sha-256 multiple updates

Question

I am trying to duplicate the java md.update(digest) functionality using the .net SHA256Managed Class.  Each time I execute the java md.update(digest) the hash output changes (even though the value of digest stays the same).  With the .net application, calling the method ComputHash(Byte()), yields the same output each time the call is made.  The output should change each time the call is made.  Any ideas on how to make the .net function like the java?
