关闭启动表单时，如何防止应用终止？

关闭启动窗口时，会编写Program.cs中自动生成的代码来终止应用程序。您需要对其进行调整，以便仅在没有更多窗口可用时才终止。像这样：

    [STAThread]    static void Main() {        Application.EnableVisualStyles();        Application.SetCompatibleTextRenderingDefault(false);        var main = new Form1();        main.FormClosed += new FormClosedEventHandler(FormClosed);        main.Show();        Application.Run();    }    static void FormClosed(object sender, FormClosedEventArgs e) {        ((Form)sender).FormClosed -= FormClosed;        if (Application.OpenForms.Count == 0) Application.ExitThread();        else Application.OpenForms[0].FormClosed += FormClosed;    }
