If so, use MatchObj.Value to get the contents of the match, MatchObj.Length for the length of the match, and MatchObj.Index for the start of the match in the subject string. MatchObj.Success indicates if there actually was a match.

If not, use the static version: Dim MatchObj as Match = Regex.Match('subject', 'regex').Д®ither way, you will get an object of class Match that holds the details about the first regex match in the subject string. If you instantiated a Regex object, use Dim MatchObj as Match = RegexObj.Match('subject'). If you want more information about the regex match, call Regex.Match() to construct a Match object. All these methods accept an optional additional parameter of type RegexOptions, like the constructor. Regex.Split('subject', 'regex') splits the subject string into an array of strings as described above. Regex.Replace('subject', 'regex', 'replacement') performs a search-and-replace. Regex.IsMatch('subject', 'regex') checks if the regular expression matches the subject string. All the static methods have the same names (but different parameter lists) as other non-static methods. Note that member overloading is used a lot in the Regex class.

This reduces the amount of code you have to write, and is appropriate if the same regular expression is used only once or reused seldomly. The Regex class also contains several static methods that allow you to use regular expressions without instantiating a Regex object. If you want the entire regex matches to be included in the array, simply place parentheses around the entire regular expression when instantiating RegexObj. If the regex contains capturing parentheses, the text matched by them is also included in the array. The array contains the text between the regex matches. RegexObj.Split('Subject') splits the subject string along regex matches, returning an array of strings. Improper use of the $ sign may produce an undesirable result string, but will never cause an exception to be raised.

NET Framework 1.x compared with later versions. There are a few differences between the regex flavor in the. There are no differences between this flavor and the flavor supported by any version of. There are no differences in the regex flavor supported by the. The only noteworthy features that are lacking are possessive quantifiers and subroutine calls.
