图像控制异步 [英] Image Control asynchronous
问题描述
我有我希望它在网络上异步加载图像的图像控制。我看到一些样品code在网络上说是这样的：
I have an image control that I want it to load the image asynchronously over the network. I see some sample code in the network saying something like:
＆lt;图像的HorizontalAlignment =左HEIGHT =118保证金=2,8,0,0VerticalAlignment =评出的WIDTH =167X：NAME =ImageThumbnail来源={结合SummaryImageLink，IsAsync = TRUE}/＆GT;
然而，在 Windows Phone 7的，我找不到这样的事情。有谁知道一个办法做到这一点没有我不得不code有很多我自己
However, in Windows Phone 7, I cannot find anything like that. Does anybody know a way to do that without I have to code a lot myself
推荐答案
不幸的是，你将不得不写，或包括多个code自己做这个正常。我第一次下载后的目标类似的解决方案来缓存图像。图片缓存类是通过访问的IValueConverter，所以一旦你已包括相应的code，你只需要Image对象上添加装饰：
Unfortunately you are going to have to write, or include, more code yourself to do this properly. I have a similar solution with the goal to cache images after the first download. The image cache class is accessed via a IValueConverter, so once you have included the appropriate code, you only have to add a decorator on the Image object:
<Image Source="{Binding ElementName=ImageSource, Path=Text, Converter={StaticResource imageCacheConverter}}" Width="200" />
