VB.net Get username of locked file in network location

Question

Hello I am attempting to find a way in .Net that gives the name of a user who has a file open in a network location. I prefer to use a .Net library and avoid wrapping openfiles.exe.

Any help is apprecited!

Answer 1

openfiles.exe uses NtQuerySystemInformation (mainly with SystemExtendedHandleInformation),
so it is complicated and it is easier to parse the output of openfiles.exe...

Answer 2

We open file with FILE_READ_ATTRIBUTES and call NtQueryInformationFile with FileProcessIdsUsingFileInformation. on return we got FILE_PROCESS_IDS_USING_FILE_INFORMATION structure where list of ProcessId which hold this file. Here is a sample.
