在wpf的wb:InputVerifyWodowBase范围内修改title背景颜色

您可以使用以下代码在InputVerifyWodowBase中修改标题栏的背景颜色：

<Style TargetType="{x:Type local:InputVerifyWodowBase}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:InputVerifyWodowBase}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                    <Grid>
                        <Grid.RowDefinitions>
                            <RowDefinition Height="Auto"/>
                            <RowDefinition Height="*"/>
                        </Grid.RowDefinitions>
                        <Border x:Name="PART_TitleBar"
                                Grid.Row="0"
                                Background="Red" <!-- 修改此处的颜色 -->
                                Height="32"
                                BorderThickness="0,0,0,1"
                                BorderBrush="{StaticResource WindowBorderBrush}">
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="Auto"/>
                                    <ColumnDefinition Width="*"/>
                                    <ColumnDefinition Width="Auto"/>
                                </Grid.ColumnDefinitions>
                                <Image x:Name="PART_Icon"
                                       Grid.Column="0"
                                       Source="{TemplateBinding Icon}"
                                       Margin="2"/>
                                <TextBlock x:Name="PART_Title"
                                           Grid.Column="1"
                                           Text="{TemplateBinding Title}"
                                           VerticalAlignment="Center"
                                           Margin="2"/>
                                <Button x:Name="PART_CloseButton"
                                        Grid.Column="2"
                                        Style="{StaticResource WindowCloseButtonStyle}"
                                        Command="{Binding CloseCommand, RelativeSource={RelativeSource TemplatedParent}}"
                                        ToolTip="Close"/>
                            </Grid>
                        </Border>
                        <ContentPresenter x:Name="PART_ContentPresenter" 
                                          Grid.Row="1" 
                                          Content="{TemplateBinding Content}" 
                                          ContentTemplate="{TemplateBinding ContentTemplate}" />
                    </Grid>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

在上面的代码中，找到名为“PART_TitleBar”的Border元素，并将其背景颜色更改为所需的颜色即可。
