C# serial port to obtain more detailed information device description, PID, VID
C# provides a standard serial library. How to obtain the serial port list is not discussed here. However, it does not provide a method to obtain more serial port information. It cannot obtain detailed information such as device description, PID, VID, etc., as shown above: Without further ado, here’s the code: public struct PORT_INFO { […]
