Question

我想在WPF中移动一个Image控件（实际上，Image将从左向右移动然后向左移动到右移，循环重复此操作。），我想使用XAML来控制它。此外，我希望图像控件在引发MouseEnter事件时移动。以下是我在Grid中的图片：

<Window

    </Image>
</Grid>

我是WPF的新学员，AnyOne可以提供帮助吗？谢谢。实际上我在SOF中找到了一章：WPF. Easiest way to move Image to (X,Y) programmatically?

嗯，那不是我想要的。

我的答案如下：我们需要一个Canvas来包含图像，我们可以使用Canvas的“Left”属性来移动图像。

<Canvas x:Name="MyCanvas">
        <Canvas.Triggers>
            <EventTrigger RoutedEvent="FrameworkElement.Loaded">
                <BeginStoryboard >
                    <Storyboard Storyboard.TargetName="img1" Storyboard.TargetProperty="(Canvas.Left)">
                        <DoubleAnimation From="0" To="514" Duration="0:0:20" AccelerationRatio=".2" DecelerationRatio=".8" RepeatBehavior="23:59:59" AutoReverse="True"/>
                    </Storyboard>
                </BeginStoryboard>
            </EventTrigger>
        </Canvas.Triggers>

如何使用XAML移动图像？
