Windows 서비스 및 C #을 사용하여 USB 드라이브 삽입 및 제거 감지

Windows 서비스 및 C #을 사용하여 USB 드라이브 삽입 및 제거 감지

---

USB 스틱 삽입시 자동 시작되고 스틱 제거시 종료 되는 USB 분산 응용 프로그램 을 만들 가능성 검토

.Net 및 C #을 사용합니다.
C #을 사용하여 이에 접근하는 방법에 대한 제안을 찾고 계십니까?

---

업데이트 :이를 서비스로 구현하는 두 가지 가능한 솔루션입니다.
-WndProc 재정의
또는 -ManagementEventWatcher
와 함께 WMI 쿼리 사용

---

WMI를 사용할 수 있으며 사용하기 쉽고 서비스가있는 WndProc 솔루션보다 훨씬 잘 작동합니다.

다음은 간단한 예입니다.

using System.Management;

ManagementEventWatcher watcher = new ManagementEventWatcher();
WqlEventQuery query = new WqlEventQuery("SELECT * FROM Win32_VolumeChangeEvent WHERE EventType = 2");
watcher.EventArrived += new EventArrivedEventHandler(watcher_EventArrived);
watcher.Query = query;
watcher.Start();
watcher.WaitForNextEvent();

---

이것은 저에게 잘 작동하며 장치에 대한 자세한 정보를 찾을 수 있습니다.

using System.Management;

private void DeviceInsertedEvent(object sender, EventArrivedEventArgs e)
{
    ManagementBaseObject instance = (ManagementBaseObject)e.NewEvent["TargetInstance"];
    foreach (var property in instance.Properties)
    {
        Console.WriteLine(property.Name + " = " + property.Value);
    }
}

private void DeviceRemovedEvent(object sender, EventArrivedEventArgs e)
{
    ManagementBaseObject instance = (ManagementBaseObject)e.NewEvent["TargetInstance"];
    foreach (var property in instance.Properties)
    {
        Console.WriteLine(property.Name + " = " + property.Value);
    }
}            

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    WqlEventQuery insertQuery = new WqlEventQuery("SELECT * FROM __InstanceCreationEvent WITHIN 2 WHERE TargetInstance ISA 'Win32_USBHub'");

    ManagementEventWatcher insertWatcher = new ManagementEventWatcher(insertQuery);
    insertWatcher.EventArrived += new EventArrivedEventHandler(DeviceInsertedEvent);
    insertWatcher.Start();

    WqlEventQuery removeQuery = new WqlEventQuery("SELECT * FROM __InstanceDeletionEvent WITHIN 2 WHERE TargetInstance ISA 'Win32_USBHub'");
    ManagementEventWatcher removeWatcher = new ManagementEventWatcher(removeQuery);
    removeWatcher.EventArrived += new EventArrivedEventHandler(DeviceRemovedEvent);
    removeWatcher.Start();

    // Do something while waiting for events
    System.Threading.Thread.Sleep(20000000);
}

VitalyB의 게시물에 추가.

이벤트 발생 시키려면 모든 USB 장치가 삽입됩니다, 다음을 사용 :

var watcher = new ManagementEventWatcher();
var query = new WqlEventQuery("SELECT * FROM Win32_DeviceChangeEvent WHERE EventType = 2");
watcher.EventArrived += new EventArrivedEventHandler(watcher_EventArrived);
watcher.Query = query;
watcher.Start();

USB 장치가 연결될 때마다 이벤트가 발생합니다. 자동 감지하려는 National Instruments DAQ에서도 작동합니다.

VitalyB의 답변은 장치 제거를 다루지 않습니다. 미디어를 삽입 하고 제거 할 때 이벤트를 트리거 하고 삽입 된 미디어의 드라이브 문자를 가져 오는 코드도 약간 변경했습니다 .

using System;
using System.Management;

namespace MonitorDrives
{
    class Program
    {
        public enum EventType
        {
            Inserted = 2,
            Removed = 3
        }

        static void Main(string[] args)
        {
            ManagementEventWatcher watcher = new ManagementEventWatcher();
            WqlEventQuery query = new WqlEventQuery("SELECT * FROM Win32_VolumeChangeEvent WHERE EventType = 2 or EventType = 3");

            watcher.EventArrived += (s, e) =>
            {
                string driveName = e.NewEvent.Properties["DriveName"].Value.ToString();
                EventType eventType = (EventType)(Convert.ToInt16(e.NewEvent.Properties["EventType"].Value));

                string eventName = Enum.GetName(typeof(EventType), eventType);

                Console.WriteLine("{0}: {1} {2}", DateTime.Now, driveName, eventName);
            };

            watcher.Query = query;
            watcher.Start();

            Console.ReadKey();
        }
    }
}

위의 모든 답변에 대한 약간의 편집 :

using System.Management;

public partial class MainForm : Form
{
    public MainForm()
    {
        InitializeComponent();

        bgwDriveDetector.DoWork += bgwDriveDetector_DoWork;
        bgwDriveDetector.RunWorkerAsync();
    }

    private void DeviceInsertedEvent(object sender, EventArrivedEventArgs e)
    {
        string driveName = e.NewEvent.Properties["DriveName"].Value.ToString();
        MessageBox.Show(driveName + " inserted");
    }

    private void DeviceRemovedEvent(object sender, EventArrivedEventArgs e)
    {
        string driveName = e.NewEvent.Properties["DriveName"].Value.ToString();
        MessageBox.Show(driveName + " removed");
    }

    void bgwDriveDetector_DoWork(object sender, DoWorkEventArgs e)
    {
        var insertQuery = new WqlEventQuery("SELECT * FROM Win32_DeviceChangeEvent WHERE EventType = 2");
        var insertWatcher = new ManagementEventWatcher(insertQuery);
        insertWatcher.EventArrived += DeviceInsertedEvent;
        insertWatcher.Start();

        var removeQuery = new WqlEventQuery("SELECT * FROM Win32_DeviceChangeEvent WHERE EventType = 3");
        var removeWatcher = new ManagementEventWatcher(removeQuery);
        removeWatcher.EventArrived += DeviceRemovedEvent;
        removeWatcher.Start();
    }
}

WMI 를 사용 하여 삽입 이벤트를 감지 할 수도 있습니다 . WM_CHANGEDEVICE 메시지를 모니터링하는 것보다 조금 더 복잡하지만 백그라운드에서 서비스로 실행하는 경우 유용 할 수있는 창 핸들이 필요하지 않습니다.

---

WM_CHANGEDEVICE 처리를 시도하십시오 .

다음은 WPF 앱에서 C # .Net 4.0으로 수행 한 작업입니다. 우리는 여전히 "어느 장치 유형이 삽입 / 제거되었는지 확인하는 방법"에 대한 답변을 찾고 있지만 이것은 시작입니다.

    using System.Windows.Interop;
...
public partial class MainWindow : Window
 {
    ...
    public MainWindow()
    {
    ...
    }

    //============================================================
    // WINDOWS MESSAGE HANDLERS
    // 

    private const int WM_DEVICECHANGE = 0x0219;  // int = 537
    private const int DEVICE_NOTIFY_ALL_INTERFACE_CLASSES = 0x00000004; 

    /// <summary>
    ///
    /// </summary>
    /// <param name="e"></param>
    protected override void OnSourceInitialized(EventArgs e)
    {
        base.OnSourceInitialized(e);
        HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
        source.AddHook(WndProc);
    }

    private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
    {
        if (msg == WM_DEVICECHANGE)
        {
            ReadDongleHeader();
        }
        return IntPtr.Zero;
    }
