title: How do I perform a dynamic select in Linq?
body: <p>I am trying to figure out how to dynamically specify the properties for my select clause in a linq query.  </p>
  
  <p>Lets say I have a collection of employee objects.  At run time, the end user will be specifying which properties they would like to see for those employees, so I need to be able to dynamically construct my Linq select clause.</p>
  
  <p>I have used the dynamic Linq library, but I prefer not to use that, because it requires me to build a string to pass to the select method.  I'd like to understand how to do this via Expressions.</p>
