等待来自C#中串口的数据

using System;
using System.IO.Ports;

class Program
{
    static void Main(string[] args)
    {
        SerialPort serialPort = new SerialPort("COM1", 9600); // 创建串口对象，指定串口号和波特率
        serialPort.DataReceived += SerialPort_DataReceived; // 注册数据接收事件
        serialPort.Open(); // 打开串口

        Console.WriteLine("等待串口数据...");

        Console.ReadKey();
        serialPort.Close(); // 关闭串口
    }

    private static void SerialPort_DataReceived(object sender, SerialDataReceivedEventArgs e)
    {
        SerialPort serialPort = (SerialPort)sender;
        string data = serialPort.ReadExisting(); // 读取接收到的数据
        Console.WriteLine("接收到的数据：" + data);
    }
}
