wpf c# 检查网格中是否存在对象
大家好 我有一个问题
，是否有一个由 xaml 构建的网格，并且在该网格中，有许多由 C# 语法创建的对象。
如何访问该对象或知道该网格中有对象。
例如。在我的网格中，首先是空的，但是当我单击网格站点外的按钮后，会创建一些对象，例如文本块和列表框。不，我还有另一个按钮来检查并列出该网格中的对象。这是 xaml 代码：
<Grid x:Name="LayoutRoot">
<TabControl Margin="0,0,0,141">
<TabItem Header="TabItem">
<Grid Background="#FFE5E5E5"/>
</TabItem>
</TabControl>
<Button Content="Create Object" HorizontalAlignment="Left" Margin="87,0,0,54.04" VerticalAlignment="Bottom" Width="105"/>
<Button Content="check object" HorizontalAlignment="Right" Margin="0,0,237,54.04" VerticalAlignment="Bottom" Width="75"/>
<ListBox HorizontalAlignment="Right" Height="82" Margin="0,0,100,21" VerticalAlignment="Bottom" Width="101"/>
</Grid>
请帮助我

这可能不是最容易做的事情，但它已经写好了，所以您需要了解它的工作原理并使用它：Linq to Visual Tree

它对我正在从事的一个项目有帮助。
