C# 用windows11 API 实现经典蓝牙的扫描、配对、通信例程

好的，以下是一个简单的C#代码示例，用于使用Windows 11 API实现经典蓝牙的扫描、配对、通信：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Windows.Devices.Bluetooth;
using Windows.Devices.Enumeration;

namespace BluetoothApp
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // 扫描蓝牙设备
            var bluetoothDevices = await DeviceInformation.FindAllAsync(BluetoothDevice.GetDeviceSelector());

            foreach (var device in bluetoothDevices)
            {
                // 显示设备名称和ID
                Console.WriteLine($"Device Name: {device.Name}, Device ID: {device.Id}");
            }

            // 选择一个蓝牙设备进行配对
            var selectedDevice = bluetoothDevices.FirstOrDefault();

            if (selectedDevice != null)
            {
                var bluetoothDevice = await BluetoothDevice.FromIdAsync(selectedDevice.Id);

                // 配对蓝牙设备
                var result = await bluetoothDevice.Pairing.TryPinPairingAsync();

                if (result.Status == BluetoothPairingResultStatus.Paired)
                {
                    Console.WriteLine("Bluetooth device paired successfully!");

                    // 连接蓝牙设备
                    var connectionResult = await bluetoothDevice.GetRfcommServicesForIdAsync(BluetoothService.SerialPort);
                    var service = connectionResult.Services.FirstOrDefault();
                    var socket = new Windows.Networking.Sockets.StreamSocket();

                    await socket.ConnectAsync(service.ConnectionHostName, service.ConnectionServiceName);

                    Console.WriteLine("Bluetooth device connected successfully!");

                    // 发送和接收数据
                    var writer = new Windows.Storage.Streams.DataWriter(socket.OutputStream);
                    writer.WriteString("Hello, Bluetooth!");

                    var reader = new Windows.Storage.Streams.DataReader(socket.InputStream);
                    await reader.LoadAsync(512);

                    var message = reader.ReadString(reader.UnconsumedBufferLength);

                    Console.WriteLine($"Received message: {message}");

                    // 断开连接
                    socket.Dispose();
                }
                else
                {
                    Console.WriteLine($"Failed to pair Bluetooth device, status: {result.Status}");
                }
            }
            else
            {
                Console.WriteLine("No Bluetooth devices found!");
            }

            Console.ReadKey();
        }
    }
}

请注意，此代码示例仅用于演示目的。实际实现可能需要更复杂的逻辑和错误处理。
