Yup. I'm sure someone initially thought it an immensely clever play on the 'C' programming language - but it introduced a lot of confusion owing to the world not being entirely ready for Unicode, and particularly not in programming languages that want to be portable.
Actually it is quite clever, and less a play on the 'C' programming than the 'C++' language. You can compose two plus characters into a hash symbol with just a little imagination, and a hash symbol looks pretty much like a sharp symbol, but C-sharp sounds much more interesting than C-hash. This is supported by the fact that Microsoft introduced a J++ language in the 90's, which was their implementation of Java with some interesting extensions, and that also led to a J# (J-sharp) around the same time as C#.
I don't recall it causing much confusion, but that discussion might take us too far off topic!
