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(); })); } } } 启动页面
