按下最小化时程序关闭

我有两个函数

private void Main_Resize(object sender, EventArgs e)
{
    if (FormWindowState.Minimized == WindowState)
    {
        Hide();
        notification.BalloonTipTitle = "Smart Connection";
        notification.BalloonTipText = "Smart Connection has been minimized to the taskbar.";
        notification.ShowBalloonTip(3000);
    }
}

对于我的Form最小化和

private void Main_FormClosing(object sender, FormClosingEventArgs e)
{
    if (connected)
    {
        if (MessageBox.Show("Are you sure?",
               setting.Split(':')[0],
                MessageBoxButtons.YesNo,
                MessageBoxIcon.Warning,MessageBoxDefaultButton.Button2) == DialogResult.No)
        {
            e.Cancel = true;
        }
    }
}

对于我的Form关闭事件

但当我按下最小化按钮时，MessageBox会过来说"你确定吗？"

对于"是"answers"否"按钮，当我按下其中任何一个时，程序都将关闭。

但是，为什么它们是针对两个不同事件的两个不同功能？

我发现为什么this.Hide()关闭我的猪肉，因为我的飞溅形式

这是我的斜杠

public partial class Splash : DevComponents.DotNetBar.Metro.MetroForm
{
    public Splash()
    {
        InitializeComponent();
    }
    private void timer_Tick(object sender, EventArgs e)
    {
        progress.Value += 2;
        if (progress.Value == progress.Maximum)
        {
            this.Hide();
            timer.Stop();
            Main f = new Main();
            f.ShowDialog();
            this.Close();
        }
    }
}

我的Program.cs是

 static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        bool createdNew;
        using (var mutex = new System.Threading.Mutex(true, "SmartConnection", out createdNew))
        {
            if (createdNew)
            {
                Application.Run(new Splash());
            }
            else
            {
                MessageBox.Show("some text");
            }
        }
    }

private void Main_FormClosing(object sender, FormClosingEventArgs e)
