如何自定义有效的正则表达式 - 电话号码

how to customize the valid Regex with - into phone number

推荐答案

这取决于你想要的严格程度，看起来这个正则表达式并不是特别严格。
这个正则表达式说：

well it depends on how strict you want to be it doesn't seem like this regex is especially strict. this regex says:

1. 从行首开始


2. 匹配一个 + （或者可能是1或0）似乎
   不明确（但可能不依赖于实现），因为
   捕获括号： （）分解 \ + 和的关系？


3. 可能放错地方：


4. 匹配任何数字 0-9 1或0次6-14次


5. 然后一位 0-9


6. 然后结束。

1. start at beginning of line
2. match one + (or maybe 1 or 0) which seems ambiguous (but may not be depending on implementation) because the capture parentheses:() breaks up the relationship of the \+ and the ?
3. possibly misplaced :
4. match any digit 0-9 1 or 0 times 6-14 times
5. then one digit 0-9
6. then end of line.

你还注意到任何反斜杠都必须加倍...... @\\b用于单词边界。
您可能想尝试类似......

also you note that any backslash will have to be doubled... @"\\b" for a word boundary. you may want to try something like...

@"\\b[\\d]{3}\\-[\\d]{3}\\-[\\d]{4}\\b"
would I think match your example, but it wouldn't match
(555) 555 - 5555 or
555.555.5555 or
