我在哪里可以找到Silverlight标准加载动画？

Question

对于我的生活，我似乎无法找到标准的Silverlight加载动画，一个旋转球（嗯......只是看起来不合适/听起来不对......）是...这个在SDK的某个地方？

是否有任何可以在Silverlight中使用繁忙动画的网站？

Answer 1

标准加载屏幕实际上嵌入在原生Silverlight代码中，因为它在Core CLR加载之前可用，并且实际上不是ProgressBar模板或类似的东西。

这意味着您需要将其嵌入到您的应用程序中，无法在XAML中直接引用它或在代码中提取它。

我做了一些环顾四周，并找到了它。可以更新LoadingText命名文本块以将0％更改为有用的内容。

Answer 2

我认为这正是你正在寻找的东西（即：旋转的蓝色球......嗯，这听起来也不是很好）：

首先，从this link下载图像。将“assets”文件夹添加到“ClientBin”文件夹中。

接下来，将以下画布添加到您的XAML

<Canvas x:Name="progressIndicator" Opacity="1" Canvas.Left="480" Canvas.Top="230" Width="50" Height="30">
        <Canvas.Resources>
            <Storyboard x:Name="loadingIndicator" Duration="00:00:0.03" Completed="loadingIndicator_Completed">
            </Storyboard>
    </Canvas.Resources>
</Canvas>

最后，将以下内容添加到

后面的XAML代码中

        const int TotalImages = 101;
        int CurrentImage = 0;

        public MainPage()
        {
            InitializeComponent();
            PreLoadImages();
            this.loadingIndicator.Begin();
        }

        public void PreLoadImages()
        {
            Image img = new Image();
            img.Name = "ll_0";
            img.Opacity = 1;
            img.Source = new System.Windows.Media.Imaging.BitmapImage(new Uri("/assets/images/loader_loop_00000.png", UriKind.Relative));
            progressIndicator.Children.Add(img);
            for(int i = 1;i <= TotalImages;i++) {
                img = new Image();
                img.Name = "ll_" + i.ToString();
                img.Opacity = 0;
                img.Source = new System.Windows.Media.Imaging.BitmapImage(new Uri("/assets/images/loader_loop_00" + i.ToString("000") + ".png", UriKind.Relative));
                img.Width = 30;
                img.Height = 30;
                progressIndicator.Children.Add(img);
            }
        }

        private void loadingIndicator_Completed(object sender, EventArgs e)
        {
            Image currentImage = (Image)FindName("ll_" + CurrentImage.ToString());
            currentImage.Opacity = 0;
            CurrentImage++;
            if (CurrentImage >= TotalImages) { 
                CurrentImage = 0; 
            }
                currentImage = (Image)FindName("ll_" + CurrentImage.ToString());
                currentImage.Opacity = 1;

                loadingIndicator.Begin();

        }
