如何访问一个WPF Canvas类的孩子呢？

How do you access the children of a WPF Canvas class?

这是一个很酷的类，我喜欢你如何能增加孩子。但是，一旦他们在那里，怎么你看他们阅读他们的状态和内容。我知道，如果你把孩子XAML很容易。但是，如果你在运行时动态添加的孩子在画布？

It is a cool class and I like how you are able to add children. But once they are there, how to you look at them for reading their state and content. I know it is easy if you put the children in XAML. But what if you have added children to the canvas dynamically at run time?

推荐答案

您可以使用儿童财产。

编辑：这是迭代的孩子，通过索引获得的一个例子：

Here is an example of iterating over the children and getting one by index:

foreach (UIElement child in canvas.Children)
{
    // ...
}
// Or: 
int index = 0;
var childByIndex = canvas.Children[index];
