title: Add byte to array removes capitalized letters
body: <p>I try to add a byte to an array as shown below:</p>
  
  <pre><code>messagedata.Add((byte)0xF0);
  </code></pre>
  
  <p>But then when I check the array, the item looks like 0xf0 but it since it's going to be a MIDI message I found it has to be a capital F. What can I do to keep the letters capitalized?</p>
