title: BitArray - Shift bits
body: <p>I have a System.Collections.BitArray array (~3000 items) and I would like to shift all the bits to the left by 1. However the collection doesn't seem to support that operation (i.e. bitArray &lt;&lt; 1 not working and there is no method). Any idea on how to do that?</p>
  
  <p>Thanks!</p>
