System.Text.RegularExpressions Namespace

Provides regular expression functionality that may be used from any platform or language that runs within .NET. In addition to the types contained in this namespace, the RegexStringValidator class enables you to determine whether a particular string conforms to a regular expression pattern.

Classes

Capture	Represents the results from a single successful subexpression capture.
CaptureCollection	Represents the set of captures made by a single capturing group. The collection is immutable (read-only) and has no public constructor.
GeneratedRegexAttribute	Instructs the System.Text.RegularExpressions source generator to generate an implementation of the specified regular expression.
Group	Represents the results from a single capturing group.
GroupCollection	Returns the set of captured groups in a single match. The collection is immutable (read-only) and has no public constructor.
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. The collection is immutable (read-only) and has no public constructor. The Matches(String) method returns a MatchCollection object.
Regex	Represents an immutable regular expression.
RegexCompilationInfo	Provides information about a regular expression that is used to compile a regular expression to a stand-alone assembly.
RegexMatchTimeoutException	The exception that is thrown when the execution time of a regular expression pattern-matching method exceeds its time-out interval.
RegexParseException	An exception as a result of a parse error in a regular expression, with detailed information in the Error and Offset properties.
RegexRunner	The RegexRunner class is the base class for compiled regular expressions.
RegexRunnerFactory	Creates a RegexRunner class for a compiled regular expression.

Structs

Regex.ValueMatchEnumerator	Represents an enumerator containing the set of successful matches found by iteratively applying a regular expression pattern to the input span.
Regex.ValueSplitEnumerator	Represents an enumerator containing the set of splits around successful matches found by iteratively applying a regular expression pattern to the input span.
ValueMatch	Represents the results from a single regular expression match.

Enums

RegexOptions	Provides enumerated values to use to set regular expression options.
RegexParseError	Specifies the detailed underlying reason why a RegexParseException is thrown when a regular expression contains a parsing error.

Delegates

MatchEvaluator

Represents the method that is called each time a regular expression match is found during a Replace method operation.
