WPF圆角复选框：如何为后台生成的CheckBox绑定自定义ControlTemplate

已成功创建带圆角样式的CheckBox自定义ControlTemplate，但无法将该模板应用于后台代码生成的CheckBox，求实现两者绑定的方法。

现有自定义ControlTemplate（XAML） #

<Window.Resources>
        <Style x:Key="OptionMarkFocusVisual">
            <Setter Property="Control.Template">
                <Setter.Value>
                    <ControlTemplate>
                        <Rectangle Margin="14,0,0,0" StrokeDashArray="1 2" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" SnapsToDevicePixels="true" StrokeThickness="1"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
        <SolidColorBrush x:Key="OptionMark.Static.Glyph" Color="#FF212121"/>

现有后台生成CheckBox代码（C#） #

private void GenerateCheckbox()
{
    CheckBox checkBoxTest = new CheckBox();
    checkBoxTest.Content = "Test";
    grid.Children.Add(checkBoxTest);
}

有两种简单方式可将自定义ControlTemplate应用到后台生成的CheckBox：

方式一：直接赋值ControlTemplate #

通过FindResource从Window资源中获取定义好的模板，直接赋值给CheckBox的Template属性：

private void GenerateCheckbox()
{
    CheckBox checkBoxTest = new CheckBox();
    checkBoxTest.Content = "Test";
    // 获取并应用自定义ControlTemplate
    checkBoxTest.Template = (ControlTemplate)this.FindResource("CheckBoxTemplate1");
    grid.Children.Add(checkBoxTest);
}

方式二：通过Style绑定（更灵活） #

若需扩展样式的其他属性，建议先在XAML中定义引用该模板的Style，再在后台应用：

步骤1：在Window.Resources中添加Style #

<Style x:Key="RoundedCheckBoxStyle" TargetType="CheckBox">
    <Setter Property="Template" Value="{StaticResource CheckBoxTemplate1}"/>
    <!-- 可添加其他样式设置，比如边距、字体大小等 -->
    <Setter Property="Margin" Value="5"/>
</Style>

步骤2：后台代码中应用Style #

private void GenerateCheckbox()
{
    CheckBox checkBoxTest = new CheckBox();
    checkBoxTest.Content = "Test";
    // 获取并应用自定义Style
    checkBoxTest.Style = (Style)this.FindResource("RoundedCheckBoxStyle");
    grid.Children.Add(checkBoxTest);
}
