I have created one Python exe which is reading data from Config.Json. Now I want to call this exe from C# console application, but I am getting an error stating

HTML

<pre>Traceback (most recent call last):
  File "file.py", line 552, in <module>
  File "file.py", line 12, in read_JSON
FileNotFoundError: [Errno 2] No such file or directory: 'config.json'
[456] Failed to execute script filePathExe

I am trying to run through below code:

C#

string appArgs = @"D:\appFolder\config.json";
string appPath = @"D:\appFolder\filePathExe.exe";
Process proc = new Process();
ProcessStartInfo si = new ProcessStartInfo(appPath, appArgs);
si.WindowStyle = ProcessWindowStyle.Normal;
si.Verb = "runas";             // UAC elevation required.
si.UseShellExecute = true;     // Required for UAC elevation.
proc.StartInfo = si;
proc.Start();
proc.WaitForExit();

Can someone please help, how can I run this?

What I have tried:

I have attached code above which I am using.

You sure whereever you are running the program/exe, file is present at the expected location?
FileNotFoundError: [Errno 2] No such file or directory: 'config.json'

yes, both files are at same location. Also exe is working fine when I am trying to run it individually but not working from C# console application.

That's a bit odd .. try adding Hide Copy CodeHide Copy Code

si.WorkingDirectory = @"D:\appFolder";

ie Hide Copy CodeHide Copy Code

si.WindowStyle = ProcessWindowStyle.Normal;si.WorkingDirectory = @"D:\appFolder";
si.Verb = "runas";             // UAC elevation required.

It would also be good to check the python code that made the exe to double-check it's using thr fully qualified path etc to the config file

As suggested by ZurdoDev although the OP has posted my comment ....

That's a bit odd .. try adding

si.WorkingDirectory = @"D:\appFolder";

making the code

si.WindowStyle = ProcessWindowStyle.Normal;
si.WorkingDirectory = @"D:\appFolder";
si.Verb = "runas";             // UAC elevation required.

As @Garth suggested above to add working directory,I added that and it worked for me. so code is:

C#

string appArgs = @"D:\appFolder\config.json";
string appPath = @"D:\appFolder\filePathExe.exe";
Process proc = new Process();
ProcessStartInfo si = new ProcessStartInfo(appPath, appArgs);
si.WindowStyle = ProcessWindowStyle.Normal;
si.WorkingDirectory = @"D:\appFolder";
si.Verb = "runas";             // UAC elevation required.
si.UseShellExecute = true;     // Required for UAC elevation.
proc.StartInfo = si;
proc.Start();
proc.WaitForExit();

Thanks,
