I hope this helps you . With this regex you will have to trim a trailing space from the results:
  [0-9A-E][0-9A-F]      A hex digit excluding "F", followed by a hex digit
  |                     or
  [0-9A-F][0-9A-E]      A hex digit, followed by a hex digit excluding "F"
 \s?                    an optional space
)+                      The whole pattern repeated at least once
string pattern = @"(([0-9A-E][0-9A-F]|[0-9A-F][0-9A-E])\s?)+";
var matches = Regex.Matches(input, pattern);
foreach (var match in matches) {
string pattern = "[0-9A-E][0-9A-F]|[0-9A-F][0-9A-E]";
var matches = Regex.Matches(input, pattern);
foreach (var match in matches) {

Writing regular expression

I wish did fix the issue. Do the brackets belong to the expression? Can you give an example, please.
Maybe the following regex works already:
Pattern pattern = Pattern.compile("F_[ES]_[A-Za-z0-9]+_[A-Za-z0-9]+");
Matcher matcher = pattern.matcher(myStringToMatch);
if (matcher.matches())
  // Yeah, Baby!

Url re-writing regular expression

help you fix your problem no idea about Asp.net, but the regexp was tested with grep. you could try in your .net box:
kent$  cat a
kent$  grep -P "(^fr-ca$|^\d+$|^(fr-ca|\d+)/(\w|\d*)$)" a
or ^\d+$
or ^(fr-ca|\d+)/(\w|\d*)$

the above line can be broken down as well
  ^(fr-ca|\d+)/(\w|\d*)$ :

starting with fr-ca or \d+
then comes "/"
after "/" we expect \w or \d*
then $(end)

should help you out One way to re-write the regexp to enhance readability (to reduce the chance to count consecutive whitespaces):
^( {4})*#(\s.*\S)?$
