USB 분산 응용 프로그램을 만들 가능성을 조사합니다
스틱을 제거 할 때 USB 스틱 삽입 및 종료시 자동 스타트가됩니다.
.NET 및 C#을 사용합니다.
제안을 찾고 C#을 사용하여 이것에 접근하는 방법을 찾으십니까?
업데이트 :이를 서비스로 구현하는 두 가지 가능한 솔루션.
-WNDPROC를 무시하십시오
또는
-ManagementEventWatcher와 함께 WMI 쿼리 사용
해결책
WMI를 사용할 수 있으며 쉽고 서비스가있는 WNDProc 솔루션보다 훨씬 잘 작동합니다.
간단한 예는 다음과 같습니다.
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();
다른 팁
이것은 나에게 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.
어디에서 이벤트를 제기합니다 어느 USB 장치가 삽입되고 다음을 사용하십시오.
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. 제가 자동 감지하려는 National Instruments DAQ 와도 작동합니다.
Vitalyb의 답변은 장치의 제거를 다루지 않습니다. 미디어가있을 때 이벤트를 트리거하기 위해 조금 변경했습니다. 삽입 그리고 제거됨 또한 삽입 된 미디어의 드라이브 문자를 얻기위한 코드도 있습니다.
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 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();
}
}
당신은 또한 사용할 수 있습니다 WMI 삽입 이벤트를 감지합니다. WM_CHANGEDEVICE 메시지를 모니터링하는 것보다 조금 더 복잡하지만 백그라운드에서 서비스로 실행중인 경우 유용 할 수있는 창 핸들이 필요하지 않습니다.
노력하다 WM_CHANDEDEVICE 손질.
다음은 WPF 앱에서 C# .NET 4.0에서 수행 한 작업입니다. 우리는 여전히 "어떤 장치 유형이 삽입/제거되었는지 알리는 방법"에 대한 답을 찾고 있지만, 이것이 시작입니다.
