Is C# a low-level language?

I’m a massive fan of everything Fabien Sanglard does, I love his blog and I’ve read both his books cover-to-cover (for more info on his books, check out the recent Hansleminutes podcast). Recently he wrote an excellent post where he deciphered a postcard sized raytracer, un-packing the obfuscated code and providing a fantastic explanation of the maths involved. I really recommend you take the time to read it! But it got me thinking, would it be possible to port that C++ code to C#?
