using NineDigit.SerialPort;

ISerialPortDeviceScanner deviceScanner = SerialPortDeviceScanner.Current;
IReadOnlyList<ISerialPortDevice> devices = deviceScanner.GetConnectedSerialPortDevices();

Console.WriteLine($"Detected {devices.Count} serial port device(s).");

for (int i = 0; i < devices.Count; i++)
{
    ISerialPortDevice device = devices[i];

    Console.WriteLine(
        $"{i + 1}. Product: {device.ProductName} (id = {device.ProductId}), " +
        $"Vendor: {device.VendorName} (id = {device.VendorId}), " +
        $"Port: {device.SerialPortName}");
}

Example output:
