title: String replace, remove fastest way
body: <p>I'm reading with html agility pack a forum message into a string (~120 words). </p>
  
  <p>From this string i want to remove the quote (~30 words). The quote is also available as string and it always stands at the beginning of the message.</p>
  
  <p>So what do you think will be the fastest way to achive this?
  (before this substraction, i already cleanup the strings from special characters using regex to replace e.g. &quot; with ""\")</p>
  
  <p>As far as i can see i have various options: string.replace, stringbuilder.replace, regex.replace? What about counting the words (length of quote is known ) and remove them from original string?</p>
  
  <p>Any comment is welcome :-)</p>
  
  <p>Thanks, 
   Ralf  </p>
