WPF后台动态添加TabItem并设置样式

1、前台myWindow.xaml文件中的代码
            <TabControl x:Name="menuTab" Grid.RowSpan="2" Margin="0" Style="{DynamicResource TabControlStyle}" Grid.Row="1" Background="{x:Null}">
                <TabItem Header="系统设置" Height="83" Margin="80,0,0,0" Width="74" Style="{DynamicResource TabItemStyle}">
                    <TabItem.Background>
                        <ImageBrush ImageSource="skin/ico/ico_dsmain.png"/>  <!--这里图片需要替换才能正常运行-->
                    </TabItem.Background>
                    <Grid Background="{DynamicResource MyBrush}"/>
                </TabItem>

                 <!--这里在后台动态添加和上面系统设置类似的TabItem和对应的样式等属性-->

         </TabControl>

2、后台myWindow.xaml.cs文件中的代码
private void Button_Click(object sender, RoutedEventArgs e)
 {
            //动态添加子菜单
            TabItem myDnymicTab = new TabItem() { Header = "用户管理", Height = 83, Width = 74 };
            //设置图片
            ImageBrush myImageBrush=new ImageBrush(new BitmapImage(new Uri(@"../../skin/ico/ico_PluginCleaner.png", UriKind.Relative)));
            myDnymicTab.Background=myImageBrush;
            //设置位置
            Thickness myThickness =new Thickness(120,0,0,0);
            myDnymicTab.Margin=myThickness;
            //设置样式
            Style myStyle = (Style)this.FindResource("TabItemStyle");//TabItemStyle 这个样式是引用的资源文件中的样式名称
            myDnymicTab.Style = myStyle;
            //添加TabItem到TabControl中
            menuTab.Items.Add(myDnymicTab);
            menuTab.SelectedItem = myDnymicTab;

}

3、App.xaml中添加样式字典文件引用
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <!--App.xaml资源样式-->
            <ResourceDictionary Source="TabControlStyle.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

4、资源文件TabControlStyle.xaml中的样式：

<!-- 应该在此定义资源字典条目。-->
 <Style x:Key="TabControlStyle" TargetType="{x:Type TabControl}">
  <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
  <Setter Property="Padding" Value="4,4,4,4"/>

      </Border>
      <StackPanel x:Name="HeaderPanel" Margin="0" IsItemsHost="True">
