C#编程连接蓝牙设备,收发.docx

现在很多电脑提供了蓝牙支持，很多笔记本网卡也集成了蓝牙功能，也可以采用USB蓝牙方便的连接手机等蓝牙设备进行通信。操作蓝牙要使用类库InTheHand.Net.Personal首先在项目中引用该类库；C#代码1. staticvoidMain(stringargs)2. 3. BluetoothRadiobluetoothRadio=BluetoothRadio.PrimaryRadio;4. if(bluetoothRadio=null)5. 6. Console.WriteLine(没有找到本机蓝牙设备!);7. 8. else9. 10. Console.WriteLine(ClassOfDevice:+bluetoothRadio.ClassOfDevice);11. Console.WriteLine(HardwareStatus:+bluetoothRadio.HardwareStatus);12. Console.WriteLine(HciRevision:+bluetoothRadio.HciRevision);13. Console.WriteLine(HciVersion:+bluetoothRadio.HciVersion);14. Console.WriteLine(LmpSubversion:+bluetoothRadio.LmpSubversion);15. Console.WriteLine(LmpVersion:+bluetoothRadio.LmpVersion);16. Console.WriteLine(LocalAddress:+bluetoothRadio.LocalAddress);17. Console.WriteLine(Manufacturer:+bluetoothRadio.Manufacturer);18. Console.WriteLine(Mode:+bluetoothRadio.Mode);19. Console.WriteLine(Name:+bluetoothRadio.Name);20. Console.WriteLine(Remote:+bluetoothRadio.Remote);21. Console.WriteLine(SoftwareManufacturer:+bluetoothRadio.SoftwareManufacturer);22. Console.WriteLine(StackFactory:+bluetoothRadio.StackFactory);23. 24. Console.ReadKey();25. 如果PC插入了蓝牙适配器，便会显示蓝牙相关信息：然后我们就要利用蓝牙收发文件了：前提是蓝牙设备(如手机)已经和PC配对了C#代码1. publicpartialclassForm1:Form2. 3. BluetoothRadioradio=null;/蓝牙适配器4. stringsendFileName=null;/发送文件名5. BluetoothAddresssendAddress=null;/发送目的地址6. ObexListenerlistener=null;/监听器7. stringrecDir=null;/接受文件存放目录8. ThreadlistenThread,sendThread;/发送/接收线程9. 10. publicForm1()11. 12. InitializeComponent();13. radio=BluetoothRadio.PrimaryRadio;/获取当前PC的蓝牙适配器14.
