My C# application is going to be executed by another exe file. When my application is loaded, I need to get the calling exe file path.

I can get my own application path by following code;

  Application.ExecutablePath;

But how to get the caller exe path? Any help would be highly appreciated.

The executable path of the process who called `CreateProcess` that started your application ? – TheGeneral Aug 27 '20 at 07:35

How is it "called"? Is it used like a lib or via `Process.Start()` ? – Fildor Aug 27 '20 at 07:36
Michael Randall The caller application is not owned by me. So I'am not able to pass it's path to my application. Any idea? – Ruwan Liyanage Aug 27 '20 at 07:37

Fildor, I think it is called using Process.Start() – Ruwan Liyanage Aug 27 '20 at 07:38

Get the `parent process` as shown [here](https://stackoverflow.com/questions/394816/how-to-get-parent-process-in-net-in-managed-way) and retrieve its path. – Axel Kemper Aug 27 '20 at 07:40

^^ Mind to look into [Simon's answer](https://stackoverflow.com/a/3346055/982149) over the accepted one. – Fildor Aug 27 '20 at 07:43
The code by Simon Mourier given me the IDE path on debugging, but compiled code returns null value when called by other exe. what may be the cause? – Ruwan Liyanage Aug 27 '20 at 08:23
Fildor, Axel Kemper I think the caller exe is exiting before the code executes. What may be the alternative methods? – Ruwan Liyanage Aug 27 '20 at 08:44
