本文介绍了（C＃）如何使hexdump与串口一起工作？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我在.hex中通过UART获取数据到TextBox，我收到stardart格式：
[]
但是我需要让它以HexDump格式显示，我在COdeProject中找到了一个例子

并试过我自己，什么都没发生，好像我用错了，请帮忙，我现在真的很挣扎

Hi,
I'm gettin data in .hex through UART to TextBox, i received it in stardart format:
What im getting now[^]
But i need to make it shown in HexDump format, i found an example in COdeProject
Quick and Dirty HexDump of a Byte Array[^]
And tried it by my own, nothing happend, seems like im using it wrong, please help, im really in struggle now
What I have tried:
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;

public partial class Form1 : Form

InitializeComponent();
}
private void button1_Click(object sender, EventArgs e) // Here i send a byte to MK
{
// serialPort1.RtsEnable = true; serialPort1.DtrEnable = true;
// var content = new List<byte>();
// content.AddRange(Encoding.ASCII.GetBytes("1"));
// content.Add(3); // ASCII ETX
//byte[] buffer = content.ToArray();
// serialPort1.Write(buffer, 0, buffer.Length);
//byte[] MyMessage = System.Text.Encoding.UTF8.GetBytes("2");
//serialPort1.Write(MyMessage, 0, MyMessage.Length);
serialPort1.Write("\u0005");
serialPort1.Write(Convert.ToString(0x05));
}
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e) // choosing a right com port
{
serialPort1.PortName = textBox1.Text;
serialPort1.BaudRate = Convert.ToInt32(textBox2.Text);
}
string rs;
byte re;
private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e) // Da
{
try
{
//rs = serialPort1.ReadByte();
//re = Convert.ToByte(serialPort1.ReadByte());
