(probably the best - see the second answer) http://bytes.com/topic/c-sharp/answers/277768-regex-convert-camelcase-into-title-case

To convert from UpperCamelCase to Title Case, use this line : Regex.Replace("UpperCamelCase",@"(\B[A-Z])",@" $1");

To convert from both lowerCamelCase and UpperCamelCase to Title Case, use MatchEvaluator : public string toTitleCase(Match m) { char c=m.Captures[0].Value[0]; return ((c>='a')&&(c<='z'))?Char.ToUpper(c).ToString():" "+c; } and change a little your regex with this line : Regex.Replace("UpperCamelCase or lowerCamelCase",@"(\b[a-z]|\B[A-Z])",new MatchEvaluator(toTitleCase));
