e.g: if I run notepad.exe c:\autoexec.bat,

How can I get c:\autoexec.bat in Get-Process notepad in PowerShell?

Or how can I get c:\autoexec.bat in Process.GetProcessesByName("notepad"); in C#?

In PowerShell you can get the command line of a process via WMI:

$process = "notepad.exe"
Get-WmiObject Win32_Process -Filter "name = '$process'" | Select-Object CommandLine

Note that you need admin privileges to be able to access that information about processes running in the context of another user. As a normal user it's only visible to you for processes running in your own context.
