Question

我想在WPF（XAML）中创建一个边框，它使用当前Windows主题（XP，Areo，Classic，Modern UI）中的颜色。

我已尝试使用SystemColors类中的一些画笔，但边框与TextBox的默认边框看起来不一样。

有没有办法获得真正的边界画笔？

以下是WPF用于TextBox控件的默认样式：

  <Style TargetType="{x:Type TextBox}">
    <Setter Property="SnapsToDevicePixels"
            Value="True" />
    <Setter Property="OverridesDefaultStyle"
            Value="True" />
    <Setter Property="KeyboardNavigation.TabNavigation"
            Value="None" />
    <Setter Property="FocusVisualStyle"
            Value="{x:Null}" />
    <Setter Property="MinWidth"
            Value="120" />
    <Setter Property="MinHeight"
            Value="20" />
    <Setter Property="AllowDrop"
            Value="true" />
    <Setter Property="Template">
      <Setter.Value>
        <ControlTemplate TargetType="{x:Type TextBoxBase}">
          <Border Name="Border"
                  CornerRadius="2"
                  Padding="2"
                  BorderThickness="1">
            <Border.Background>
              <SolidColorBrush Color="{DynamicResource ControlLightColor}" />
            </Border.Background>
            <Border.BorderBrush>
              <SolidColorBrush Color="{DynamicResource BorderMediumColor}" />
            </Border.BorderBrush>
            <VisualStateManager.VisualStateGroups>
              <VisualStateGroup x:Name="CommonStates">
                <VisualState x:Name="Normal" />
                <VisualState x:Name="Disabled">
                  <Storyboard>
                    <ColorAnimationUsingKeyFrames Storyboard.TargetName="Border"
                                                  Storyboard.TargetProperty="(Panel.Background).
                      (SolidColorBrush.Color)">
                      <EasingColorKeyFrame KeyTime="0"
                                           Value="{StaticResource DisabledControlLightColor}" />
                    </ColorAnimationUsingKeyFrames>
                  </Storyboard>
                </VisualState>
                <VisualState x:Name="ReadOnly">
                  <Storyboard>
                    <ColorAnimationUsingKeyFrames Storyboard.TargetName="Border"
                                                  Storyboard.TargetProperty="(Panel.Background).
                      (SolidColorBrush.Color)">
                      <EasingColorKeyFrame KeyTime="0"
                                           Value="{StaticResource DisabledControlDarkColor}" />
                    </ColorAnimationUsingKeyFrames>
                  </Storyboard>
                </VisualState>
                <VisualState x:Name="MouseOver" />
              </VisualStateGroup>
            </VisualStateManager.VisualStateGroups>
            <ScrollViewer Margin="0"
                          x:Name="PART_ContentHost" />
          </Border>
        </ControlTemplate>
      </Setter.Value>
    </Setter>
  </Style>
