title: Regex to find and replace a year in a string
body: <p>I have a string in my c#:</p>
  
  <blockquote>
    <p>The.Big.Bang.Theory.(2013).S07E05.Release.mp4</p>
  </blockquote>
  
  <p>I need to find an occurance of <code>(2013)</code>, and replace the whole thing, including the brackets, with <em>_</em> (Three underscores). So the output would be:</p>
  
  <blockquote>
    <p>The.Big.Bang.Theory.<em>_</em>.S07E05.Release.mp4</p>
  </blockquote>
  
  <p>Is there a regex that can do this? Or is there a better method?</p>
  
  <p>I then do some processing on the new string - but later, need to report that '(2013)' was removed .. so I need to store the value that is replaced.</p>
