Question

我有一个带有这三个分开的东西的WPF应用程序：

启动画面
登录窗口
主窗口

当我打开应用程序时，首先会显示启动画面一段时间，然后进入登录窗口。用户登录成功后，启动画面将再次显示，最后进入主窗口。它是在处理线程吗？关于如何将这三件事联系在一起的任何建议？

Answer 1

您可以使用SplashScreen课程执行此操作。你必须在两个窗口的构造函数中显示/隐藏启动画面。

Public LoginWindow ()
{    
  //Show splash screen
  SplashScreen splashScreen = new SplashScreen("imageSource");
  splashScreen.Show(false, false);

  //Do any operation here

  //Closing the Splashscreen with fadding effect
  splashScreen.Close(TimeSpan.FromSeconds(1));

}

Public MainWindow ()
{
  //Show splash screen
  SplashScreen splashScreen = new SplashScreen("imageSource");
  splashScreen.Show(false, false);

  //Do any operation here

  //Closing the Splashscreen with fadding effect
  splashScreen.Close(TimeSpan.FromSeconds(1));
}

嗯，我认为这可能会对你有所帮助： - ＆GT; http://blog.dontpaniclabs.com/post/2013/11/14/Dynamic-Splash-Screens-in-WPF

您可以在加载任何内容时显示slapshScreen，或者只使用线程。

将以下代码添加到splash.xaml.cs类

的构造函数中

try
        {
            Task.Delay(2000).ContinueWith(_ =>
            {
                var frame = NavigationHelper.FindFrame(null, this);
                frame.Source = new Uri("../Pages/Login.xaml", UriKind.Relative);

            });
        }catch(Exception ee){

        }
