title: Entity Framework providing column names as string variable
body: <p>I'm looking for way to get something like this:</p>
  
  <pre><code>string _col1 = "first name";
  string _name;
  var query = from c in ctx.Customers select c;
  _name = query.FirstOrDefault().[_name];
  </code></pre>
  
  <p>As far as I can see I can only get strongly typed field names but I would like to provide them as string variables.</p>
