Regular Expression Language - Quick Reference
A regular expression is a pattern that the regular expression engine attempts to match in input text. A pattern consists of one or more character literals, operators, or constructs. For a brief introduction, see .NET Framework Regular Expressions.
Each section in this quick reference lists a particular category of characters, operators, and constructs that you can use to define regular expressions:
The backslash character (\) in a regular expression indicates that the character that follows it either is a special character (as shown in the following table), or should be interpreted literally. For more information, see Character Escapes in Regular Expressions.
Escaped character | Description | Pattern | Matches |
|---|---|---|---|
\a | Matches a bell character, \u0007. | \a | "\u0007" in "Error!" + '\u0007' |
\b | In a character class, matches a backspace, \u0008. | [\b]{3,} | "\b\b\b\b" in "\b\b\b\b" |
\t | Matches a tab, \u0009. | (\w+)\t | "item1\t", "item2\t" in "item1\titem2\t" |
\r | Matches a carriage return, \u000D. (\r is not equivalent to the newline character, \n.) | \r\n(\w+) | "\r\nThese" in "\r\nThese are\ntwo lines." |
\v | Matches a vertical tab, \u000B. | [\v]{2,} | "\v\v\v" in "\v\v\v" |
\f | Matches a form feed, \u000C. | [\f]{2,} | "\f\f\f" in "\f\f\f" |
\n | Matches a new line, \u000A. | \r\n(\w+) | "\r\nThese" in "\r\nThese are\ntwo lines." |
\e | Matches an escape, \u001B. | \e | "\x001B" in "\x001B" |
\ nnn | Uses octal representation to specify a character (nnn consists of two or three digits). | \w\040\w | "a b", "c d" in "a bc d" |
\x nn | Uses hexadecimal representation to specify a character (nn consists of exactly two digits). | \w\x20\w | "a b", "c d" in "a bc d" |
\c X \c x | Matches the ASCII control character that is specified by X or x, where X or x is the letter of the control character. | \cC | "\x0003" in "\x0003" (Ctrl-C) |
\u nnnn | Matches a Unicode character by using hexadecimal representation (exactly four digits, as represented by nnnn). | \w\u0020\w | "a b", "c d" in "a bc d" |
\ | When followed by a character that is not recognized as an escaped character in this and other tables in this topic, matches that character. For example, \* is the same as \x2A, and \. is the same as \x2E. This allows the regular expression engine to disambiguate language elements (such as * or ?) and character literals (represented by \* or \?). | \d+[\+-x\*]\d+\d+[\+-x\*\d+ | "2+2" and "3*9" in "(2+2) * 3*9" |
A character class matches any one of a set of characters. Character classes include the language elements listed in the following table. For more information, see Character Classes in Regular Expressions.
Character class | Description | Pattern | Matches |
|---|---|---|---|
[ character_group ] | Matches any single character in character_group. By default, the match is case-sensitive. | [ae] | "a" in "gray" "a", "e" in "lane" |
[^ character_group ] | Negation: Matches any single character that is not in character_group. By default, characters in character_group are case-sensitive. | [^aei] | "r", "g", "n" in "reign" |
[ first - last ] | Character range: Matches any single character in the range from first to last. | [A-Z] | "A", "B" in "AB123" |
. | Wildcard: Matches any single character except \n. To match a literal period character (. or \u002E), you must precede it with the escape character (\.). | a.e | "ave" in "nave" "ate" in "water" |
\p{ name } | Matches any single character in the Unicode general category or named block specified by name. | \p{Lu} \p{IsCyrillic} | "C", "L" in "City Lights" "Д", "Ж" in "ДЖem" |
\P{ name } | Matches any single character that is not in the Unicode general category or named block specified by name. | \P{Lu} \P{IsCyrillic} | "i", "t", "y" in "City" "e", "m" in "ДЖem" |
\w | Matches any word character. | \w | "I", "D", "A", "1", "3" in "ID A1.3" |
\W | Matches any non-word character. | \W | " ", "." in "ID A1.3" |
\s | Matches any white-space character. | \w\s | "D " in "ID A1.3" |
\S | Matches any non-white-space character. | \s\S | " _" in "int __ctr" |
\d | Matches any decimal digit. | \d | "4" in "4 = IV" |
\D | Matches any character other than a decimal digit. | \D | " ", "=", " ", "I", "V" in "4 = IV" |
Anchors, or atomic zero-width assertions, cause a match to succeed or fail depending on the current position in the string, but they do not cause the engine to advance through the string or consume characters. The metacharacters listed in the following table are anchors. For more information, see Anchors in Regular Expressions.
