您将需要一个窗口，无法解决。这是一个示例实现。为DeviceChangeNotifier.DeviceNotify事件实现事件处理程序以获取通知。在程序开始时调用DeviceChangeNotifier.Start（）方法。在程序末尾调用DeviceChangeNotifier.Stop（）。请注意，DeviceNotify事件是在后台线程上引发的，请确保根据需要锁定以保持代码线程安全。

using System;
using System.Windows.Forms;
using System.Threading;

class DeviceChangeNotifier : Form {
  public delegate void DeviceNotifyDelegate(Message msg);
  public static event DeviceNotifyDelegate DeviceNotify;
  private static DeviceChangeNotifier mInstance;

  public static void Start() {
    Thread t = new Thread(runForm);
    t.SetApartmentState(ApartmentState.STA);
    t.IsBackground = true;
    t.Start();
  }
  public static void Stop() {
    if (mInstance == null) throw new InvalidOperationException("Notifier not started");
    DeviceNotify = null;
    mInstance.Invoke(new MethodInvoker(mInstance.endForm));
  }
  private static void runForm() {
    Application.Run(new DeviceChangeNotifier());
  }

  private void endForm() {
    this.Close();
  }
  protected override void SetVisibleCore(bool value) {
    // Prevent window getting visible
    if (mInstance == null) CreateHandle();
    mInstance = this;
    value = false;
    base.SetVisibleCore(value);
  }
  protected override void WndProc(ref Message m) {
    // Trap WM_DEVICECHANGE
    if (m.Msg == 0x219) {
      DeviceNotifyDelegate handler = DeviceNotify;
      if (handler != null) handler(m);
    }
    base.WndProc(ref m);
  }
}
