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?

Thanks to all of you! (And Mainly Jon!): This allowed me to write this:

    private static readonly char[] Punctuation = "$€£".ToCharArray();

    public static bool IsPrice(this string text)
    {
        return text.IndexOfAny(Punctuation) >= 0;
    }

as I was searching for a good way to detect if a certain string was actually a price or a sentence, like 'Too low to display'.
