Looks like this has been answered here already.

The solution was:

var result = Regex.Replace(
"The allergy type a1c should be written A1C.", // input
@"a1c",                                        // word to match
@"<b>$0</b>",                                  // "wrap match in bold tags"
RegexOptions.IgnoreCase);                      // ignore case when matching
