All jar files in the folder in the folder. (This step is wrong, it should be DLL file, which has been corrected here)

OCI.DLL (renamed by 'oci.dll.dbl')

Oracle.dataaccess.dll
Oraciicus11.dll
Oraops11w.dll
Olannzsbb11.dll
Oracci11.dll
OCIW32.dll (renamed by 'OCIW32.dll.dbl')
Paste the duplicated DLL file into a folder containing the C#executable file.

5. After completing these steps, it will ensure that all the necessary components are available, thereby solving the compatibility problem of the ODP.NET version, and the successful Oracle database connection and data retrieval.
