您需要修改ControlTemplate。在Visual Studio中右键单击设计模式中的TextBox，然后选择Edit Template - ＆gt; Edit a Copy将默认模板复制到XAML标记中，然后根据您的要求进行编辑： / p>

<TextBox>
    <TextBox.Style>
        <Style TargetType="{x:Type TextBox}">
            <Setter Property="Foreground" Value="#FFF0E6D2"/>
            <Setter Property="FontSize" Value="15" />
            <Setter Property="BorderBrush" Value="#FF785A28"/>
            <Setter Property="VerticalContentAlignment" Value="Center"/>
            <Setter Property="Background" Value="#FF000306"/>
            <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
            <Setter Property="BorderThickness" Value="1"/>
            <Setter Property="KeyboardNavigation.TabNavigation" Value="None"/>
            <Setter Property="HorizontalContentAlignment" Value="Left"/>
            <Setter Property="FocusVisualStyle" Value="{x:Null}"/>

            <Setter Property="ScrollViewer.PanningMode" Value="VerticalFirst"/>
            <Setter Property="Stylus.IsFlicksEnabled" Value="False"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type TextBox}">

除非您编辑控件的模板，否则您可以更改的内容非常有限。这是WPF TextBox的默认模板，因此请将其更改为符合您所需的样式：https://docs.microsoft.com/en-us/dotnet/framework/wpf/controls/textbox-styles-and-templates

覆盖xaml ui元素的默认Windows 10样式
