c# - Find process id by window's handle

i have a problem with getting a specific PID of a process, the problem with this process is that it's a hidden process, it's not showing on task manager / powershell, completely hidden.

what i have do far is the main window handle of this process, the question is, how can i get the pid of it.

what i'm trying to do is to read the memory of this process and edit it, but can't do so without the PID i guess (since i need to get it's base address in memory).

So, if anyone has any workaround or something for me, it will be great.

P.S: this process does not show in Process.GetProcesses().

ty!

You can use the following Windows API:

[DllImport("user32.dll", SetLastError=true)]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint processId);

You pass in the HWND and use the out parameter to return the PID.

You can read more on this function here on MSDN.
