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();
                }));
            }
        }
    }
