Application.Exit

Question

I am using VSTS 2008 + .Net 3.5 + C# to develop Windows Forms application. My confusion is, seems Application.Exit does not force application to terminate? If not, which method should I call to make application terminate?

EDIT 1:

Normally the main method is like this, how to exit Main function gracefully without calling Environment.Exit?

    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        try
        {
            Application.Run(new Form1());
        }
        catch (Exception ex)
        {
            Console.WriteLine (ex.Message);
        }
    }

thanks in advance, George

Answer 1

Application.Exit really just asks the message loop very gently.

If you want your app to exit, the best way is to gracefully make it out of Main , and cleanly close any additional non-background threads.

If you want to be brutal... Environment.Exit or Environment.FailFast ? note this is harsh - about the same as killing your own Process .

Answer 2

Try the following:

Process.GetCurrentProcess().Kill();

Environment.Exit doesn't work with Winforms and Environment.FailFast throws its own exception.

Answer 3

If your application does not exit gracefully when you call Application.Exit there is (obviously) something that prevents it from doing so. This can be anything from a form setting e.Cancel = true in the FormClosing event, to a thread that is not a background thread that is still running. I would advice you to carefully research exactly what it is that keeps your process alive, and close that in a nice manner. That should make your application close nicely as well.

Typically, in a winforms application, it should be sufficient to close the main form.

I use

if (System.Windows.Forms.Application.MessageLoop)
{
   // Use this since we are a WinForms app
   System.Windows.Forms.Application.Exit();
}
else
{
   // Use this since we are a console app
   System.Environment.Exit(1);
}

Answer 5

I had the same problem when I discovered opening a new form/window within the program, and only HIDING that second form (not closing it), would prevent the main form from properly quitting via Application.Exit();

There are two solutions in this case. First is to simply use Close() on the main form instead of Application.Exit(). Second solution is to use the following code:

if (secondForm != null && !secondForm.IsDisposed) secondForm.Dispose();

我发现你只需要做的就是做application.exit而你所要做的就是把它放到End中就足够了，End命令关闭它
