title: How to convert a byte to a char, e.g. 1 -> '1'?
body: <p>How to convert a byte to a char? I don't mean an ASCII representation.
  I have a variable of type <code>byte</code> and want it as a character.</p>
  
  <p>I want just following conversions from byte to char:<br>
  0 ->'0'<br>
  1 ->'1'<br>
  2 ->'2'<br>
  3 ->'3'<br>
  4 ->'4'<br>
  5 ->'5'<br>
  6 ->'6'<br>
  7 ->'7'<br>
  8 ->'8'<br>
  9 ->'9'  </p>
  
  <p><code>(char)1</code> and <code>Convert.ToChar(1)</code> do not work. They result in <code>''</code> because they think <code>1</code> is the ASCII code.</p>
