RegEx:英国固定电话、手机号码

Question

我一直在努力寻找合适的解决方案:-

我需要一个匹配所有英国电话号码和手机的正则表达式。

到目前为止，这似乎涵盖了英国的大部分数字:

^0\d{2,4}[ -]{1}[\d]{3}[\d -]{1}[\d -]{1}[\d]{1,4}$

但是，手机号码不适用于此正则表达式或写在单个实心块中的电话号码，例如 01234567890。

谁能帮我创建所需的正则表达式？

Answer 1

这个正则表达式可以吗？

//// Split the InputText wherever the regex matches
// string[] results = MyRegex.Split(InputText);

请注意空格和破折号是可选的，并且可以成为其中的一部分。此外，它现在分为两个捕获组，称为 area_code 和 tel_no 以将其分解并更容易提取。
