title: Is there an easy way to append one IList<MyType> to another?
body: <p>Here is some sample code:</p>
  
  <pre><code>IList&lt;MyType&gt; myList1=new List&lt;MyType&gt;();
  IList&lt;MyType&gt; myList2=new List&lt;MyType&gt;();
  
  // Populate myList1
  ...
  // Add contents of myList1 to myList2
  myList2.Add(myList1); // Does not compile
  </code></pre>
  
  <p>How do I add the contents of one list to another - is there a method for this?</p>
