推荐答案

很复杂-但可能:

It''s complex - but possible:

^.*(?=.{8,10})(?=.*[!"£

％^& *()_] )(?=.* [a-zA-Z]).*

%^&*()_])(?=.*[a-zA-Z]).*

''和]''之间的字符是允许的特殊字符坦率地说，我不会为此使用正则表达式-我会在代码中这样做，它更易于维护.

The characters between the ''['' and '']'' are the permitted special characters. To be honest, I wouldn''t use a regex for this - I''d do it in code, it''s a lot more maintainable.
