How to get information from device manager?

How can I, in my C# applictation, read specific information about a device? I have tried开发者_JAVA百科 WMI and it does not provide the information that I need.

The information that I want is stored in the Details tab of a device and the information I want there is "Parent".

I have also looked in regedit, without any luck.

Microsoft provides a sample: http://support.microsoft.com/kb/311272

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).

These APIs should get you going: http://msdn.microsoft.com/en-us/library/ff550630(VS.85).aspx#retrieving_the_parent_of_a_device_inst

Looks like SetupAPI can be used as an alternative on Windows Vista or newer. The above method works on Win2000+
