I am trying to reproduce this with gtk#, how can I get the list of compatible extention with a specific file ? (in my case .cpp, .hpp)

I tried this :

Process.Start(@"C:\foo.jpg");

but it's only opens the default app.

    if you want an open with native dialogue: https://stackoverflow.com/questions/4726441/how-can-i-show-the-open-with-file-dialog If you on the other hand want the individual program names etc. you'd probably have to read them from the regestry under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\ .jpg\OpenWithList - thats for windows only obviously, but since you tagged this mono i thought i'd mention it – T.Schwarz Jul 28 '21 at 10:09
  • Gnome registers file types and their compatible applications in the so called MIME Database, https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/desktop_migration_and_administration_guide/file_formats so you can get started from there. – Lex Li Jul 28 '21 at 14:37
  • Thank you, I will take a look – user123458431 Jul 29 '21 at 09:57
