C# Regular Expression to find multiple sequences of punctuation characters

Question

I'm trying to match punctuations using regular expressions.

Do I have to specify every punctuation character I am searching for or is there is an escape sequence I can use?

I'm sitting here smiling to myself that the answers I might get will just be "Yes" or "No", please elaborate.... (that sentence should match the regular expression twice)

You don't need to specify all sub-categories, since the `\p{P}` category includes all of them – Thomas Levesque Apr 30 '10 at 01:27

That would be a character class, not an escape sequence. You can use a character class defined by a Unicode category :

\p{P}

This expression matches characters in the category "All Punctuation". You can find a list of supported categories in the UnicodeCategory enumeration
