For connection with the oracle first thing you need is the ODP(oracle data provider) download it and after that add reference to the following assembly

C#

Oracle.DataAccess.dll.

rest of your code seems to be ok.

For detailed explanation please check on the following link-->Connecting to Oracle Database through C#? - Stack Overflow[^]
