here's the documentation for the regular reader, from Python 2.5:

     reader(...)
         csv_reader = reader(iterable [, dialect='excel']
                                 [optional keyword args])
             for row in csv_reader:
                 process(row)

         The "iterable" argument can be any object that returns a line
         of input for each iteration, such as a file object or a list.
         ...

so the reader is simply looping over the characters in your filename.  try

     r = csv.DictReader(open('C:\Temp\Book1.csv'))

instead.
