Recently being making a little utility app for transporting and playing local html5/jquery based presentation from pc to ipad etc, below are some snippets of code for starting stopping other apps such as chrome browser, cmd.exe, I did these in xamarin/mono really easily however the transfer to unity was a little taxing on the more involved processes, certainly adding /C before a command line argument was new to me, strangely. Below also includes some code for zipping files in unity3d using 7-zip of 7za.exe, although I’ve used internal .net libraries before sometime 7za for a unity windows stand alone solution is certainly quick and easy.
Unity3d/.Net c# code:-
