title: C# Reactive Extensions - Iterate through items of IObservable<List<Item>>
body: <p>I've started to play around with the <code>rx</code> version of <strong>C#</strong> recently and am wondering how it's possible to solve the following problem:</p>
  
  <p>I'm using <a href="https://github.com/paulcbetts/refit" rel="nofollow">refit</a> to get a list of items from a server via:</p>
  
  <pre><code>[Get("/items")]
  IObservable&lt;List&lt;Item&gt;&gt; GetItems();
  </code></pre>
  
  <p>I would like to process each item afterwards, but I didn't find out how to do that. I know in RxJava there is an operator called <code>flatMapIterable()</code> which allows me to process each item, but I didn't find something similar for <strong>C#</strong>.</p>
  
  <p>Thanks </p>
