使用 C# 判斷有那些 Serial Port

    
    SerialPort ComPort = new SerialPort();
    string[] ports = SerialPort.GetPortNames();
    foreach(string portName in ports)
    {
        ComPort.PortName = portName;
        ComPort.BaudRate = 115200;
        ComPort.Parity = Parity.None;
        ComPort.StopBits = StopBits.One;
        ComPort.ReadTimeout = 500;
        ComPort.WriteTimeout = 500;
        try
        {
            ComPort.Open();
            ...
        }
        catch
        {
            ComPort.Close()
         
        }
    }
