The following example illustrates the use of the IsMatch(String, String) method to determine whether a string is a valid part number. The regular expression assumes that the part number has a specific format tha
if (match.Success) { // Part 4: get the Group value and display it. string key = match.Groups[1].Value; Console.WriteLine(key); } alternate-1 Start, end matching. We can use metacharacters to match the start and end of strings. This is often done when using regular expressions. Use...
Regex()andRegex Match()match a pattern in a given string but return different results. To transforms your string into another string, useRegex(). To identify the substrings that match specific parts of the pattern, useRegex Match(). This example shows the efficiency ofRegex Match()compared t...
The following example illustrates the use of the IsMatch(String, String) method to determine whether a string is a valid part number. The regular expression assumes that the part number has a specific format that consists of three sets of characters separated by hyphens. The first set, which ...

In a specified input string, replaces all substrings that match a specified regular expression with a string returned by a MatchEvaluator delegate. Additional parameters specify options that modify the matching operation and a time-out interval if no match is found. Replace(String, String, MatchEv...
Regex to NOT match string Though there is no special regular expression syntax for not matching a specific string, you can emulate this behavior by using anegative lookahead. Supposing you wish to find strings thatdo not containthe word "lemons". This regular expression will work a treat: ...
