title: Convert byte[] to sbyte[]
body: <p>I tried to convert an Array from <code>byte[]</code> to <code>sbyte[]</code>.</p>
  
  <p>Here is my sample Array:</p>
  
  <pre><code>byte[] unsigned = { 0x00, 0xFF, 0x1F, 0x8F, 0x80 };
  </code></pre>
  
  <p>I already tried this:</p>
  
  <pre><code>sbyte[] signed = (sbyte[])((Array)unsigned);
  </code></pre>
  
  <p>But it doesn't work. There is no value in the array after this operation.</p>
  
  <p>Does anybody has an better idea?</p>
