C# 从接收到的串行数据返回值到另一个函数

我正在通过Arduino从距离传感器获取串行数据到Visual Studio，我有另一台由另一个控制器控制的机器

从接收到的串行数据返回值到另一个函数

我的问题是：如何从函数返回值

public void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)

到函数内部的while循环

private void btnMove_Click(object sender, EventArgs e)

我的代码如下：

using System;
using System.Windows.Forms;
using PokeysLibSR;
using System.Drawing;
using System.Diagnostics;
using System.Threading;
using System.IO.Ports;
using System.Text.RegularExpressions;

namespace Melexis
{

public partial class Form1 : Form
{
    PokeysLib pokeys;

    public Form1()
    {  
       InitializeComponent();
       serialPort1.BaudRate = 9600;
       serialPort1.PortName = "COM3";
    }
}

private void button1_Click(object sender, EventArgs e)
{
    serialPort1.Open();
}

public void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
        try
        {
            string line = serialPort1.ReadLine();
            string yourPortStringFormatted = Regex.Replace(line, @"\t|\n|\r", "");
            string yourPortStringFormatted1 = yourPortStringFormatted.Trim();
            double portNum = Double.Parse(yourPortStringFormatted1);
            string line1 = Convert.ToString(portNum / 100);
            this.BeginInvoke(new LineReceivedEvent(LineReceived), line1);

        }
        catch { }
        finally
        {
            GC.Collect();
        }
}

private delegate void LineReceivedEvent(string line1);

private void LineReceived(string line1)
{
    textBox1.Text = line1;
}

private void btnMove_Click(object sender, EventArgs e)
{
        double[] coords = new double[4] { 0, 0, 0, 0 };
        byte axisMask = 0;

        if (double.TryParse(tbX.Text, out coords[0])) axisMask = (byte)(axisMask + 1);
        if (double.TryParse(tbY.Text, out coords[1])) axisMask = (byte)(axisMask + 2);
        if (double.TryParse(tbZ.Text, out coords[2])) axisMask = (byte)(axisMask + 4);
        while (true)
        {
          pokeys.StartMove(false, rbAbsolut.Checked, 1, coords);
            Thread.Sleep(5000);
            coords[0] = -coords[0];
           pokeys.StartMove(false, rbAbsolut.Checked, 4, coords);
            coords[2] = coords[2] + 10;
            Thread.Sleep(5000);
        }
    }
}

目前，您有一个永无止境的while循环，我不推荐

serialPort1.ReadLine（）。我会使用
serialPort1.ReadExisting（）但请注意，您必须跟踪字符串。您可能需要构建字符串，直到看到换行符，然后调用传递该字符串的函数。看见
