上述标准可以是什么？
我正在创建一个更强密码的检查:)
c#我正在使用
这应该这样做：
(?=.*?[a-z])(?=.*?[A-Z])(?=.*?[^a-zA-Z]).{8,}
见：rubular
解释：
(?=.*?[a-z]) //lookahead,there has to be a lower case alphabetic char
(?=.*?[A-Z]) //lookahead,there has to be a upper case alphabetic char
(?=.*?[^a-zA-Z]) //lookahead,there has to be a non-alphabetic char
.{8,} // any character at least 8 times