Assertion | Description | Pattern | Matches |
|---|---|---|---|
^ | The match must start at the beginning of the string or line. | ^\d{3} | "901" in "901-333-" |
$ | The match must occur at the end of the string or before \n at the end of the line or string. | -\d{3}$ | "-333" in "-901-333" |
\A | The match must occur at the start of the string. | \A\d{3} | "901" in "901-333-" |
\Z | The match must occur at the end of the string or before \n at the end of the string. | -\d{3}\Z | "-333" in "-901-333" |
\z | The match must occur at the end of the string. | -\d{3}\z | "-333" in "-901-333" |
\G | The match must occur at the point where the previous match ended. | \G\(\d\) | "(1)", "(3)", "(5)" in "(1)(3)(5)[7](9)" |
\b | The match must occur on a boundary between a \w (alphanumeric) and a \W (nonalphanumeric) character. | \b\w+\s\w+\b | "them theme", "them them" in "them theme them them" |
\B | The match must not occur on a \b boundary. | \Bend\w*\b | "ends", "ender" in "end sends endure lender" |
Grouping constructs delineate subexpressions of a regular expression and typically capture substrings of an input string. Grouping constructs include the language elements listed in the following table. For more information, see Grouping Constructs in Regular Expressions.

You can specify options that control how the regular expression engine interprets a regular expression pattern. Many of these options can be specified either inline (in the regular expression pattern) or as one or more RegexOptions constants. This quick reference lists only inline options. For more information about inline and RegexOptions options, see the article Regular Expression Options.
You can specify an inline option in two ways:
By using the miscellaneous construct (?imnsx-imnsx), where a minus sign (-) before an option or set of options turns those options off. For example, (?i-mn) turns case-insensitive matching (i) on, turns multiline mode (m) off, and turns unnamed group captures (n) off. The option applies to the regular expression pattern from the point at which the option is defined, and is effective either to the end of the pattern or to the point where another construct reverses the option.
By using the grouping construct (?imnsx-imnsx:subexpression), which defines options for the specified group only.
The .NET Framework regular expression engine supports the following inline options.
Option | Description | Pattern | Matches |
|---|---|---|---|
i | Use case-insensitive matching. | \b(?i)a(?-i)a\w+\b | "aardvark", "aaaAuto" in "aardvark AAAuto aaaAuto Adam breakfast" |
m | Use multiline mode. ^ and $ match the beginning and end of a line, instead of the beginning and end of a string. | For an example, see the "Multiline Mode" section in Regular Expression Options. | |
n | Do not capture unnamed groups. | For an example, see the "Explicit Captures Only" section inRegular Expression Options. | |
s | Use single-line mode. | For an example, see the "Single-line Mode" section in Regular Expression Options. | |
x | Ignore unescaped white space in the regular expression pattern. | \b(?x) \d+ \s \w+ | "1 aardvark", "2 cats" in "1 aardvark 2 cats IV centurions" |
Miscellaneous constructs either modify a regular expression pattern or provide information about it. The following table lists the miscellaneous constructs supported by the .NET Framework. For more information, see Miscellaneous Constructs in Regular Expressions.
Construct | Definition | Example |
|---|---|---|
(?imnsx-imnsx) | Sets or disables options such as case insensitivity in the middle of a pattern. For more information, see Regular Expression Options. | \bA(?i)b\w+\b matches "ABA", "Able" in "ABA Able Act" |
(?# comment) | Inline comment. The comment ends at the first closing parenthesis. | \bA(?#Matches words starting with A)\w+\b |
# [to end of line] | X-mode comment. The comment starts at an unescaped # and continues to the end of the line. | (?x)\bA\w+\b#Matches words starting with A |
