这将为数字工作在美国:
^ # beginning of string, or BOL in multi-line mode
(?:[+]?1[-. ]){0,1} # optional calling code, not captured
\(? # optional common prefix for area code, not captured
([2-9][0-8][0-9])? # optional NANP-allowed area codes, captured in $1
[)-. ]* # optional common delimiters after area code, not captured
( # begin capture group $2 for exchange code
[2-9] # first digit cannot be a 1
(?:[02-9][0-9]|1[02-9])) # second and third digit cannot be "11"
) # end capture group for exchange
[-. ]? # common delimiters between exchange and SN, not captured
([0-9]{4}) # subscriber number, captured in $3
(?: # start non-capturing group for optional extension
\s*(?:x|ext|ext.)\s* # common prefixes before extension numbers
(\d+) # optional extension, captured in $4
){0,1} # end non-capturing group
$ # end of string, or EOL in multi-line mode
这种处理电话代码(可选),半验证区号(可选)和交换码,分机号码(可选),并捕获每个部分的电话号码放在一个单独的变量中,以便于提取和操作。
使用.NET这个表情,你就需要包括IgnorePatternWhitespace和多标志等等逗号被忽略,^
和$
字符的字符串中的任何一行查找电话号码。
