亲爱的所有人；

我有一个使用c#的winForm，这种形式的文本框显示一些数据，我只想在连接到我的台式机的LED屏幕上显示此数据.
该怎么办?

[根据OP后来写的内容进行编辑]
有一个通过串行端口连接到我的PC的移动LED屏幕:在我的Windows窗体中，文本框中的某些结果必须仅在该LED屏幕上显示.

推荐答案

这取决于LED屏幕.
您需要调查其文档.很可能会有一些命令可以发送到屏幕.并且必须能够告诉屏幕应显示什么文本.找出屏幕在其串行接口上​​的期望.

尝试通过Windows''超级终端或某些类似程序进行连接.这样，您就可以在命令和文本长度等方面玩一些.

当您知道要发送的内容时，串行端口类 [ ^ ]是您需要以编程方式执行的操作.

It depends on the LED screen.
You need to investigate its documentation. Most likely there will be some commands that you can send to the screen. And there has to be a possibility to tell the screen what text it should display. Find out what the screen expects at its serial interface.

Try to connect via Windows'' HyperTerminal or some similar program. This way you can play around a little with commands and text lengths and so on.

When you know what you want to send, the serial port class[^] is what you need to do it programatically.

但这不是我的问题，换句话说:
有一个通过串行端口连接到我的PC的移动LED屏幕:在我的Windows窗体中，文本框中的某些结果必须仅在该LED屏幕上显示.
所以我的问题是如何在led屏幕上显示文本框的值?
