How to get command line args of a process by id?

Question

I have an ID of a running process (launched not by me). How can I get its command line arguments?

Answer 1

you can use wmi to get this kind of info

var q = string.Format("select CommandLine from Win32_Process where ProcessId='{0}'", processId);
ManagementObjectSearcher searcher = new ManagementObjectSearcher(q);
ManagementObjectCollection result = searcher.Get();
foreach (ManagementObject obj in result)
    Console.WriteLine("[{0}]", obj["CommandLine"]);
