This method sends an N-GET request, using the quoted SOP Class and Instance UIDs.  The values of the attributes in the DataSet are irrelevant, as it is used solely as a list of attributes whose values are to be retrieved.
The returned values may be found, once the operation has completed, in the ReturnedDataSet property.
