title: How to add an item to an IEnumerable
body: <p>In C#</p>
  
  <pre><code>IEnumerable&lt;MyModel&gt; test = _blah.tolist();
  </code></pre>
  
  <p>Now I can loop through test, but how do I add an item?</p>
  
  <p>Please do not tell me that it makes no sense to add an item, I've already seen that post. </p>
  
  <p>What I want to know is, if I loop through 10 items, how do I put one more on so it loops through 11 items?</p>
  
  <p>Also there is no .Add() method </p>
