Regular Expression to limit all letters less than 100 characters

I need the regular expression that would limit the number of characters to 100 and allow the use of 0-9, !@.,;:'"?- and all lower and uppe开发者_运维技巧r case letters

^(.{1,100})$

. This will allow all the characters numbers and special characters also {1,100} this the range you need to specific like min and max count

/^[0-9A-Za-z!@.,;:'"?-]{1,100}\z/

Depends on the language, but should be

^[0-9A-Za-z!@\.;:'"?-]{1,100}$

As pointed out in comments, and just to avoid usage of bad example:

^[0-9A-Za-z!@.,;:'"?-]{1,100}\z
