Classes

	Class	Description
	Capture	Represents the results from a single subexpression capture. Capture represents one substring for a single successful capture.
	CaptureCollection	Represents a sequence of capture substrings. CaptureCollection returns the set of captures done by a single capturing group.
	Group	Group represents the results from a single capturing group. A capturing group can capture zero, one, or more strings in a single match because of quantifiers, so Group supplies a collection of Capture objects.
	GroupCollection	Represents a collection of captured groups. GroupCollection returns the set of captured groups in a single match.
	Match	Represents the results from a single regular expression match.
	MatchCollection	Represents the set of successful matches found by iteratively applying a regular expression pattern to the input string.
	Regex	Represents an immutable regular expression.
	RegexCompilationInfo	Provides information that the compiler uses to compile a regular expression to a stand-alone assembly.
	RegexRunner	The RegexRunner class is the base class for compiled regular expressions.
	RegexRunnerFactory	Creates a RegexRunner class for a compiled regular expression.
