title: Collection<PSObject> to CSV output
body: <p>Is there a nice  way to convert <code>Collection&lt;PSObject&gt;</code> to CSV output?</p>
  
  <pre><code>Collection&lt;PSObject&gt; psResult = pipeline.Invoke();
  </code></pre>
  
  <p>Tried <code>pipeline.ToCsv();</code>
  Also <code>psResult.ToCsv()</code></p>
  
  <p>Any ideas?</p>
