c#遍历匹配串口（向每个串口发数据，根据返回数据确定是否为所需串口） C#

最近在公司有一个项目需要遍历串口，查找设备采用的串口，我的想法是遍历机器上所有串口，对每个串口发送数据，根据串口返回的数据判断该串口是否是目标设备所使用的串口（已有设备串口指令手册），本次采用c#实现。
代码如下：

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; using System.IO.Ports; using System.Threading; namespace 切割1 { public partial class Form1 : Form { public SerialPort ComDevice = new SerialPort(); string[] two = SerialPort.GetPortNames(); string data3 =""; public Form1() { InitializeComponent(); ComDevice.DataReceived += new SerialDataReceivedEventHandler(recivedata); //绑定事件 Getname(); } public void initport(int i)//初始化串口数据 {if (ComDevice.IsOpen) { ComDevice.Close(); ComDevice.PortName = two[i]; ComDevice.BaudRate = 115200; ComDevice.Parity = Parity.None; ComDevice.DataBits = 8; ComDevice.StopBits = StopBits.One; } else { ComDevice.PortName = two[i]; ComDevice.BaudRate = 115200; ComDevice.Parity = Parity.None; ComDevice.DataBits = 8; ComDevice.StopBits = StopBits.One; } ComDevice.Open(); }private byte[] strToHexByte(string hexString)//字符串转换为byte[] { hexString = hexString.Replace(" ", ""); if ((hexString.Length % 2) != 0) hexString += " "; byte[] returnBytes = new byte[hexString.Length / 2]; for (int i = 0; i < returnBytes.Length; i++) returnBytes[i] = Convert.ToByte(hexString.Substring(i * 2, 2).Replace(" ", ""), 16); return returnBytes; }public bool senddata()//发送数据 { string data1 = "55 05 00 00 00 FF 01 01 00 00 00 00 5B 0D"; byte[] data2 = null; data2 = strToHexByte(data1); if (ComDevice.IsOpen) { try { ComDevice.Write(data2, 0, data2.Length); //发送数据 return true; } catch (Exception ex) { MessageBox.Show(ex.Message, "错误", MessageBoxButtons.OK, MessageBoxIcon.Error); } } else { MessageBox.Show("串口未打开", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error); } return false; }public void recivedata(object sender, SerialDataReceivedEventArgs e)//接收读取数据 {byte[] ReDatas = new byte[ComDevice.BytesToRead]; ComDevice.Read(ReDatas, 0, ReDatas.Length); //读取数据 adddata(ReDatas); }public void adddata(byte[] data) { StringBuilder sb = new StringBuilder(); for (int i = 0; i < data.Length; i++) { sb.AppendFormat("{0:x2}" + " ", data[i]); } data3 = sb.ToString().ToUpper(); //MessageBox.Show(data3); }public void Getname()//根据自己所设条件遍历匹配串口并打开该串口 {//string data2 = "55 0A 00 00 00 FE 01 01 00 00 00 00 1E 10 10 00 00 9D 0D "; try { for (int i = 0; i < two.Length; i++) { initport(i); senddata(); System.Threading.Thread.Sleep(50); if (data3.Contains("9D")) { //ComDevice.Close(); break; } ComDevice.Close(); }} catch (Exception ex) { MessageBox.Show(ex.ToString()); } //MessageBox.Show(data3); //ComDevice.Close(); //return ComDevice.PortName; }private void button1_Click(object sender, EventArgs e)//串口一个按钮事件 { string data1 = "55 05 00 00 00 FF 02 09 03 05 00 00 6C 0D"; byte[] data = https://www.it610.com/article/strToHexByte(data1); try { ComDevice.Write(data, 0, data.Length); //发送数据} catch (Exception ex) {} }} }

【c#遍历匹配串口（向每个串口发数据，根据返回数据确定是否为所需串口）】经测试可以达到预期效果，如果有好的方法，请留言，本人小菜一枚
