You can look up the Session instance by SessionID (which is passed to you
in the OnCreate, FromApp, FromAdmin, and OnMessage callbacks):

Session session = Session.LookupSession(sessionID);


And then you can access the DataDictionary properties of the Session:

DataDictionary.DataDictionary sessionDataDict =
session.SessionDataDictionary;
DataDictionary.DataDictionary appDataDict =
session.ApplicationDataDictionary;


If you are using FIX.4.4 or earlier, there's only one DataDictionary, so
SessionDataDictionary and ApplicationDataDictionary point to the same
instance.  Separate DataDictionaries are only used with FIXT sessions (i.e.
FIX.5.0 and later).
