The Regex type exposes the following members.

  NameDescription
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Public method Static member Escape Escapes a minimal set of characters (\, *, +, ?, |, {, [, (,), ^, $,., #, and white space) by replacing them with their escape codes. This instructs the regular expression engine to interpret these characters literally rather than as metacharacters.
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
Public method GetGroupNames Returns an array of capturing group names for the regular expression.
Public method GetGroupNumbers Returns an array of capturing group numbers that correspond to group names in an array.
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method GroupNameFromNumber Gets the group name that corresponds to the specified group number.
Public method GroupNumberFromName Returns the group number that corresponds to the specified group name.
Public method IsMatch(String) Indicates whether the regular expression specified in the Regex constructor finds a match in the input string.
Public method IsMatch(String, Int32) Indicates whether the regular expression specified in the Regex constructor finds a match in the input string beginning at the specified starting position in the string.
Public method Static member IsMatch(String, String) Indicates whether the regular expression finds a match in the input string using the regular expression specified in the pattern parameter.
Public method Static member IsMatch(String, String, RegexOptions) Indicates whether the regular expression finds a match in the input string, using the regular expression specified in the pattern parameter and the matching options supplied in the options parameter.
Public method Static member IsMatch(String, String, RegexOptions, TimeSpan) Indicates whether the specified regular expression finds a match in the specified input string, using the specified matching options and time-out interval.
Public method Match(String) Searches the specified input string for the first occurrence of the regular expression specified in the Regex constructor.
Public method Match(String, Int32) Searches the input string for the first occurrence of a regular expression with a specified input string starting position.
Public method Static member Match(String, String) Searches the specified input string for the first occurrence of the regular expression supplied in the pattern parameter.
Public method Match(String, Int32, Int32) Searches the input string for the first occurrence of a regular expression with a specified input string starting position and input string length.
Public method Static member Match(String, String, RegexOptions) Searches the input string for the first occurrence of the regular expression supplied in a pattern parameter with matching options supplied in an options parameter.
Public method Static member Match(String, String, RegexOptions, TimeSpan) Searches the input string for the first occurrence of the specified regular expression, using the specified matching options and time-out interval.
Public method Matches(String) Searches the specified input string for all occurrences of a regular expression.
Public method Matches(String, Int32) Searches the specified input string for all occurrences of a regular expression, beginning at the specified starting position in the string.
Public method Static member Matches(String, String) Searches the specified input string for all occurrences of the regular expression specified in the pattern parameter.
Public method Static member Matches(String, String, RegexOptions) Searches the specified input string for all occurrences of the regular expression supplied in a pattern parameter with matching options supplied in an options parameter.
Public method Static member Matches(String, String, RegexOptions, TimeSpan) Searches the specified input string for all occurrences of a specified regular expression, using the specified matching options and time-out interval.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method Replace(String, String) Within a specified input string, replaces all strings that match a regular expression pattern with a specified replacement string.
Public method Replace(String, MatchEvaluator) Within a specified input string, replaces all strings that match a specified regular expression with a string returned by a MatchEvaluator delegate.
Public method Replace(String, String, Int32) Within a specified input string, replaces a specified maximum number of strings that match a regular expression pattern with a specified replacement string.
Public method Static member Replace(String, String, String) Within a specified input string, replaces all strings that match a specified regular expression with a specified replacement string.
Public method Static member Replace(String, String, MatchEvaluator) Within a specified input string, replaces all strings that match a specified regular expression with a string returned by a MatchEvaluator delegate.
Public method Replace(String, MatchEvaluator, Int32) Within a specified input string, replaces a specified maximum number of strings that match a regular expression pattern with a string returned by a MatchEvaluator delegate.
Public method Replace(String, String, Int32, Int32) Within a specified input substring, replaces a specified maximum number of strings that match a regular expression pattern with a specified replacement string.
Public method Static member Replace(String, String, String, RegexOptions) Within a specified input string, replaces all strings that match a specified regular expression with a specified replacement string. Specified options modify the matching operation.
Public method Static member Replace(String, String, MatchEvaluator, RegexOptions) Within a specified input string, replaces all strings that match a specified regular expression with a string returned by a MatchEvaluator delegate. Specified options modify the matching operation.
Public method Replace(String, MatchEvaluator, Int32, Int32) Within a specified input substring, replaces a specified maximum number of strings that match a regular expression pattern with a string returned by a MatchEvaluator delegate.
Public method Static member Replace(String, String, String, RegexOptions, TimeSpan) In a specified input string, replaces all strings that match a specified regular expression with a specified replacement string. Additional parameters specify options that modify the matching operation and a time-out interval if no match is found.
Public method Static member Replace(String, String, MatchEvaluator, RegexOptions, TimeSpan) In a specified input string, replaces all substrings that match a specified regular expression with a string returned by a MatchEvaluator delegate. Additional parameters specify options that modify the matching operation and a time-out interval if no match is found.
Public method Split(String) Splits the specified input string at the positions defined by a regular expression pattern specified in the Regex constructor.
Public method Split(String, Int32) Splits the specified input string a specified maximum number of times at the positions defined by a regular expression specified in the Regex constructor.
Public method Static member Split(String, String) Splits the input string at the positions defined by a regular expression pattern.
Public method Split(String, Int32, Int32) Splits the specified input string a specified maximum number of times at the positions defined by a regular expression specified in the Regex constructor. The search for the regular expression pattern starts at a specified character position in the input string.
Public method Static member Split(String, String, RegexOptions) Splits the input string at the positions defined by a specified regular expression pattern. Specified options modify the matching operation.
Public method Static member Split(String, String, RegexOptions, TimeSpan) Splits an input string into an array of substrings at the positions defined by a specified regular expression pattern. Additional parameters specify options that modify the matching operation and a time-out interval if no match is found.
Public method ToString Returns the regular expression pattern that was passed into the Regex constructor. (Overrides Object.ToString.)
Public method Static member Unescape Unescapes any escaped characters in the input string.
Protected method UseOptionR Infrastructure. Used internally by the regular expression engine.
