How can I make a Winforms form terminate the application?

I am coding Winforms in C#. I want to set up my program so that if a form is closed, the program will terminate or stop. I already know how to select a form that will be opened first.

This is the code in my program.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Windows.Forms;

namespace MainMenu
    static class Program
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        static void Main()
            Application.Run(new Login());

I want to set up my login.cs form so that if that form is closed, the program will terminate. Is this possible?


To do something when a form is closed, you need to handle the FormClosing event. Within your event handler, call Application.Exit() to terminate the application.

Using the model in the answer linked above (but in C#), use this event handler:

private void Form_Closing(Object sender, FormClosingEventArgs e)

To add the handler, simply register the method to the event as such in your form class (based on this discussion from MSDN):

this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(Form_Closing);
