When you enter the loop shortestPath.Length equals zero, doesn't it?
You will never find a lower value in s.Length.

Ooops! Sorry!. This is what happens when I type a piece of code out of
memory without testing it, and I concentrate on a different aspect of the
code (the fact that it was copying references instead of copying the
strings).
A couple of solutions have already been proposed in other messages:
Either use an int to represent the length and preload it with int.MaxValue,
or preload the shortestPath with an existing path from the array.

I appreciate you taking the time to reply.
