Start a new process and Killing the current process

Question

I want to start a new process B.exe from the current executing process A.exe.

And as soon as B.exe is launched I want to kill A.exe (the current executing process).

Though I can start B.exe I cannot close my current process i.e A.exe.

Code I use is:

//Start the BT Setup Process
ProcessStartInfo startInfo = new ProcessStartInfo(@"C:\TEST\B.exe");
Process.Start(startInfo);

//Terminate the FSA 
Process[] myProcess = Process.GetProcessesByName(Process.GetCurrentProcess().ProcessName);
foreach (Process process in myProcess)
{
    process.CloseMainWindow();
    //all the windows messages has to be processed in the msg queue
    //hence call to Application DoEvents forces the MSG
    Application.DoEvents();
}

Why not call your cleanup code manually and then call Kill? As others have mentioned you should look into why Application.Exit() doesn't work for you. — Mataniko, Dec 26 '12 at 05:58

Why do you want to close A from B while A cat start B and then close by itself?

Process.Start("A.exe");
Process.GetCurrentProcess().Kill(); // or Application.Exit(); or anything else

If you're falling into this quest of starting a process, and kill your own process after, use Environment.Exit(0), not Application.Exit().

The application will not exit if there are any active foreground threads; Process.GetCurrentProcess().Kill(); seems more deterministic. – Erwin Mayer Nov 01 '15 at 19:14

This is very important... because, there's times where you do not want to kill threads... right? And sometimes you do! – Fabiano Cores Oct 08 '16 at 17:15

I know this is old but in .net 4.0 you can do

ProcessStartInfo startInfo = new ProcessStartInfo(@"C:\TEST\B.exe");
startInfo.UseShellExecute = true;//This should not block your program
Process.Start(startInfo);

Then Application.Exit or whatever I tested with a winforms application using the close form method after launching a console app that just blocks on Console.readline();

Try Process.Kill() instead of Process.CloseMainWindow().

I do not want to use Process.Kill() as it doesnt call my cleanup code – srivatsa Nov 25 '10 at 16:17

If you just want to close the current process you should be able to just call Application.Exit rather than looping through and closing processes.

Using Application.Exit hangs my A.exe application. That is the reason i use Process.CloseMainWindow() – srivatsa Nov 25 '10 at 16:17

@srivatsa: If calling `Application.Exit` in your process makes it hang, then I'd say that it might be worth trying to find out why, that might automatically answer your question above as well. – Hans Olsson Nov 25 '10 at 16:35
