How to get information from device manager?
提问by Afra
How can I, in my C# applictation, read specific information about a device? I have tried WMI and it does not provide the information that I need.
如何在我的 C# 应用程序中读取有关设备的特定信息？我尝试过 WMI，但它没有提供我需要的信息。
The information that I want is stored in the Details tab of a device and the information I want there is "Parent".
我想要的信息存储在设备的“详细信息”选项卡中，我想要的信息是“父级”。
I have also looked in regedit, without any luck.
我也看过regedit，没有任何运气。

From C#, it might be easier to capture the output of devcon than integrating the APIs. If you feel comfortable with it, C++/CLI is by far the easiest way to get device information into .NET (I've done this before).
在 C# 中，捕获 devcon 的输出可能比集成 API 更容易。如果您对它感到满意，C++/CLI 是迄今为止将设备信息获取到 .NET 的最简单方法（我之前已经这样做过）。

Looks like SetupAPI can be used as an alternative on Windows Vista or newer. The above method works on Win2000+
看起来 SetupAPI 可以用作 Windows Vista 或更新版本的替代方案。以上方法适用于Win2000+
