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();
                }));
            }
        }
    }
