Name

GroupCollection

Synopsis

This class is a collection of the captured groups in a regular expression. A GroupCollection is indexed by either a string with the name of the capture group, or with an integer number of the capture group as determined in the regular expression (give a name to a capture group by putting ?<name> immediately after the opening parenthesis). So, Match.Groups["name"] would retrieve a capture from the subexpression (?<name>expr), and Match.Groups[1] would be the result from the first explicitly grouped subexpression. The entire regular expression is the zero-indexed group (an expression without any groupings is treated as a single group). A GroupCollection is returned by Match.Groups.
