WPF中使用checkbox控件制作bool类型开关的代码教程

代码如下：

<Window x:Class="WpfApplication1.Window1"

        xmlns:x="https://schemas.microsoft.com/winfx/2006/xaml"
        x:Name="Window"
        Title="Window1"
        Width="320" 
        Height="240" >

    <Window.Resources>
        <Style x:Key="CheckBoxStyle1" TargetType="{x:Type CheckBox}">

            <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}"/>
            <Setter Property="Template">
                <Setter.Value>
