Check if a string contains one of 10 characters

Question

I\'m using C# and I want to check if a string contains one of ten characters, *, &, # etc etc.

What is the best way?

Answer 1

The following would be the simplest method, in my view:

var match = str.IndexOfAny(new char[] { '*', '&', '#' }) != -1

Or in a possibly easier to read form:

var match = str.IndexOfAny("*&#".ToCharArray()) != -1

Depending on the context and performance required, you may or may not want to cache the char array.
