SerialPort.Write()-如何停止写入? [英] SerialPort.Write() - How to stop writing?

问题描述

我正在使用SerialPort类在C#中进行开发. SerialPort.Write()是一种阻止方法. 当我想停止书写时如何退出该方法?我用线程写. 当我想停止写入但COM端口继续写入时，我中止了该线程.

I am developing in C# using the SerialPort class. SerialPort.Write() is a blocking method. How can I exit this method when I want to stop writing? I use a thread to write. I abort this thread when I want to stop writing but the COM port continues to write.

有什么想法吗?

非常感谢.

对不起，我的基本英语.

推荐答案

串行端口的流和UART都将进行缓冲.

Both the Serial Port's Stream and the UART will do buffering.

最好的方法是发送小包(行)并中断写入线程，让最后发送的包出去.如果您可以以一种民俗的方式停止写作，那么还有DiscardWriteBuffer()方法.

The best approach would be to send small packages (lines) and interrupt the writing thread, letting the last send packages go out. If you can stop the writing in a civil manner there is also the DiscardWriteBuffer() method.

如果不能选择小包装，则可以至少将WriteBufferSize设置为较小的值(但> 0).

If small packages are not an option you can a least set the WriteBufferSize to something small (but > 0).
