Remove formatting from a string: “(123) 456-7890” => “1234567890”?

Question

I have a string when a telephone number is inputted - there is a mask so it always looks like \"(123) 456-7890\" - I\'d like to take the formatting out before saving it to the D

Answer 1

One possibility using linq is:

string justDigits = new string(s.Where(c => char.IsDigit(c)).ToArray());

Adding the cleaner/shorter version thanks to craigmoliver

string justDigits = new string(s.Where(char.IsDigit).ToArray())
