Answer 1

A slight extension on the answer offered by Pedro:

Regex.Replace(Name, @"(?:(M|m)(c)|(\b))([a-z])", delegate(Match m) { 
    return String.Concat(m.Groups[1].Value.ToUpper(), m.Groups[2].Value, m.Groups[3].Value, m.Groups[4].Value.ToUpper());
 });

This will correctly capitalize McNames in addition to title case. eg "simon mcguinnis" --> "Simon McGuinnis"

• The first non-capture group will match any word-break character OR "Mc" / "mc".
• If it matches a word-break, then groups 1 and 2 are empty and group 3 contains that character.

• If it matches "Mc" or "mc" the groups 1 and 2 contain "m" and "c" and group 3 is empty.

  • Group 1 (the "m" or "M") is capitalized.
  • Group 2 (the "c") remains un-altered.
  • Group 3 (the break character) remains un-altered.
  • Group 4 (the first letter of the next word) is capitalized.

All 4 groups, empty or otherwise, are concatenated to generate the return string.
