Anyone who is good with Arduino and C# please help:

I am trying to communicate an Arduino with C#. I am having trouble with the button to create a serial port and the button to close the serial port.

I have attached a picture of what I have done, but it does not work.

Instructions:

-One button that creates a serial port Object and opens the relevant COM port.

-Another button that closes the port.

-When the port is open, turn on a Green LED, and off when the port is closed.
