app.xaml 中的 application_exit 和 session_ending 事件无济于事。
有什么办法可以做到这一点?
XBAP 应用程序忽略 session_ending 事件但是 Exit 事件是,但我看不到在此事件中取消退出的方法。但是,为什么不让您的退出按钮调用一个方法来请求关闭,如果是,请在此处明确关闭应用程序,或者不
[DllImport("user32", ExactSpelling = true, CharSet = CharSet.Auto)]
private static extern IntPtr GetAncestor(IntPtr hwnd, int flags);
[DllImport("user32", CharSet = CharSet.Auto)]
private static extern bool PostMessage(IntPtr hwnd, int msg, IntPtr wparam, IntPtr lparam);
private void exitButton_Click(object sender, RoutedEventArgs e)
{
if (MessageBox.Show("Are you Sure you want to Exit?", "Confirm", MessageBoxButton.OKCancel) == MessageBoxResult.OK)
{
// This will Shut entire IE down
WindowInteropHelper wih = new WindowInteropHelper(Application.Current.MainWindow);
IntPtr ieHwnd = GetAncestor(wih.Handle, 2);
PostMessage(ieHwnd, 0x10, IntPtr.Zero, IntPtr.Zero);
// Singularly will just shutdown single tab and leave white screen, however with above aborts the total IE shutdown
// and just shuts the current tab
Application.Current.Shutdown();
}
}
你还需要这些
使用 System.Windows.Interop;使用 System.Runtime.InteropServices;
