问题描述

如何在 C# 中通过串口发送我的设备 ctrl+c?

How can I send my device ctrl+c through serial port in C#?

推荐答案

串口不传输密钥.它们传输字节，通常是字符的 ASCII 表示.

Serial ports don't transmit keys. They transmit bytes, which are normally the ASCII representations of characters.

Keys.ControlKey & Keys.C"与感知 PC 上发生的事情有关键盘.但是串口并不传输键盘的整个状态.例如，F 键和箭头完全在 ASCII 之外系统.

"Keys.ControlKey & Keys.C" has to do with sensing what is going on on a PC keyboard. But serial ports do not transmit the whole state of the keyboard. For instance, the F keys and the arrows are entirely outside the ASCII system.

ASCII 图表会告诉你，例如，Ctrl-A 是 1，Ctrl-B 是 2，Ctrl-C 是 3，'A' 是 65，依此类推.

An ASCII chart will tell you that, for instance, Ctrl-A is 1, Ctrl-B is 2, Ctrl-C is 3, 'A' is 65, and so on.
