推荐答案

不，你不知道.

您真正想要做的是处理SerialPort DataRecieved消息，并在到达每个字节时对其进行处理，或者将它们传输到缓冲区以在后台进行处理.

如果您尝试连续阅读，则会锁定UI并惹恼您的用户...

No, you don''t.

What you actually want to do is handle the SerialPort DataRecieved messages, and process each byte as it arrives, or transfer them to a buffer for processing in the background.

If you try to read continuously, you will lock up your UI and annoy your users...

CP上有一些类似的应用程序-搜索并浏览它们.这是一个入门的指南: CSerialIO-有用且简单的串行通信类 [ ^ ]

您标记了C ++，所以这是我在此处添加的示例.如果您感兴趣，C#中还有其他不错的项目.

There are several applications like that here on CP - search and look through them. Here is one to get you started: CSerialIO - A Useful and Simple Serial Communication Class[^]

You tagged C++, so that is the example I added here. There are other nice projects in C# if you are interested.
