How to monitor the IO activity of the process using C #?

advertisements

Using FileSystemWatcher we can monitor the IO activity of a particular file system, but is there anyway to know that which one of the running processes is causing that IO?

More specifically, suppose a running process viz. abc.exe is creating a file text.txt on drive D. We can monitor that a file named text.txt has been created in drive D using FileSystemWatcher, but can we determine programmatically that a process named abc.exe is creating that particular file in drive D?


handle.exe from SysInternals is a command line tool that allow programmatic access to which program has a particular file or directory open.

C:\>handle.exe c:\Windows\system32\stdole2.tlb

Produces this output:

Handle v3.42

devenv.exe         pid: 5240    184: C:\Windows\System32\stdole2.tlb
Ssms.exe           pid: 5000    1F4: C:\Windows\System32\stdole2.tlb

Which can be parsed programmatically.
