Ways to quit application after launching multiple winforms?

Let's say I launched multiples winforms from Program.cs with

Form1 form1 = new Form1();
form1.show();
Form2 form2 = new Form2();
form2.show();
Application.Run();

How do I quit application when all forms are closed by User ?

I can of course put Application.Exit() in FormClosed event but it's not very elegant I think. Are there other ways ?

Update: I mean it's not elegant to hard code each FormClosed each I have to add a new form. So is there a way I can HOOK ANY FormClosed event globally so that I can maintain the code in a central event handler without doing the PLUMBING BY HAND.

In some frameworks like Wordpress you can capture any event for any object globally I want the same kind of thing.

Application.Exit() is required in this case. Another approach is that you designate one of the forms as the "main window". And the app will terminate when it is closed:

 Application.Run(form1);

The .NET framework also supports a "when last window closes" shutdown mode. Check my code in this thread for the required code.

You can maintain a List of the forms that are open, and, each time a form is closed have it delete itself from that list and then check if the list is empty. If the list is empty, end the application.

Use Application.OpenForms to process all open forms and decide what to do with them. If you know which one should be saved - prompt the user, otherwise close it. And so on.
