如何在Win7中断开蓝牙设备与C#.Net的连接

本文关键字：Net 连接 Win7 中断 断开 | 更新日期: 2023-09-27 17:58:50

我想断开蓝牙设备与运行在Win 7 x64上的c#.Net应用程序的连接。

我知道MS在.Net上提供很少的功能调节BT。

我搜索了32英尺的网络，找到了如何连接、发现、获取信息。。。但没有断开连接（我错过了什么吗？）。

然后，我在Msdn IOCTL_BTH_DISCONNECT_DEVICE上找到了。问题是我不明白该怎么称呼它。看起来我应该使用DeviceIOControl和Platform Invoke，但我担心我没有足够的.Net技能来自己构建它。

以下是我现在的位置：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
using Microsoft.Win32.SafeHandles;
using System.IO;
namespace BtDisco
{
    class Program
    {
        const int IOCTL_BTH_DISCONNECT_DEVICE = 0x41000c;
        [DllImport("Kernel32.dll", SetLastError = false, CharSet = CharSet.Auto)]
        public static extern bool DeviceIoControl(
            Microsoft.Win32.SafeHandles.SafeFileHandle hDevice,
            uint dwIoControlCode,
            [MarshalAs(UnmanagedType.AsAny)] [In] object InBuffer,
            uint nInBufferSize,
            [MarshalAs(UnmanagedType.AsAny)] [Out] object OutBuffer,
            uint nOutBufferSize,
            ref uint pBytesReturned,
            [In] ref System.Threading.NativeOverlapped Overlapped
            );
        [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)]
        static extern SafeFileHandle CreateFile(
            string lpFileName,
            [MarshalAs(UnmanagedType.U4)] FileAccess dwDesiredAccess,
            [MarshalAs(UnmanagedType.U4)] FileShare dwShareMode,
            IntPtr lpSecurityAttributes,
            [MarshalAs(UnmanagedType.U4)] FileMode dwCreationDisposition,
            [MarshalAs(UnmanagedType.U4)] FileAttributes dwFlagsAndAttributes,
            IntPtr hTemplateFile);

        static void Main(string[] args)
        {
            //http://msdn.microsoft.com/en-us/library/windows/desktop/aa363216(v=vs.85).aspx
            //hDev = Use CreateFile
            SafeFileHandle _hdev = CreateFileR(...);
            DeviceIoControl(hDev, IOCTL_BTH_DISCONNECT_DEVICE, char[] btAddr, btAddr.Length(), result, result.Length(), ref getCnt, IntPtr.Zero);
        }
    }
}

有人能帮我完成这个吗？

如何在Win7中断开蓝牙设备与C#.Net的连接

终于，我自己动手了！

我在InTheHand.Net代码中搜索了更多，终于明白了如何制作它！

这里有一些工作代码（如果你想使用它，你需要InTheHand.Net）：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Globalization;
using System.Text;
using InTheHand.Net;
using InTheHand.Net.Bluetooth;
using System.Runtime.InteropServices;
namespace BTDisco2
{
    class Program
    {
        const int IOCTL_BTH_DISCONNECT_DEVICE = 0x41000c;
        [DllImport("kernel32.dll", SetLastError = true, CharSet = CharSet.Auto)]
        internal static extern bool DeviceIoControl(
        IntPtr hDevice,
        uint dwIoControlCode,
        ref long InBuffer,
        int nInBufferSize,
        IntPtr OutBuffer,
        int nOutBufferSize,
        out int pBytesReturned,
        IntPtr lpOverlapped);
        static void Main(string[] args)
        {
            var r = BluetoothRadio.PrimaryRadio;
            var h = r.Handle;
            long btAddr = BluetoothAddress.Parse("00:1b:3d:0d:ac:31").ToInt64();
            int bytesReturned = 0;
            var success = DeviceIoControl(h,
            IOCTL_BTH_DISCONNECT_DEVICE,
            ref btAddr, 8,
            IntPtr.Zero, 0, out bytesReturned, IntPtr.Zero);
            if (!success)
            {
                int gle = Marshal.GetLastWin32Error();
                Console.WriteLine(string.Format(CultureInfo.InvariantCulture, "failure: {0} = 0x{0:X}.", gle));
            }
            else
            {
                Console.WriteLine("Success !");
            }
            while (!Console.KeyAvailable) System.Threading.Thread.Sleep(200);
        }
    }
}
