How to Index into

The XLINQ query in VB9:
Expand|Select|Wrap|Line Numbers
  1.  Dim studentGrades = _
  2.     From r In grades _
  3.     Where r...<AssignedTo>.Value = sd.sID _
  4.     Order By r...<DateCompleted>.Value Ascending _
  5.     Select r...<AssignmentGrade>.Value, r...<DateCompleted>.Value
  6.  
returns a variable of type System.Collection.Generic.IEnumerable( Of <anonymous type>).

How do you index into such a Collection? You can Enumerate over the Collection with For Each. You can get the studentGrades.Count. But how do you easily get access to the Last value, for instance?

All help is appreciated.
