...but I can't help thinking that the way that C# handles strings is
inefficient.

Göran Andersson commented: "to allocate and release objects is faster
in a garbage collected environment than in a traditional heap that
uses reference counters."

OK, but in C, I would only allocate the string once, and it would be
a fixed-length string of 41 characters (max num characters is 40 plus
one extra character for the null terminator). I wouldn't keep
allocating it and de-allocating it - I would use it repeatedly, and
if I'm using it a million times in a for loop, then surely this would
be much much faster than what C# does, since it doesn't need to be
allocated and de-allocated each time. Or am I missing something here?

Yes - what's involved in allocating 40 characters. On the managed heap,
that involves increasing a pointer by 80 bytes, checking whether or not
it's exceeded the boundaries of the generation, and (assuming it
hasn't) zeroing out the memory. It's not a lot of work.
