Other Exceptions
For the SqlDataReader implementation, GetString will throw an exception if the value is null. When implementing this method, is it suggested/required to follow this pattern? A class that I am working on is going to implement this interface, and for now I think I will stick to this precendent since consumers of the class may expect it.

Also throws exception for invalid cast
The documentation only lists one exception, but bear in mind that this also throws an exception if it can't cast the field as a string. I got the following error in my code:
[Unable to cast object of type 'System.Int16' to type 'System.String'.]
That's pretty annoying actually, since I would have thought the GetString method could handle an Int16 object, but anyway, be aware.
