Application.Exit

Question

Hello everyone,

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

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);
}
