Description
Contains a collection of groups from the most recent match with a regular expression.
A regular expression pattern can include subpatterns, which are defined by enclosing a portion of the regular expression pattern in parentheses. Every such subpattern captures a subexpression or group. For example, the regular expression pattern (\d{3})-(\d{2})-(\d{4}), which matches social security numbers. The first group consists of the first three digits and is captured by the first portion of the regular expression, (\d{3}). The second group of two digits is captured by the second portion of the regular expression, (\d{2}). And the third by (\d{4}). After a Match of a well formatted social security number with this regular expression, these three groups can then be retrieved from the TGroupCollection object that is returned by the Groups property.
