 |`(?("")("".+?(?<!\\)""@)`|If the first character is a quotation mark, match a beginning quotation mark followed by at least one occurrence of any character, followed by an ending quotation mark. The ending quotation mark must not be preceded by a backslash character (\\). `(?<!` is the beginning of a zero-width negative lookbehind assertion. The string should conclude with an at sign (@).|  
 |<code>&#124;(([0-9a-z]</code>|If the first character is not a quotation mark, match any alphabetic character from a to z or A to Z (the comparison is case insensitive), or any numeric character from 0 to 9.|  
 |`(\.(?!\.))`|If the next character is a period, match it. If it is not a period, look ahead to the next character and continue the match. `(?!\.)` is a zero-width negative lookahead assertion that prevents two consecutive periods from appearing in the local part of an email address.|  
-|<code>&#124;[-!#\$%&'\*\+/=\?\^\`{}\&#124;~\w]</code>|If the next character is not a period, match any word character or one of the following characters: -!#$%'*+=?^\`{}&#124;~.|

 |`(?<=[0-9a-z])`|Continue the match if the character that precedes the @ character is A through Z, a through z, or 0 through 9. The `(?<=[0-9a-z])` construct defines a zero-width positive lookbehind assertion.|  
 |`(?(\[)`|Check whether the character that follows @ is an opening bracket.|
