The way to do this is to use a control template to draw the border yourself. You can do this in many different ways, heres a couple for you to look at.
这样做的方法是使用控件模板自己绘制边框。您可以通过多种不同的方式来做到这一点，这里有一些供您查看。
The quick hack approach:
快速破解方法：
<TextBox>
<TextBox.Template>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Rectangle Stroke="{StaticResource ResourceKey=detailMarkBrush}" StrokeThickness="1"/>
<TextBox Margin="1" Text="{TemplateBinding Text}" BorderThickness="0"/>
</Grid>
</ControlTemplate>
</TextBox.Template>
</TextBox>
and then theres using resources...
然后是使用资源...
<ResourceDictionary>
<Color x:Key="detailMark">#FFA1A9B3</Color>
<SolidColorBrush x:Key="detailMarkBrush" Color="{StaticResource ResourceKey=detailMark}" />
<Style x:Key="flatTextBox" TargetType="{x:Type TextBox}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBox}">
<Grid>
<Rectangle Stroke="{StaticResource ResourceKey=detailMarkBrush}" StrokeThickness="1"/>
<TextBox Margin="1" Text="{TemplateBinding Text}" BorderThickness="0"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
and then you can use the style:
然后你可以使用样式：
<TextBox Style="{StaticResource ResourceKey=flatTextBox}" />

This is better way to me, make a custom template with border, to override the default one.
这对我来说是更好的方法，制作带有边框的自定义模板，以覆盖默认模板。
And most important make ScrollViewernamed PART_ContentHost, to fit inner TemplatePart, and for any other features work like default.
最重要的是 make ScrollViewernamed PART_ContentHost，适合内部TemplatePart，以及任何其他功能都像默认一样工作。
simular to example from MSDN:
类似于MSDN 中的示例：
<Style TargetType="TextBox">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TextBoxBase}">
<Border CornerRadius="2" Padding="2" Background="#19212F" BorderBrush="Red" BorderThickness="1">
<ScrollViewer Margin="0" x:Name="PART_ContentHost" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
