How to get open / used files of a working process

Question

I am trying to figure out a way to get used process files to show which files are currently being opened / used by this process.

I found a list of used files .
Is there a link to get this in C #?

The NtQuerySystemInformation function seems like a logical starting point, but you will need to access it through P / Invoke .

googling , , ( , PInvoke.net).
