How can I programmatically close the WinForms application after a certain time?

I start my form in the usual way:

Application.Run(new MainForm());

I want it to open and run before a certain time, and then close. I tried the following, but to no avail:

(1) In the main method (there was an expression Application.Run ()), I enter the following AFTER Application.Run ()

while (DateTime.Now < Configs.EndService) { }

RESULT: he never hits.

(2) BEFORE STARTING Application.Run () I am launching a new background theme:

        var thread = new Thread(() => EndServiceThread()) { IsBackground = true };
        thread.Start();

where EndServiceThread:

    public static void EndServiceThread()
    {
        while (DateTime.Now < Configs.EndService) { }
        Environment.Exit(0);
    }

RESULT: vshost32.exe has stopped working with a failure.

(3) In the MainForm Tick event:

        if (DateTime.Now > Configs.EndService)
        {
            this.Close();
            //Environment.Exit(0);
        }

RESULT: vshost32.exe has stopped working with a failure.

What is the right way to achieve my goal? Again, I want to run the form, open it and run until a certain time (Configs.EndService), and then close.

Thanks Ben.

If you use System.Threading.Timer, you can use DueTimeto install the first time it starts, like the time when you want to close the application

new System.Threading.Timer((o) => Application.Exit(), null, (Configs.EndService - DateTime.Now), TimeSpan.FromSeconds(0));
Application.Run(new Form1());
