How can I strip punctuation from a string?

Question

For the hope-to-have-an-answer-in-30-seconds part of this question, I\'m specifically looking for C#

But in the general case, what\'s the best way to strip punctuati

Answer 1

For long strings I use this:

var normalized = input
                .Where(c => !char.IsPunctuation(c))
                .Aggregate(new StringBuilder(),
                           (current, next) => current.Append(next), sb => sb.ToString());

performs much better than using string concatenations (though I agree it's less intuitive).
