更新:将此作为服务实现的两种可能的解决方案.
- 覆盖 WndProc
或
- 在 ManagementEventWatcher 中使用 WMI 查询

Update: Two possible solutions implementing this as a service.
- override WndProc
or
- using WMI query with ManagementEventWatcher

推荐答案

您可以使用 WMI，它很简单，而且比 WndProc 解决方案和服务要好得多.

You can use WMI, it is easy and it works a lot better than WndProc solution with services.

这是一个简单的例子:

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();
