title: how to set a value of char array to null?
body: <p>for example when I wrote:</p>
  
  <pre><code>Char[] test = new Char[3] {a,b,c};
  test[2] = null;
  </code></pre>
  
  <p>it says <strong>Cannot convert null to 'char' because it is a non-nullable value type</strong></p>
  
  <p>if I need to empty that array of char, is there a solution?</p>
