Represents the method that is called each time a regular expression match is found during a Replace method operation.
Assembly: System (in System.dll)
Return ValueType: System.String
A string returned by the method that is represented by the delegate.
You can use a delegate method to perform a custom verification or manipulation operation for each match found by a replacement method such as Regex.Replace(String, MatchEvaluator). For each matched string, the Replace method calls the 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 method substitutes for the matched string.
