c# - 一段时间后如何隐藏微调器？

Question

我想加载一个微调器并在一段时间后(大约 3、4 秒)隐藏它。我该怎么做？

   <StackPanel Grid.ColumnSpan="5" Grid.RowSpan="10" Background="White"Name="spinner">
   <fa:ImageAwesome Width="80" Icon="Spinner" Spin="True" SpinDuration="2" />
   </StackPanel>

这是一个纯 XAML 解决方案，没有任何代码:

<StackPanel ...>
    <StackPanel.Triggers>
        <EventTrigger RoutedEvent="Loaded">
            <BeginStoryboard>
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility">
                        <DiscreteObjectKeyFrame KeyTime="0:0:3"
                                                Value="{x:Static Visibility.Collapsed}"/>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </StackPanel.Triggers>

    <fa:ImageAwesome .../>
</StackPanel>
