通過該站點搜索，我發現了按下按鈕時如何在 WPF 中更改按鈕顏色。我不確定的是如何使它回到再次按下時會變回的位置。這是我的代碼：
<Button Margin="917,631,480.8,144.4" Background="Transparent" x:Name="blackCounter6" >
<Button.Resources>
<Style TargetType="{x:Type Button}">
<Style.Triggers>
<Trigger Property="IsPressed" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation Storyboard.TargetProperty="(Control.Background).(SolidColorBrush.Color)" To="Black"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
</Trigger>
</Style.Triggers>
</Style>
<Style TargetType="{x:Type Border}">
<Setter Property="CornerRadius" Value="50"/>
</Style>
</Button.Resources>
</Button>
未按 已 按
第一張圖片顯示了按下之前的按鈕，之后的第二張。再次按下時，我試圖將其還原。它是一個位于影像后面的控制元件，我使用了一個按鈕，因為我知道如何使它們變圓并像它一樣安裝在適當的位置。我也有可用于實作此目的的 C# 腳本。我假設我添加了某種功能以將其恢復到原始狀態？

“再次按下它會變回來”？我認為您更喜歡復選框而不是按鈕。您可以添加復選框樣式的觸發器作為打擊。
<Trigger Property="IsChecked" Value="True">
<Trigger Property="IsChecked" Value="False">
如果您需要 Storyboard.The 觸發器 IsChecked=False 是不必要的。您可以在 <Trigger.EnterActions> 之后添加 <Trigger.ExitActions>。另外，<Trigger.ExitActions> 和<Trigger.EnterActions> 通常應該作為一對使用。
復選框的代碼。特別是關于Checkbox的模板，可以從xaml視圖->檔案大綱->找到Checkbox控制元件->右鍵->編輯模板->編輯副本->確定，就可以得到CheckBox的完整模板代碼.
<ControlTemplate TargetType="{x:Type CheckBox}">
<Grid x:Name="templateRoot" Background="Transparent" SnapsToDevicePixels="True">
<Border x:Name="checkBoxBorder" CornerRadius="10" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="1" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
<Grid x:Name="markGrid">
<Ellipse x:Name="excontent" Margin="5" Panel.ZIndex="9" Fill="Blue" Stroke="{TemplateBinding Foreground}"/>
<Ellipse x:Name="content" Width="{TemplateBinding Width}" Height="{TemplateBinding Height}" Fill="{TemplateBinding Background}" Stroke="{TemplateBinding Foreground}"/>
</Grid>
</Border>
</Grid>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Trigger.EnterActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation Storyboard.TargetProperty="(Control.Background).(SolidColorBrush.Color)" To="Black"/>
</Storyboard>
</BeginStoryboard>
</Trigger.EnterActions>
<Trigger.ExitActions>
<BeginStoryboard>
<Storyboard>
<ColorAnimation Storyboard.TargetProperty="(Control.Background).(SolidColorBrush.Color)"/>
</Storyboard>
</BeginStoryboard>
</Trigger.ExitActions>
</Trigger>
</ControlTemplate.Triggers>

最簡單的解決方案是定義一種樣式并使用管理各種狀態的觸發器。
<Button Margin="917,631,480.8,144.4" Background="Transparent" x:Name="blackCounter6" >
<Button.Resources>
<Style TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}">
<Setter Property="Background" Value="{DynamicResource PrimaryApplicationColorBrush}"/> //Set your background
<Setter Property="Foreground" Value="{DynamicResource ApplicationForegroundColorBrush}"/> //Set your default foregraound color
<Setter Property="BorderBrush" Value="{StaticResource ButtonBorderBrush}"/> //Set your border brush color
<Setter Property="FontFamily" Value="{StaticResource FontNormal}"/> //Set your desired font
<Setter Property="FontSize" Value="{StaticResource FontSizeLarge}"/> //Set your font size
<Setter Property="Stylus.IsPressAndHoldEnabled" Value="False" />
<Setter Property="FocusVisualStyle" Value="{x:Null}"/>
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border CornerRadius="4"
Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}"
Padding="{TemplateBinding Padding}">
<ContentPresenter RecognizesAccessKey="True"
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Background" Value="{StaticResource ButtonPressedBackground}"/> //Set your background when the button is pressed
<Setter Property="BorderBrush" Value="{StaticResource ButtonPressedBorderBrush}" /> //Set your BorderBrush when the button is pressed
</Trigger>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="BorderBrush" Value="{StaticResource ButtonMouseOverBorderBrush}" /> /Set your BorderBrush when the mouse is over
</Trigger>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" Value="{StaticResource ButtonBackgroundDisabled}"/> //Set your background when the button is disabled
<Setter Property="BorderBrush" Value="{StaticResource ButtonBorderBrushDisabled}" /> //Set your BorderBrush when the button is disabled
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Button.Resources>
