I think you want something like this instead:
(defn GetSubfolderName [filename]
(let [name-wo-extn (Path/GetFileNameWithoutExtension filename)
first-char (aget (.ToCharArray (.ToString name-wo-extn)) 0)]
(if (Char/IsDigit first-char) (Convert/ToInt32 first-char)
(if (starts-with-hmorx first-char) (.ToLower (.ToString first-char))
"other"))))
The nested if is a little unusual though. I would probably rewrite it
to use cond. If you can get a repl going, try to step through each
expression and see where the problem is that way. I don't have
Clojure .NET set up to give a more precise answer unfortunately.
