Remarks

You can use a MatchEvaluator delegate method to perform a custom verification or manipulation operation for each match found by a replacement method such as Replace(String, MatchEvaluator). For each matched string, the Replace(String, MatchEvaluator) method calls the MatchEvaluator delegate method with a Match object that represents the match. The delegate method performs whatever processing you prefer and returns a string that the Replace(String, MatchEvaluator) method substitutes for the matched string.
