C#发送文件到蓝牙设备

测试环境：

visual studio 2022

win11笔记本电脑，具有蓝牙功能

.net6控制台

测试步骤如下：

1 新增名为BluetoothDemo控制台项目

2 通过nuget安装InTheHand.Net.Bluetooth，版本选择4.2.1和安装InTheHand.Net.Obex，版本选择4.1.0，如下图：

3 在程序的bin/Debug目录下新增一个名为test.txt的文本文件，内容随便填点东西

4 在主程序中编辑代码如下：

using InTheHand.Net.Obex;
using InTheHand.Net.Bluetooth;
using InTheHand.Net.Sockets;
using System.Text;
using InTheHand.Net;using (var client = new BluetoothClient())
{// 搜索附近的蓝牙设备var devices = client.DiscoverDevices();foreach (var device in devices){Console.WriteLine($"Name: {device.DeviceName}, Address: {device.DeviceAddress}");}
}//从前面的扫描蓝牙设备中获取到的设备地址
string deviceAddress = "3839CDC9171A";
BluetoothAddress address = BluetoothAddress.Parse(deviceAddress);
Guid serviceClass = BluetoothService.ObexObjectPush;
//在程序的bin/Debug目录下新增一个test.txt文件
string filePath = "test.txt"; Uri uri = new Uri($"obex://{deviceAddress}/{System.IO.Path.GetFileName(filePath)}");ObexWebRequest request = new ObexWebRequest(uri);
request.ReadFile(filePath);using (ObexWebResponse response = (ObexWebResponse)request.GetResponse())
{if (response.StatusCode == (ObexStatusCode.OK|ObexStatusCode.Final)){Console.WriteLine("文件发送成功");}else{Console.WriteLine("文件发送失败: " + response.StatusCode);}
}Console.WriteLine("Hello, World!");

上述代码中的地址deviceAddress根据实际情况填写

程序运行结果如下：
