在VS中从arduino接收字符串，如何将其存储在csv或xls文件中？

Question

So I'm reading strings from my arduino via serialPort, using C#. The strings show in a text box when I do the supposed action. What I need to do now is to put them in an array and store them at a csv or xls file.

    private void btRecOn_Click(object sender, EventArgs e)
    {
        if (serialPort1.IsOpen == true)             // COMport is open                
            Text = recon;             // string recon = "recording on"
            serialPort1.Write(Text);  // sends text "recording on" to arduino
    }

    private void SerialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        RxString = serialPort1.ReadExisting();            // reads data from serial port
        this.Invoke(new EventHandler(trataDadoRecebido)); // calls another thread to write data in text
    }   

    private void trataDadoRecebido(object sender, EventArgs e)
    {
        textBoxReceber.AppendText(RxString);         
    }

My objective is to press the "save" button and those strings be saved in different lines of a csv or xls file. I already tried through interop, but it gets messy! What is the best way in your opinion?

Could you give me some help or tips?

Thanks in advance.

Answer 1

My suggestion would be to change the textbox into a listbox. In that way you got separate string items which you can write to a file.

Another advantage of using a listbox will be that you can make a selection of items that you want to write into a file.
