我想从dependencyproperty更改TextBlock的前景色.
但我不改变文本块颜色.
我的代码中不知道这个问题.
如何使用触发器更改TextBlock的前景色？

XAML:

<TextBlock Name="TestBlock" Text="Test color" >
    <TextBlock.Style>
        <Style TargetType="TextBlock">
            <Style.Triggers>
                <Trigger Property ="IsMouseOver" Value="True">
                    <Setter Property= "Foreground" Value="Gray"/>
                </Trigger>
                <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="0">
                    <Setter Property="Foreground" Value="Red" />
                </DataTrigger>
                <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="1">
                    <Setter Property="Foreground" Value="Blue" />
                </DataTrigger>
                <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="2">
                    <Setter Property="Foreground" Value="Green" />
                </DataTrigger>
                <DataTrigger Binding="{Binding Path=TestColorMode2, RelativeSource={RelativeSource AncestorType={x:Type local:Window1}}}" Value="3">
                    <Setter Property="Foreground" Value="Black" />
                </DataTrigger>
            </Style.Triggers>
        </Style>
    </TextBlock.Style>
</TextBlock>

码:

public static DependencyProperty TestColorModeProperty …
