我需要更改TabControl标题的背景颜色,但TabControl没有它的属性,我该怎么做.请帮帮我.这是我的代码:

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="502" Width="628">
    <TabControl Background="#123" TabStripPlacement="Left" HorizontalAlignment="Stretch" BorderBrush="#41020202">
        <TabControl.BitmapEffect>
            <DropShadowBitmapEffect Color="Black" Direction="270"/>
        </TabControl.BitmapEffect>
        <TabControl.Resources>
            <Style TargetType="{x:Type TabItem}">
                <Setter Property="BorderThickness" Value="0"/>
                <Setter Property="Padding" Value="0" />
                <Setter Property="HeaderTemplate">
                    <Setter.Value>
                        <DataTemplate>
                            <Border x:Name="grid" Background="Red">
                                <ContentPresenter>
                                    <ContentPresenter.Content>
                                        <TextBlock Margin="4" FontSize="15" Text="{TemplateBinding Content}"/>
                                    </ContentPresenter.Content>
                                    <ContentPresenter.LayoutTransform>
                                        <RotateTransform Angle="270" />
                                    </ContentPresenter.LayoutTransform>
                                </ContentPresenter>
                            </Border>
                            <DataTemplate.Triggers>
                                <DataTrigger Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type TabItem}},Path=IsSelected}" Value="True">
                                    <Setter TargetName="grid" Property="Background" Value="Green"/>
                                </DataTrigger>
                            </DataTemplate.Triggers>
                        </DataTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </TabControl.Resources>
        <TabItem Header="Tab Item 1" />
        <TabItem Header="Tab Item 2" />
        <TabItem …

有两个流,第一个显示进程表,第二个流则考虑计数和显示.最初是为第一个推出,然后是第二个:

Thread t1 = new Thread(tmh1.FillTable);
Thread t2 = new Thread(tmh1.GetGeneralInfo);
t1.Start();
t2.Start();

以下是在线程中运行的方法:

public void FillTable()
{
    while (true)
    {
         lock (lockObj)
         {
            arr.Clear();
            arr.AddRange(Process.GetProcesses());
            TableFormatter.Line();
            TableFormatter.Row("Name", "ID", "threads quantity", "Start time");
            TableFormatter.Line();
          }
          Thread.Sleep(interval);
      }
}
public void GetGeneralInfo()
{
    while (true)
    {
        lock (lockObj)
        {
           Console.WriteLine(arr.Count.ToString());
        }
    Thread.Sleep(interval);
    }
}

结果:

0
-----------------------------------------------------------------------------
|     Name     |         ID       |  threads quantity|  Start time          |
-----------------------------------------------------------------------------

但应该如下:

-----------------------------------------------------------------------------
|     Name     |         ID       |  threads quantity|  Start time          |
----------------------------------------------------------------------------- …
