title: C# shift an array of byte
body: <p>I want to compute this : <code>tab&lt;&lt;1</code> with tab an array of byte</p>
  
  <p>I do these few lines but it seems that it does not work. I'm I doing something wrong?</p>
  
  <pre><code>byte[] T = new byte[16];
  
  
  for (int i = 0; i &lt; 16; i++) T[i] = (byte)(tab[i] &lt;&lt; 1);
  </code></pre>
