title: Converting an array of 2 consecutive bytes to integers faster
body: <p>I have a 'huge' amount of data, which may vary between 50 and 100 MegaBytes.
  I read this data in as an array of bytes using a filestreamer.</p>
  
  <p>The thing is, I want to convert all consecutive 2 bytes into an integer.
  The way I do this is I loop through the array of bytes with a stepsize of two, and then use BitConvert to do the conversion:</p>
  
  <pre><code>_data[i] = BitConverter.ToInt16(soundData[i : i + 2], 0) // Convert 2 bytes into an int and store at i
  </code></pre>
  
  <p>So each two bytes get turned into an Int16.
  The problem however, is that this is too slow, as for a file of about 50 megabytes this can take up 20 seconds!</p>
  
  <p>Is there a generic way of doing this instantly, instead of calling this function on each 2 bytes of my data array such that it isn't that slow? Preferably in a 'safe' way, so no unsafe code.</p>
