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

Describes intent, easiest to read (IMHO) and best performing:

 s = s.StripPunctuation();

to implement:

public static class StringExtension
{
    public static string StripPunctuation(this string s)
    {
        var sb = new StringBuilder();
        foreach (char c in s)
        {
            if (!char.IsPunctuation(c))
                sb.Append(c);
        }
        return sb.ToString();
    }
}

This is using Hades32's algorithm which was the best performing of the bunch posted.
