Visual Studio串行通讯

Question

IMAGEEEEEEE I'm using Visual Studio c# forms and I can't get the label to display everything the serial port reads, is there an easy way to fix this?

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace WindowsFormsApp2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            serialPort1.Open();
        }

        private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
        {
            Label1.Text = serialPort1.ReadLine();
        }
    }
}

Answer 1

private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
    var dataLength = serialPort1.BytesToRead;
    var data = new byte[dataLength];
    var nbrDataRead = serialPort1.Read(data, 0, dataLength);

    if (nbrDataRead == 0)
        return;

    Label1.Text = System.Text.Encoding.UTF8.GetString(data, 0, data.Length);
}
