Question

每次，我都会添加WPF按钮，边框内部会出现白色薄边框，我该如何删除？

这是XAMl for button

  <Button BorderThickness="1" Content="Calculate" Height="25" 
        Foreground="Black" Background="#FF35C57D" 
        BorderBrush="#FF28B363" OpacityMask="#FF35C57D" />

更新我正在添加混合模板副本以供参考，其薄边框位于常规边框内。

<Window.Resources>
    <Style x:Key="ButtonFocusVisual">
        <Setter Property="Control.Template">
            <Setter.Value>
                <ControlTemplate>
                    <Rectangle Margin="2" SnapsToDevicePixels="true"   
                    Stroke="{DynamicResource {x:Static  
                        SystemColors.ControlTextBrushKey}}"  
                          StrokeThickness="1" StrokeDashArray="1 2"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

    <LinearGradientBrush x:Key="ButtonNormalBackground" EndPoint="0,1" StartPoint="0,0">

                <ControlTemplate TargetType="{x:Type Button}">

                    </Themes:ButtonChrome>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsKeyboardFocused" Value="true">
                            <Setter Property="RenderDefaulted" TargetName="Chrome" Value="true"/>
                        </Trigger>
                        <Trigger Property="ToggleButton.IsChecked" Value="true">
                            <Setter Property="RenderPressed" TargetName="Chrome" Value="true"/>
                        </Trigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Foreground" Value="#ADADAD"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>

像以下代码一样安排Button Template代码Border作为ContentPresenter的父母，并从代码中移除Themes:ButtonChrome。）

<Style x:Key="NoChromeButton" TargetType="{x:Type Button}">
    ..... OTHER CODES ....
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Button}">
                <Border BorderBrush="Green" BorderThickness="1" CornerRadius="7" Background="{TemplateBinding Background}" >
                    <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    ..... OTHER CODES ....
</Style>

请从WPF按钮中删除常规边框内的白色细边框
