title: Regex.Replace unable to make it work
body: <p>I would expect following code to replace every occurence of whitespace+digit+whitespace but it is replacing anything+digit+anything.</p>
  
  <pre><code>nswapfirstpart = Regex.Replace(nswapfirstpart, "\W[0-9]\W", " _ ")
  </code></pre>
  
  <p>Thanks</p>
