title: How to get the value of the discrimiator from a TPH collection in EF4?
body: <p>I have an abstract parent entity with 6 inherited child entities, using TPH in EF4.</p>
  
  <p>Is there a simple way to get the value of the dicriminator column, bearing in mind that although at the moment it is the same as the Type.Name, this does not have to be the case.</p>
  
  <p>In my case, I am importing data from many sources into a single table for processing - so the <strong>Disc</strong> is very useful so I only have one table, which I can expand to take in many sources.</p>
  
  <p>I'd like to be able to simply loop through the collection and get the value of the discriminator - I would have thought that should be possible/sensible?</p>
