C# 如何在WPF中使用StackPanel.FindName？

我有一个堆栈面板，里面有一组四个图像按钮。当我尝试按图像按钮的名称搜索时，返回空值。我的代码有什么问题

XAML:

<StackPanel x:Name="swatchClearStackPanel" Orientation="Vertical" Grid.Column="1" Grid.Row="2" Margin="0,10,0,0" HorizontalAlignment="Left" VerticalAlignment="Bottom">
     <imgbutton:ImageButton x:Name="ClearSwatchColor1" Grid.Row="0" Grid.Column="2" Style="{DynamicResource ButtonClearSwatchColor}" Margin="5,8,5,5" HorizontalAlignment="Left"  Visibility="Hidden" Click="ClearSwatchColor_Click"  />
     <imgbutton:ImageButton x:Name="ClearSwatchColor2"  Grid.Row="0" Grid.Column="2" Style="{DynamicResource ButtonClearSwatchColor}"  Margin="5,18,5,5" HorizontalAlignment="Left"  Visibility="Hidden" Click="ClearSwatchColor_Click"/>
     <imgbutton:ImageButton x:Name="ClearSwatchColor3"  Grid.Row="0" Grid.Column="2" Style="{DynamicResource ButtonClearSwatchColor}"  Margin="5,18,5,5" HorizontalAlignment="Left"  Visibility="Hidden" Click="ClearSwatchColor_Click"/>
     <imgbutton:ImageButton x:Name="ClearSwatchColor4"  Grid.Row="0" Grid.Column="2" Style="{DynamicResource ButtonClearSwatchColor}" Margin="5,20,5,5" HorizontalAlignment="Left"  Visibility="Hidden" Click="ClearSwatchColor_Click"/>
</StackPanel>

既然您已经有了所需ImageButton的名称，为什么还要使用FindName？为什么您不能通过名称直接访问它

ClearWatchColor1.xxx

您的代码看起来不错，应该可以使用。你是在UI呈现之前调用它吗？也许你没有很好地表达这个问题。附加组件定义IMGButton如果在构造函数中使用，请在初始化组件后尝试访问。

var swatchClearButton = swatchClearStackPanel.FindName("ClearSwatchColor1");
