WPF 踩坑笔记10 ListBox异步动态加载

1.当ListBox内容很多时 可使用异步动态加载友好显示

 private ObservableCollection<ImageInfo> detailImages = new ObservableCollection<ImageInfo>();
 public ObservableCollection<ImageInfo> DetailImages
 {
     get { return detailImages ; }
     set { SetProperty(ref detailImages , value); }
 } 

...

for (int i = 0; i < 10000; i++)
{
    DispatherHelper.Dispatcher.Invoke(DispatcherPriority.Background, (Action)(() =>
    {
        DetailImages.Add(image);
    }));
}
