The problem must be in the wrapper class you are using, C# only has a notion of System.IO.Ports.SerialPort. Here you can use GetPortNames (static method) to get the ports currently available on your system.
See for more info: SerialPort Class [^]

If it's in your project, then you can store what ever you want in variables and use it afterwards.

I'd suggest using only one SerialPort instance. Set the PortName once and then use references to the same SerialPort instance every time you need to send or receive something.

I can only agree with your comment; data sources always need to have a McCloud attitude :). There shall be only one!

Having two ways of retrieving the same information can (and will) lead to ambiguity... ehhh errors in case you might misunderstand...
