Question

I am writing the update system for my application and I need to shutdown the application to overwrite the exe but after it shuts down I need to run the update executable, how can I do this?

Answer 1

Could you just start the updater using Process.Start and have it wait until your main program closes? I think that would be the easiest solution.

Or you could have a separate launcher program that will check for updates and update before launching the main application. But this leads to the same problem if you have to update the launcher.

Along the lines of this:

static void Main(string[] args) {   var haveToUpdate = ...;   if (haveToUpdate)   {     Process.Start('update.exe');     Environment.Exit(0);   } }  static void Main(string[] args) {   var processes = Process.GetProcessesByName('program.exe');    if (processes.Length > 1)     throw new Exception('More than one program.exe running');   else if (processes.Length == 0)     Update();   else     processes[0].Exited += new EventHandler(Program_Exited); }  static void Program_Exited(object sender, EventArgs e) {   Update(); }  static void Update() {   // ... }
