我正在尝试创建按钮模板。一切都有效，除了当我将鼠标移到按钮上时，文本的颜色应该变为白色。 XAML代码：
<!--Control colors.-->
<Color x:Key="ControlNormalColor">#FFFFFF</Color>
<Color x:Key="ControlMouseOverColor">#999999</Color>
<Color x:Key="DisabledControlColor">#FFFFFF</Color>
<Color x:Key="DisabledForegroundColor">#999999</Color>
<Color x:Key="ControlPressedColor">#999999</Color>
<!-- FocusVisual -->
<Style x:Key="ButtonFocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Border>
<Rectangle Margin="2" StrokeThickness="1" Stroke="#60000000" StrokeDashArray="1 2" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<!-- Button -->
<Style TargetType="Button">
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="OverridesDefaultStyle" Value="true" />
<Setter Property="FocusVisualStyle" Value="{StaticResource ButtonFocusVisual}" />
<Setter Property="MinHeight" Value="29px" />
<Setter Property="MinWidth" Value="103px" />
<Setter Property="FontFamily" Value="Century Gothic" />
<Setter Property="FontSize" Value="20" />
<Setter Property="Foreground" Value="#999999" />
<Setter Property="FontWeight" Value="Bold"></Setter>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border TextBlock.Foreground="{TemplateBinding Foreground}" x:Name="Border">
<Border.Background>
<SolidColorBrush Color="{DynamicResource ControlNormalColor}" />
</Border.Background>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="0:0:0.5" />
<VisualTransition GeneratedDuration="0" To="Pressed" />
</VisualStateGroup.Transitions>
<VisualState x:Name="Normal" />
<VisualState x:Name="MouseOver">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)"
Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource ControlMouseOverColor}" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)"
Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource ControlPressedColor}" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Disabled">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)"
Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource DisabledControlColor}" />
</ColorAnimationUsingKeyFrames>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(TextBlock.Foreground).(SolidColorBrush.Color)"
Storyboard.TargetName="Border">
<EasingColorKeyFrame KeyTime="0" Value="{StaticResource DisabledForegroundColor}" />
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<ContentPresenter Margin="2"
HorizontalAlignment="Center"
VerticalAlignment="Center"
RecognizesAccessKey="True" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我的问题是，我必须做什么才能让按钮中的文字在鼠标悬停时变为白色？此代码是从Internet复制的。我是WPF世界的新手。虽然我理解这段代码正在进行中，但我对WPF的了解有限。

你必须在MouseOver VisualState中再添加一个ColorAnimationUsingKeyFrames来更改鼠标悬停时的前景颜色，你可以使用下面的代号
<Color x:Key="ControlNormalColor">#FFFFFF</Color>
<Color x:Key="ControlMouseOverColor">#999999</Color>
<Color x:Key="DisabledControlColor">#FFFFFF</Color>
<Color x:Key="DisabledForegroundColor">#999999</Color>
<Color x:Key="ControlPressedColor">#999999</Color>

通过在样式中使用触发器我们可以得到它。鼠标悬停我们可以在setter中设置背景颜色
<Button Content="Button" HorizontalAlignment="Left" VerticalAlignment="Bottom" Width="50" Height="50" HorizontalContentAlignment="Left" BorderBrush="{x:Null}" Foreground="{x:Null}" Margin="50,0,0,0">
<Button.Style>
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="DarkGoldenrod"/>
</Trigger>
</Style.Triggers>
</Style>
</Button.Style>
</Button>
