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"/>
