Question

I want to build my application with the function to restart itself. I found on codeproject

ProcessStartInfo Info=new ProcessStartInfo();
Info.Arguments="/C choice /C Y /N /D Y /T 3 & Del "+
               Application.ExecutablePath;
Info.WindowStyle=ProcessWindowStyle.Hidden;
Info.CreateNoWindow=true;
Info.FileName="cmd.exe";
Process.Start(Info); 
Application.Exit();

This does not work at all…
And the other problem is, how to start it again like this?
Maybe there are also arguments to start applications.

I use similar code to the code you tried when restarting apps. I send a timed cmd command to restart the app for me like this:

ProcessStartInfo Info = new ProcessStartInfo();
Info.Arguments = "/C ping 127.0.0.1 -n 2 && \"" + Application.ExecutablePath + "\"";
Info.WindowStyle = ProcessWindowStyle.Hidden;
Info.CreateNoWindow = true;
Info.FileName = "cmd.exe";
Process.Start(Info);
Application.Exit(); 

The command is sent to the OS, the ping pauses the script for 2-3 seconds, by which time the application has exited from Application.Exit(), then the next command after the ping starts it again.

Note: The \" puts quotes around the path, incase it has spaces, which cmd can’t process without quotes.

Hope this helps!
