Connect to an Oracle database

Question

I\'m trying to connect to an Oracle database but when the the code is executing the line:

con = new OracleConnection(oradb);

It gives this erro

Answer 1

I was getting that error in my test project. The problem was that I was opening Visual Studio from a command line that had an old PATH. After opening everything fresh, it worked.

Check the PATH from your code, and make sure the oracle folder is in the PATH.
