Question

I am not a regex guy, so I need a little help, just cant get my head around this…

I am writing registration page and using asp.net validators. I need a regex validator to match a special character anywhere within a word, so it will satisfy requirement which says that “ID must have at least one special character.” Allowed characters are:
! ” # $ % & ‘ ( ) * + , –
. / : ; < = > ? @ [ \ ] ^
_ ` { | } ~

Once again, I am a junior, and having problems with wrapping my head around this stuff at this moment…

For now I have

[\[\]\^\$\.\|\?\*\+\(\)\\~`!@#%&-_+={}'""<>:;, ]{1,}

but it matches numbers as well for some reason, and sometimes don’t match characters in the beginning of the word…

So, please, if anyone could help me with that…

Answer 1

You need to escape ‘-‘ and ‘!’

[\[\]\^\$\.\|\?\*\+\(\)\\~`\!@#%&\-_+={}'""<>:;, ]{1,}
