wpf-controls - 在 wpf 中以编程方式创建进度条

Question

我正在尝试在 wpf 中以编程方式创建进度条。到目前为止，这是我的代码

infoWindow = new Window();
infoWindow.WindowStartupLocation = WindowStartupLocation.CenterScreen;
infoWindow.SizeToContent = SizeToContent.WidthAndHeight;
infoWindow.Title = "Please wait...";

StackPanel stackPanel = new StackPanel();
stackPanel.Orientation = Orientation.Vertical;

ProgressBar progressBar = new ProgressBar();
progressBar.IsIndeterminate = true;
progressBar.Margin = new Thickness(10,0,10,10);
progressBar.Visibility = Visibility.Visible;
progressBar.Height = 25;
progressBar.FlowDirection = FlowDirection.LeftToRight;
progressBar.Foreground = System.Windows.Media.Brushes.Green;
progressBar.Background = System.Windows.Media.Brushes.Red;

stackPanel.Children.Add(progressBar);

infoWindow.Content = stackPanel;
infoWindow.Show(); 

我从中得到的是一个红色的进度条。但是没有动画像我们复制文件时那样发生。（我不想显示任何进展，只是以圆形方式穿过整个条带的光）。有什么想法我在这里想念的吗？
