C# Regex Match Evaluator issue

[kadono]

I'm attempting to write some code to make all the tags in my webapp lowercase.

Currently I'm using a regex pattern with a match evaluator to do this, but it's not working and gives me some strange errors.

Okay, here's my regex pattern (which works):

builder = new StringBuilder(Regex.Replace(builder.ToString(),@"(?<=<)[/]{0,1}\w+[^>]",new MatchEvaluator(ToLowerEval)));
 

Now here's the match evaluator:

private static String ToLowerEval(Match m)
      {
         string match =  m.Value;
         return match.ToLower();
      }

This fails silently, but when I step through with Visual Studio and use the Immediate Command area, I get this:

match.ToLower()
error: 'match.ToLower' does not exist

This happens when I use any of the String functions. Any one know why or have a better way of solving this?
