In WPF you can modify or recreate the look and feel of controls. So if your example what they have done is they changed the appearance of the TextBox by modifying the ControlTemplateof the existing TextBox. So to see and explore the piece of code just use the below code
在 WPF 中，您可以修改或重新创建控件的外观和感觉。因此，如果您的示例他们所做的是通过修改ControlTemplate现有TextBox. 所以要查看和探索这段代码，只需使用下面的代码
<Window x:Class="WpfApplication4.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="300" Width="300">
<Window.Resources>
<ControlTemplate x:Key="TextBoxBaseControlTemplate" TargetType="{x:Type TextBoxBase}">
<Border Background="{TemplateBinding Background}"
x:Name="Bd" BorderBrush="Black"
BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="10">
<ScrollViewer x:Name="PART_ContentHost"/>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" TargetName="Bd"/>
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}"/>
</Trigger>
<Trigger Property="Width" Value="Auto">
<Setter Property="MinWidth" Value="100"/>
</Trigger>
<Trigger Property="Height" Value="Auto">
<Setter Property="MinHeight" Value="20"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Window.Resources>
<Grid>
<TextBox Template="{StaticResource TextBoxBaseControlTemplate}" Height="25" Margin="5"></TextBox>
</Grid>
So we have declared a static resource in the Resource section of the Window and we have used the Resource TextBoxBaseControlTemplate in the Templateproperty of the TextBoxas Template="{StaticResource TextBoxBaseControlTemplate}".
因此，我们宣布在窗口的资源部分的静态资源，我们已经在使用的资源TextBoxBaseControlTemplateTemplate的财产TextBox作为 Template="{StaticResource TextBoxBaseControlTemplate}"。

@Smolla had a much better answer in his comment on @Daniel Casserly's answer:
@Smolla 在对@Daniel Casserly 的回答的评论中给出了更好的答案：
<TextBox Text="TextBox with CornerRadius">
<TextBox.Resources>
<Style TargetType="{x:Type Border}">
<Setter Property="CornerRadius" Value="3"/>
</Style>
</TextBox.Resources>
</TextBox>
If you want all the borders of TextBoxes and ListBoxes to have rounded corners, put the style into your Window's or App's <Resources>.
如果您希望 TextBox 和 ListBox 的所有边框都具有圆角，请将样式放入 Window 或 App 的<Resources>.

You can change all textboxes to have rounded corners by using the following style:
您可以使用以下样式将所有文本框更改为圆角：
<Style TargetType="{x:Type TextBox}">
<Style.Resources>
<Style TargetType="{x:Type Border}">
<Setter Property="CornerRadius" Value="3" />
</Style>
</Style.Resources>
</Style>

Try the solutions there, they are in quite a lot of detail and certainly enough detail for you to know where to put the code.
尝试那里的解决方案，它们非常详细，当然足够详细，让您知道将代码放在哪里。

Just set BorderThicknessof textbox to zero add a border around textbox.
只需将 BorderThicknessof 文本框设置为零即可在文本框周围添加边框。
<Border BorderThickness="1" BorderBrush="Black" CornerRadius="10" Padding="2"
HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBox Text="Hello ! " BorderThickness="0"/>
</Border>
Output is as shown in image!
输出如图所示！

You can use attached properties for setting TextBoxborder radius (also the same will work for buttons).
您可以使用附加属性来设置TextBox边框半径（同样适用于按钮）。
Create class for attached property
为附加属性创建类
public class CornerRadiusSetter
{
public static CornerRadius GetCornerRadius(DependencyObject obj) => (CornerRadius)obj.GetValue(CornerRadiusProperty);
public static void SetCornerRadius(DependencyObject obj, CornerRadius value) => obj.SetValue(CornerRadiusProperty, value);
public static readonly DependencyProperty CornerRadiusProperty =
DependencyProperty.RegisterAttached(nameof(Border.CornerRadius), typeof(CornerRadius),
typeof(CornerRadiusSetter), new UIPropertyMetadata(new CornerRadius(), CornerRadiusChangedCallback));
public static void CornerRadiusChangedCallback(object sender, DependencyPropertyChangedEventArgs e)
{
Control control = sender as Control;
if (control == null) return;
control.Loaded -= Control_Loaded;
control.Loaded += Control_Loaded;
}
private static void Control_Loaded(object sender, EventArgs e)
{
Control control = sender as Control;
if (control == null || control.Template == null) return;
control.ApplyTemplate();
Border border = control.Template.FindName("border", control) as Border;
if (border == null) return;
border.CornerRadius = GetCornerRadius(control);
}
}
Then you can use attached property syntax to style multiple textboxes without style duplicates:
然后，您可以使用附加属性语法来设置多个文本框的样式，而不会出现样式重复：
<TextBox local:CornerRadiusSetter.CornerRadius="10" />
<TextBox local:CornerRadiusSetter.CornerRadius="5, 0, 0, 5" />
<TextBox local:CornerRadiusSetter.CornerRadius="10, 4, 18, 7" />
