推荐答案

您应该有一个（工作）线程进行串口通信。反过来，这样的线程会将适当接收的数据发送到适当的GUI控件（参见如何：对Windows窗体控件进行线程安全调用 [ ^ ]）。它也可以从GUI控件获取输入，以便将它们发送到串口。

You should have a single (working) thread for serial port communication. Such thread in turn, would dispatch apporpriately received data to the proper GUI control (see How to: Make Thread-Safe Calls to Windows Forms Controls[^]). It would as well get input from the GUI controls in order to send them to the serial port.
