C# 使用窗口作为加载屏幕

我无法直接找到任何东西来解决我的这个问题。 我正在尝试制作一个动画gif作为加载屏幕，用于我的程序中加载时间很长的几个地方

我让它在创业公司工作，但一旦我试图再次使用它，它崩溃了我的程序。我从来没有完全理解过整个线程，所以我的代码中可能有错误

[编辑]我想要的是当一个沉重的方法运行时，比如说当它从数据库或一个简单的线程获取所有数据时，启动加载屏幕。睡眠（#######），此时我想要一个动态的splashscreen运行，这个屏幕是我的第二个窗口，上面有一个动画gif。我打开了窗户，打开了窗户

我要检查的窗户是空的

PS：如果你知道任何更好的解决方案，它会像我在这里尝试做的一样，请随时提供它的链接

[Edit]我更改了，所以我不再使用app.xaml，因为我不想在启动时使用它，所以我将代码移到将要使用它的主窗口中

现在它不再崩溃了，但它只是第一次显示我的窗口，任何超出此范围的内容都不会显示任何内容

[Edit-2]我进行了一些测试，并决定让窗口看起来更好，这时我遇到了确切的问题所在。 在我将上面的代码移到Main中，而不是在App.xaml中运行之后，似乎上面的代码现在可以正常工作了。我取下了钥匙

    public void LoadStart()
    {
        Dispatcher.Invoke((Action)delegate()
        {
            //this.UpdateMessageTextBox.Text = message;
        });
    }

也是从Loading.xaml开始的，因为我没有任何东西可用于if。在我下面的示例中，它的用途是更新页面上的标签

问题似乎出在我安装的软件包上，这些软件包本应向我显示动画gif

    <Image gif:ImageBehavior.RepeatBehavior="Forever" gif:ImageBehavior.AnimatedSource="/img/Animated_ARKA_Loading.gif" />

    public partial class App : Application

            private Thread SplashThread;
            protected override void OnStartup(StartupEventArgs e)
            {
                // ManualResetEvent acts as a block. It waits for a signal to be set.
                ResetSplashCreated = new ManualResetEvent(false);

                // Create a new thread for the splash screen to run on
                SplashThread = new Thread(ShowSplash);
                SplashThread.SetApartmentState(ApartmentState.STA);
                SplashThread.IsBackground = true;
                SplashThread.Name = "Splash Screen";
                SplashThread.Start();

                // Wait for the blocker to be signaled before continuing. This is essentially the same as: while(ResetSplashCreated.NotSet) {}
                ResetSplashCreated.WaitOne();
                base.OnStartup(e);
            }

仅仅添加一个splashscreen并不能解决这个问题，因为我一开始就这么做了，但是程序中的一些加载要花2个月的时间，所以Being能够看到移动的加载让用户明白，它实际上并没有卡住，只是一张没有动画的图片，上面说加载似乎也有点冻结。我有splashscreen作为备份，因为它已经正常工作了：）我遵循这一点是为了让它在第一时间起作用，嗯，我想你误解了我想要的：）博客很好。这适用于启动加载，您可以在其中动态更改其上的文本。我想要的是，当程序运行时，我点击一个按钮，然后它从数据库加载一吨，同时它将显示加载屏幕。我现在正试图从app.xaml中删除它，但仍然没有找到任何修复方法。我在atm上的位置显示第一次加载和第二次加载的时间，它的清空时间点是

OnStartup（）

returns您打开了两个窗口还是只有一个？换句话说，你的意图是显示一个启动屏幕；稍微关上它；然后打开

main窗口

？如果我在启动时运行，它会显示良好的屏幕，并在主窗口显示yes后关闭它。在发生这种情况时，只有一个页面是打开的。但就像我说的，这不是我想要的。我不知道，我在这里的帖子中添加了一些编辑字段，并更新了我的位置。似乎我必须找到另一种方式来显示Gif，我甚至可能会使用循环和一些线程。Sleep（#######）在4张图片之间切换以模拟动画，因为Gif无论如何只有4张图片长
