes before.

Yeah I remember changing it to a SortedDictionary but I changed it back. I can't remember exactly why, possibly because it's supposed to be sorted by raw UTF8 bytes rather than a nice neat C# string and I didn't want to start using byte arrays for dictionary keys. I guess it only needs to be sorted when in the BEncoding format and it felt better to keep the internal structure as simple as possible. The tradeoff is it doesn't support incorrectly encoded torrent files – I'm really not sure how much of an issue that is.
