正则表达式至少8个上下数字或其他非字母

>至少包含8个字符.

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
