wpf软件启动时，加载启动页面。软件初始化完成之后关闭页面。

App.xaml.cs代码 （实现加载页面功能）

public partial class App : Application    {        protected override void OnStartup(StartupEventArgs e)        {            var thread = new Thread(new ThreadStart(() =>            {                WpfApplication1.MainWindow.window = new Window1();                WpfApplication1.MainWindow.window.Show();                WpfApplication1.MainWindow.window.Activate();                System.Windows.Threading.Dispatcher.Run();            }));            thread.SetApartmentState(ApartmentState.STA);            thread.IsBackground = true;            thread.Start();            base.OnStartup(e);        }    }

MainWindow.cs

public partial class MainWindow : Window    {        public static Window1 window = null;        public MainWindow()        {            InitializeComponent();        }        private void Window_Loaded(object sender, RoutedEventArgs e)        {            Thread.Sleep(1000*10);            if (window != null)            {                window.Dispatcher.BeginInvoke((Action) (() =>                {                    window.Close();                }));            }        }    }
