title: Converting string to int[]
body: <p>I was wondering how I could convert numbers in a string value to an <code>int[]</code>.
  I have the following numbers stored in a string:</p>
  
  <pre><code>1,2,3,4
  </code></pre>
  
  <p>But I was wondering how I could get these numbers stored in an <code>int[]</code> so each value is stored into the <code>int</code> array.</p>
