Determining the parent process id from C#

Question

I would like to determine the process id of the parent process for an arbitrary process in Windows.

I need this method to work on both x64 and x32.

Any ideas / sample code to make this happen. System.Diagnositics.Process does not include this info.

I am a bit worried about using the toolhelp apis cause they are 32 bit specific.

Related info:

C++ implementation
Some thing I googled (the interop there is not x64 freindly)

The Performance counter solution in the FAQ: (PerformanceCounter("Process", "Creating Process ID", procName);) scares me, cause it does not allow you to enter a process id, instead you specify a process by name so it all can go pear shape when you have multiple children.

[This question](http://stackoverflow.com/questions/394816/how-to-get-parent-process-in-net-in-managed-way) has a code example in it. — Roman Starkov, Nov 28 '09 at 18:12

WIN32_Process has processid and parent processid. Getting the WMI data on 64-bit is a bit more difficult, but still possible by changing the provider flags.

yeah System.Management is a much easier path to take – Sam Saffron Apr 22 '09 at 06:06

Use NAPI (Win32 FAQ)

That's a very poor answer. – svick Feb 26 '13 at 15:28
