title: How to use GroupBy in LINQ with ranges of numbers?
body: <p>Is it possible to use GroupBy in Linq to group by ranges of numbers?  For instance if I have a large table of data, and want it to be grouped by say 0-20, 21-40, 41-60, 61-80, 81-100.  </p>
  
  <p>Is that possible and if so how would I accomplish that?</p>
