Should a directory path variable end with a trailing slash?

Question

When defining a path to a directory as a variable or constant, should it end with a trailing slash? What is the convention?

Answer 1

Whenever I store directory paths or return them from APIs, I try and stick with the convention of keeping a trailing slash. This avoids the whole 'is it a file or a directory' ambiguity.

Addendum:
This is not intended to be a substitute for using methods that can tolerate either a trailing slash or its absence. Even using this convention I still always use Path.Combine(...) and similar methods.
