C# WMI实现USB设备的上下线监听

主要引用

using System.Management;

需要在代码集里手动添加，无法自动添加

代码实现

添加监听

        /// 

        /// 添加USB设备监视
        /// 
        /// 
        public bool AddUSBEventWatcher()
        {
            try
            {
                var scope = new ManagementScope("root\\CIMV2");
                var insert = new WqlEventQuery("__InstanceCreationEvent", TimeSpan.FromSeconds(1), "TargetInstance isa 'Win32_USBControllerDevice'");
                var remove = new WqlEventQuery("__InstanceDeletionEvent", TimeSpan.FromSeconds(1), "TargetInstance isa 'Win32_USBControllerDevice'");

                _insertWatcher = new ManagementEventWatcher(scope, insert);
                _removeWatcher = new ManagementEventWatcher(scope, remove);

                ///WMI服务USB加载响应事件
                _insertWatcher.EventArrived += OnUSBInserted;
                ///WMI服务USB移除响应事件
                _removeWatcher.EventArrived += OnUSBRemoved;

                ///开启监听
                _insertWatcher.Start();
                _removeWatcher.Start();

                return true;
            }
            catch (Exception)
            {
                Dispose();
                return false;
            }
        }

上线消息处理

        /// 

        /// Usb设备上线处理方法
        /// 
        /// 
        /// 
        private void OnUSBInserted(object sender, EventArrivedEventArgs e)
        {
            string dependent = UsbDeviceInfo.WhoUsbControllerDevice(e).Dependent;
            string text = dependent.Replace("\\\\", "\\");

            ///Usb存储类设备标志
            if (text.StartsWith("USBSTOR\\"))
            {
                UsbStorageInserted?.Invoke(this, new UsbStorageCreatEventArgs(text, dependent));
            }
            else if (text.StartsWith("HID\\"))
            {
                PnPEntityInfo[] pnPEntityInfos = UsbDeviceInfo.WhoPnPEntity(text);

                for (int i = 0; !(pnPEntityInfos == null) && i < pnPEntityInfos.Length; i++)
                {
                    ///通过guid去判定当前上线设备是什么类别的设备
                    if (pnPEntityInfos[i].ClassGuid == Mouse)
                    {
                        HIDMouseInserted?.Invoke(this, pnPEntityInfos[i]);
                    }
                    else if (pnPEntityInfos[i].ClassGuid == Keyboard)
                    {
                        HIDKeyboardInserted?.Invoke(this, pnPEntityInfos[i]);
                    }
                }
            }
        }

下线消息处理

        /// 

        /// Usb设备下线处理方法
        /// 
        /// 
        /// 
        private void OnUSBRemoved(object sender, EventArrivedEventArgs e)
        {
            string dependent = UsbDeviceInfo.WhoUsbControllerDevice(e).Dependent;
            string text = dependent.Replace("\\\\", "\\");

            ///Usb存储类设备标志
            if (text.StartsWith("USBSTOR\\"))
            {
                UsbStorageRemoved?.Invoke(this, new UsbStorageDeleteEventArgs(text));
            }
        }

方法调用

        static void Main(string[] args)
        {
            UsbMonitor();

            Console.ReadLine();

            Dispose();
        }
        /// 

        /// Usb设备上下线监控方法
        /// 
        static void UsbMonitor()
        {
            _usbDeviceWatcher = UsbDeviceWatcher.Instance;

            _usbDeviceWatcher.UsbStorageInserted += UsbStorageInsertedHandler;

            _usbDeviceWatcher.UsbStorageRemoved += UsbStorageRemovedHandler;
        }

最重要的来了(感觉不错记得⭐一下）
