title: convert EnumerableRowCollection<string> to List<string>
body: <p>I am trying to return this collection in a function:</p>
  
  <pre><code>List&lt;string&gt; codes = ( from q in Data.AsEnumerable() select q.Field&lt;string&gt;("START") );
  return codes;
  </code></pre>
  
  <p>This throws error:</p>
  
  <pre><code>Cannot implicitly convert type 'System.Data.EnumerableRowCollection&lt;string&gt;' to 'System.Collections.Generic.List&lt;string&gt;'
  </code></pre>
  
  <p>What's the best way to return such a collection?</p>
