c# - UWP 按钮在鼠标悬停时改变颜色

Question

我正在尝试创建一个 UWP 按钮，当鼠标指针悬停在它上面时，它会改变背景颜色。我遇到的麻烦是，默认情况下，它似乎已经这样做了，但不是我想要的颜色。当我将鼠标悬停在我的红色按钮上时，它会变成默认的灰色，然后在我鼠标移开时返回。我用 C# 编写了代码，试图在我将鼠标悬停在它上面时让它变成蓝色

private void button_PointerEntered_1(object sender, PointerRoutedEventArgs e)
    {
        button.Background = new SolidColorBrush(Windows.UI.Color.FromArgb(255, 0, 0, 255));
    }

    private void button_PointerExited_1(object sender, PointerRoutedEventArgs e)
    {
        button.Background = new SolidColorBrush(Windows.UI.Color.FromArgb(255, 255, 0, 0));
    }

下面是按钮的 XAML 代码

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <Button x:Name="button" 
                Content="Button" 
                HorizontalAlignment="Left" 
                Margin="417,188,0,0" 
                VerticalAlignment="Top" 
                Height="230" 
                Width="461" 
                FontSize="72" 
                ManipulationMode="None" 
                PointerEntered="button_PointerEntered_1" 
                PointerExited="button_PointerExited_1">
            <Button.Foreground>
                <SolidColorBrush Color="Black"/>
            </Button.Foreground>
            <Button.Background>
                <SolidColorBrush Color="Red"/>
            </Button.Background>
        </Button>

    </Grid>

实现它的最简单方法是覆盖按钮字典中的资源(针对您想要的主题)
您可以更改名为 Button<Property>PointerOver 的资源键的值为了使效果起作用:

<Button Background="Red" Foreground="Black"> <!-- These are only applied when your button is not being hovered-->
    <Button.Resources>
        <ResourceDictionary>
            <ResourceDictionary.ThemeDictionaries>
                <ResourceDictionary x:Key="Dark">
                    <SolidColorBrush x:Key="ButtonForegroundPointerOver" Color="Red"/>
                    <SolidColorBrush x:Key="ButtonBackgroundPointerOver" Color="Black"/>
                </ResourceDictionary>
                <ResourceDictionary x:Key="Light">
                    <SolidColorBrush x:Key="ButtonForegroundPointerOver" Color="Red"/>
                    <SolidColorBrush x:Key="ButtonBackgroundPointerOver" Color="Black"/>
                </ResourceDictionary>
            </ResourceDictionary.ThemeDictionaries>
        </ResourceDictionary>
    </Button.Resources>
</Button>

Here is an example on how this is done在 Microsoft 官方文档中，结果如下:
