我们可以根据C＃中串口的时间发送文件吗？ [英] Can we send files according to time over serial port in C#?

问题描述

我创建了一个简单的GUI，通过串口发送和接收文件，我成功发送和接收文件，但我需要的是我们可以在每1秒或2秒或任何时间间隔后发送相同的文件。







任何人都可以解释如何添加时间戳



我尝试过：

I created a simple GUI which send and receive file over serial port, i successfully sent and receive the files , but what i need is can we send the same file after every 1 sec or 2 sec or any time interval.



can any one explain how to add time stamp

What I have tried:

private void butSendFile_Click(object sender, EventArgs e)
       {
           if (serialPort1.IsOpen == false)
           {
               this.serialPort1.Open();
           }
           serialPort1.Write(System.IO.File.ReadAllText(this.txtfile.Text));
       }

       private void butSetFile_Click(object sender, EventArgs e)
       {
           this.openFileDialog1.ShowDialog();

           this.txtfile.Text = this.openFileDialog1.FileName;
       }

这是我用来发送文件的代码

This is the code i used to send files

推荐答案

你真的有文本文件吗？或者您的应用程序中是否有数据首先写入文本文件然后应该通过ComPort发送？



如果你想在每一行中都有一个时间戳您的文本文件只有一个选择：

- 将您的文本文件读入Stringarray

- 向此数组的每个元素添加时间戳

- 使用Comport发送所有行



如果你想做那个循环，你应该在使用定时器之后看看（例如谷歌）。

但你应该知道以下内容：如果你的周期太快，你很容易过度充电你的Comport ......

Do you really have a Textfile ? Or do you have data inside your application which first is written into a Textfile and then should be send via ComPort ?

If you want to have a Timestamp in each line of your Textfile you have only one choice :
- read your Textfile into a Stringarray
- add to each element of this Array the Timestamp
- send all the lines with the Comport

If you want to do that cyclic you should look (with Google for example) after the use of a Timer.
But you should know the following : if you cycle is too fast you could easily overcharge your Comport ...

你可以创建一个计时器并从 Timer.Elapsed Event（System.Timers） [ ^ 。请参阅上面链接中的示例代码。

You can create a timer and send from within the Timer.Elapsed Event (System.Timers)[^]. See the example code at the above link.
