How to build this pattern?

A string cannot include any of these symbols: ^ ~ \ & -- % | “ [ ] : ;
= * ? > < #

if (Regex.IsMatch(someString, pattern))
MessageBox.Show("A string cannot include any of these symbols: ^ ~
\ & -- % | “ [ ] : ; = * ? > < #")

Do you have to do it with regular expressions? I mean, it's feasibly -
but using string.IndexOfAny is simpler.

string t = @"^ ~ \ & -- % | “ [ ] : ;> = * ? > < #";
Pattern = "^[" + t + "]+?";

Regex.IsMatch(someString, t)

A string cannot include any of these symbols: ^ ~ \ & -- % | “ [ ] : ;

= * ? > < #

if (Regex.IsMatch(someString, pattern))
   MessageBox.Show("A string cannot include any of these symbols: ^~
\ & -- % | “ [ ] : ; = * ? > < #")

try pattern "\\^|~|\\|&|--|%|\\||\"|\\[|\\]|:|;|=|>|<|#"

then
if (! Regex.IsMatch(someString, pattern))
MessageBox.Show("A string cannot include any of these
symbols: ^ ~ \ & -- % | “ [ ] : ; = * ? > < #")
