IEnumerable Or Enumerable for Enumerating composite objects
<p>Hello I need some help with the following:</p>

<p>I have a ListView control with many ListViewItems, and each ListViewItem's tag property references a domain object like Customer etc.</p>

<p>when retrieving the collection of selected listviewItems, I would like to pass an <code>IEnumerable&lt;Customer&gt;</code> instead of the <code>IEnumerable&lt;ListViewItem&gt;</code> to a function to do something with it.</p>

<p>what would be the best way to achieve this with only one loop?</p>

<p>Thanks.</p>
