Question

I have a parent program that calls a worker console app when and update is found to update the files, this application gets the process ID from the parent via arguments and then calls WaitForExit().
What I wish to know is what would be the best way of then restarting that process, would simply calling Proc.Start() be the best way of doing this?
Ex:

static void Main(string[] args)
{
    if (args.Length == 2)
    {
        int ParentID = Convert.ToInt16(args[1]);
        Process ParentProc = Process.GetProcessById(ParentID);
        ParentProc.WaitForExit();
        Console.WriteLine(UpdateHandler.GetUpdates(
            Path.GetDirectoryName(ParentProc.MainModule.FileName), args[0]));
        ParentProc.Start();
    }
    else
        Console.WriteLine("Error: Invalid number of arguments.");
}

Or should I create a new process to launch it (I would assume using ParentProc.MainModule.FileName)

I would also like to know if there is a managed way to get the parent process not via arguments?

Thanks 🙂
