title: ToCharArray equivalent for List<string>
body: <p>How do you split a string to a List? I'm looking for the equivalent of ToCharArray but instead to make it a List.</p>
  
  <pre><code>string data = "ABCDEFGHIJ1fFJKAL";
  List&lt;string&gt; datalist = new List&lt;string&gt;();
  datalist.AddRange(new List&lt;string&gt;{"A","B","C"});
  </code></pre>
  
  <p>How do you convert data so it will be accepted by AddRange?</p>
