您可以使用该功能的 SHChangeNotifyRegister 以 WM_FILECHANGEINFO 的消息。

You can use the function SHChangeNotifyRegister to WM_FILECHANGEINFO message.

您订阅，您将收到与IDS事件，如 SHCNE_DRIVEREMOVED 或 SHCNE_MEDIAREMOVED 之后，这样你就可以触发当删除了一些动作的存储卡。

After you subscribe, you will be receiving events with ids such as SHCNE_DRIVEREMOVED or SHCNE_MEDIAREMOVED, so you can trigger some actions when storage card is removed.

要使用本机的功能，从紧凑的框架，使用的P / Invoke。

To use native functions from the compact framework, use P/Invoke.
