Does anybody know the way to get devices attached to PCI Express slots by using WMI?
I've been using Win32_PnPEntity class, but I can't make a distinguish between PCI and PCI Express devices.

AFAIK 没有 WMI 类或属性可以直接以可靠的方式检测 PCI Express 设备，但作为解决方法，您可以检查WMI 类属性中的PCI Express字符串。DescriptionWin32_PnPEntity
SELECT * FROM Win32_PnPEntity Where Description LIKE "%PCI Express%"
