help with Contains method

Question

I'm trying to detect if a string contains any characters outside of a range of values (ASCII) from (comma) to |(pipe). I tried this and it didnt work string.Contains([^-|]); any ideas?

Contains() looks for a substring not for appearances of any of those characters individually. IndexOfAny() should work but since it takes a char array instead of a string you'll need to do an extra function call like this: string textToEvaluate = ABCDEF[GHIJ; string badChars = [^-|]; int i = textToEvaluate.IndexOfAny(badChars.ToCharArray()); If none of the bad chars are in the string to be evaluated i = -1 otherwise it will contain the position of the first bad char.
