Regex Methods

The Regex type exposes the following members.

  Name Description
Public method Static member CompileToAssembly(RegexCompilationInfo[], AssemblyName) Compiles one or more specified Regex objects to a named assembly.
Public method Static member CompileToAssembly(RegexCompilationInfo[], AssemblyName, CustomAttributeBuilder[]) Compiles one or more specified Regex objects to a named assembly with the specified attributes.
Public method Static member CompileToAssembly(RegexCompilationInfo[], AssemblyName, CustomAttributeBuilder[], String) Compiles one or more specified Regex objects and a specified resource file to a named assembly with the specified attributes.
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 it 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 the default hash function. (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.
Protected method InitializeReferences Infrastructure. Used by a Regex object generated by the CompileToAssembly method.
Public method IsMatch(String) Indicates whether the regular expression specified in the Regex constructor finds a match in a specified input string.
Public method IsMatch(String, Int32) Indicates whether the regular expression specified in the Regex constructor finds a match in the specified input string, beginning at the specified starting position in the string.
Public method Static member IsMatch(String, String) Indicates whether the specified regular expression finds a match in the specified input string.
Public method Static member IsMatch(String, String, RegexOptions) Indicates whether the specified regular expression finds a match in the specified input string, using the specified matching options.
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, beginning at the specified starting position in the string.
Public method Static member Match(String, String) Searches the specified input string for the first occurrence of the specified regular expression.
Public method Match(String, Int32, Int32) Searches the input string for the first occurrence of a regular expression, beginning at the specified starting position and searching only the specified number of characters.
Public method Static member Match(String, String, RegexOptions) Searches the input string for the first occurrence of the specified regular expression, using the specified matching options.
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 a specified regular expression.
Public method Static member Matches(String, String, RegexOptions) Searches the specified input string for all occurrences of a specified regular expression, using the specified matching options.
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) In a specified input string, replaces all strings that match a regular expression pattern with a specified replacement string.
Public method Replace(String, MatchEvaluator) In 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) In 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) In 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) In 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) In 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) In 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) In 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) In 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) In 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.
