是否允许在不关闭C＃中的应用程序的情况下关闭Form1？

Question

Ok, form1 is my "intro". I need form1 to close and form2...When it closes, the Whole application closes. I am new at this, so i do not know how to explain my problems well...If you have any question..please ask... :)

Answer 1

Another solution which I use when I need to have a splash screen before showing the main form is to use this solution:

In the Main function of your Program class you usually have something like that:

    [STAThread]
    static void Main(string[] ps)
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());

    }

The Application.Run bind the application to a form so that when the form closes, the application exit. If you want to show form 2 before form 1, you can do this:

    [STAThread]
    static void Main(string[] ps)
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Form1 splash = new Form1();
        splash.ShowDialog();
        Application.Run(new Form2());
    }

This new code will show form2. and after you close form2, it will show form1. Closing Form1 will exit the application.

Usually the Splash window is created in another thread, leaving the main thread loading the data it needs.

Answer 2

除了关闭，您还可以隐藏From1。

Form1.hide = true

Answer 3

You should override the OnClosing method in the form...

protected override void OnClosing(CancelEventArgs e)
{
     e.Cancel = true;
     this.Hide();
}
