写样式文件，或者直接在app中加载

//样式文件
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <materialDesign:BundledTheme
                BaseTheme="Dark"
                PrimaryColor="DeepPurple"
                SecondaryColor="Lime" />
             //地址加载（可以多个）
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
        </ResourceDictionary.MergedDictionaries>
        //直接写样式
        <Style x:Key="MyListBoxItemStyle" TargetType="ListBoxItem">
            <Setter Property="MinHeight" Value="40" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type ListBoxItem}">
                        <Grid>
                            <Border x:Name="borderHeader" />
                            <Border x:Name="border" />
                            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
                        </Grid>

                        <ControlTemplate.Triggers>
                            <Trigger Property="IsSelected" Value="True">
                                <Setter TargetName="borderHeader" Property="BorderThickness" Value="4,0,0,0" />
                                <Setter TargetName="borderHeader" Property="BorderBrush" Value="{DynamicResource PrimaryHueLightBrush}" />
                                <Setter TargetName="border" Property="Background" Value="{DynamicResource PrimaryHueLightBrush}" />
                                <Setter TargetName="border" Property="Opacity" Value="0.2" />
                            </Trigger>

                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter TargetName="border" Property="Background" Value="{DynamicResource PrimaryHueLightBrush}" />
                                <Setter TargetName="border" Property="Opacity" Value="0.2" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
        
    </ResourceDictionary>
</Application.Resources>

样式的重点

ContentPresenter：动态绑定内容（<ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />）

RelativeSource：找数据来源（<MouseBinding MouseAction="LeftClick"

Command="{Binding DataContext.NavigateCommand, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType=ItemsControl}}"
CommandParameter="{Binding}"/>）

 CommandParameter：传递参数（{Binding ElementName=todoList,Path=SelectedItem}）

Converter：参数值转换（ IsChecked="{Binding Status,Converter={StaticResource intToBool}}"）
