我正在使用这个xaml代码覆盖应用程序中复选框的背景色。

<Style TargetType="{x:Type CheckBox}"              
        BasedOn="{StaticResource CheckBoxStyle}">
        <Setter Property="Background"
                Value="Orange" />           
        <Setter Property="Foreground"
                Value="Yellow" />
        <Setter Property="FontSize"
                Value="30" />
  </Style>

在CheckBoxStyle中，有一个复选框的控件模板，复选框的背景色是蓝色。我需要用橙子覆盖它。但是上面的代码不起作用。有人能建议我解决这个问题吗？

它是蓝色的原因是因为在CheckBox默认模板中有一个名为“IsMouseOver”的触发器，每次您将鼠标悬停在CheckBox上时，它都会将其更改为蓝色，您将需要更改默认的CheckBox模板。
步骤1：右键单击复选框并选择“编辑模板\编辑副本...”

第二步：命名你的新风格。

步骤3：在ControlTemplate下，触发器查找IsMouseOver触发器并将其值设置为橙子。
