I'm currently maintaining a Visual Basic project that makes use of tnsping. In order to do a tnsping, it uses a ProcessStartInfo instance to make the call as if it were using the command prompt(DOS). I was wondering if a library exists (Oracle.DataAccess maybe?) or if there's something built into the .NET libraries that will allow me to do the tnsping without the ProcessStartInfo. Could anyone point me in the right direction? Thanks in advance for all of your answers.
