推荐答案

DimeCasts.net 在 http://www.dimecasts.net/Casts/CastDetails/174

There's a good screencast on different ways of navigating between pages (and passing values) from DimeCasts.net at http://www.dimecasts.net/Casts/CastDetails/174

作为执行此操作的一种方法(并假设图像在 ListBox 中)的示例，将以下内容添加到 SelectionChanged 事件.

As an example of one way of doing this (and assuming the images were in a ListBox) would be to add the following to the SelectionChanged event.

private void OnSelectedImageChanged(object sender, SelectionChangedEventArgs e)
{
  NavigationService.Navigate(new Uri(string.Format("/image/{0}", HttpUtility.UrlEncode(((sender as ListBox).SelectedItem as PhotoViewModel).uri)), UriKind.Relative));
}

以上假设一个适当映射的路线，如:

The above assumes an appropriately mapped route like:

<nav:UriMapping Uri="/image/{image}" MappedUri="/Image.xaml?u={image}" />

并且原始列表框绑定到 PhotoViewModel 对象的 uri 属性.

and that the original listbox was bound to the uri property of a PhotoViewModel object.

希望通过观看截屏视频可以更清楚地了解上述任何内容.

Hopefully, watching the screencast should make any of the above clearer.
