... Did you really read the Haskell code ?
You're comparing two completely unrelated algorithms, talk about a
fair comparison !

Maybe a reading of
http://en.literateprograms.org/Sieve_of_Eratosthenes_(Haskell) would
help you ?
Note that you C# code algorithm could be written in Haskell quite
compactly, it would already be a better match !
