Question

I need to define a regular expression that accepts Alphanumeric and the following special characters:
@#$%&*()-_+][‘;:?.,!

I’ve come up with:

string pattern = @"[a-zA-Z0-9@#$%&*+\-_(),+':;?.,![]\s\\/]+$";

But this doesn’t seem to be working. Can someone please let me know what is missing?

Answer 1

The [] in the middle need to be escaped*:

\[\]

You also probably want to anchor the start of the string with a ^.

_{* Probably just the ] but I like to do both for balance.}
