WPF：如何定义用于在XAML中使用的集合

Question

我想定义这样的东西

<myCustomControl>
  <myCustomControl.Images>
     <Image
        Source="{StaticResource LockedIcon16}" />
     <Image
        Source="{StaticResource UnlockedIcon16}"/>
  <myCustomControl.Images>
<myCustomControl/>

我需要哪些属性定义才能使该集合（图像）发生？

System.Windows.Controls.Image 应该这样做。

尚未测试，但应该起作用。

public class myCustomControl {
  //...
    public ObservableCollection<Image> Images {
        get { return (ObservableCollection<Image>)GetValue(ImagesProperty); }
        set { SetValue(ImagesProperty, value); }
    }

    // Using a DependencyProperty as the backing store for Images.  This enables animation, styling, binding, etc...
    public static readonly DependencyProperty ImagesProperty =
        DependencyProperty.Register("Images", typeof(ObservableCollection<Image>), typeof(myCustomControl), new PropertyMetadata(null));
}
