Get Device information according to GUID

[Schneider@discussions.microsoft.com Shiri Schneider]

Hello,

I am interested in getting the device information in c#.
I am writing the user mode of a device driver in c# and I have the GUID of
the device.
I would like to get the symbolic name (friendly name) of the device (all the
devices) that belongs to the specific GUID (in c#, not in native).

Thanks,

Shiri.

Your description is a bit confused, but there are certainly samples on the
web showing how to call the SetupDi APIs from managed code.

Why do you shun native code so?

Hi Tim,

Thanks for your response.
I tried using SetupDi functions in my code and i couldn't get the friendly
name of the device properly.
That's why i was intersted in getting the friendly name in other way without
using SetupDi.
Do you know if there us an API in the WMI that expose this options? - if not
do you have an example of using SetupDi in c# to get the friendly name
according to GUID.

Thanks a lot.
Shiri.

SetupDi is the right way. There are a lot of parameters, and a lot of ways
to get them wrong.

I believe it is exposed through WMI, but I'm not enough of a WMI guy to
know it.
