问题描述

如何访问WPF Canvas类的子项？

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

这是一个很酷的类，我喜欢如何添加孩子。但是一旦他们在那里，你怎么看他们阅读他们的状态和内容。我知道这很容易，如果你把孩子们在XAML。但是，如果您在运行时动态添加子对象到画布呢？

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 Children 属性。

编辑：下面是一个迭代子项并通过索引获取的示例：

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];
