推荐答案

为什么注册表项会存储网络适配器的状态?您的身份是什么意思?如果您使用的是WMI，那么您将使用最佳的过程.也许您需要轮询它并存储值，以便可以快速获取它并假定它没有更改?

Why would a registry key store the status of a network adapter ? What do you mean by status ? If you''re using WMI, you''re using the best possible process. Perhaps you need to poll it and store the value so you can get it quickly and assume it''s not changed?
