SybaseHelper class?

Question

I am trying to connect to sybase ASE 15 and call a SP that does some DML. I was wondering if anyone has any pointers to a sybase helper class analogous to SQLhelper.cs or if someone has any pointers to any blog / sample code.

Eventually I will be migrating the solution to SQl Server 2008 R2 (couple of months from now) so I want to create a generic implementation which can be used without much change even after migration.

--Calling it this way will invoke the expliciti garbage Collection

using (ISybaseDBHelper _DBHelper = ObjectFactory.GetDBHelper())

                _DBHelper.InsertDataUsingStoredProcedure("usp_load_fx_spot_rate_into_staging", DatabaseEnum.Staging, input);
