您可以将每个调色板颜色用作颜色 (PaletteColorThemeKey) 或画笔 (PaletteBrushThemeKey)。

MainWindow.xaml

?

class="prettyprint lang-xml"><ThemedWindow ...
xmlns:dxi="http://schemas.devexpress.com/winfx/2008/xaml/core/internal"
xmlns:dxt="http://schemas.devexpress.com/winfx/2008/xaml/themes">
<Button Background="{dxi:ThemeResource {dxt:PaletteBrushThemeKey ResourceKey=Button.Background}}"
BorderBrush="{dxi:ThemeResource {dxt:PaletteBrushThemeKey ResourceKey=Border}}"
BorderThickness="1" />
</ThemedWindow>

?

示例

下面的代码示例演示了如何将VS2017Blue主题的Border调色板资源绑定到自定义控件的BorderBrush属性：

CustomControls.cs

?

using System.Windows;
using System.Windows.Controls;

namespace WpfApp36 {
public class CustomControl1 : Control {
static CustomControl1() {
DefaultStyleKeyProperty.OverrideMetadata(typeof(CustomControl1), new FrameworkPropertyMetadata(typeof(CustomControl1)));
}

public string Text {
get { return (string)GetValue(TextProperty); }
set { SetValue(TextProperty, value); }
}
public static readonly DependencyProperty TextProperty =
DependencyProperty.Register("Text", typeof(string), typeof(CustomControl1), new PropertyMetadata(null));
}
}

?

MainWindow.xaml

?

<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:local="clr-namespace:WpfApp36"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="WpfApp36.MainWindow">
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
</Grid.RowDefinitions>
<local:CustomControl1 Grid.Row="0" Margin="5" Text="Custom control binding to a theme name"/>
</Grid>
</Window>

CustomControl1_Resources.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:dxt="http://schemas.devexpress.com/winfx/2008/xaml/core/themekeys"
xmlns:local="clr-namespace:WpfApp36">
<Style TargetType="{x:Type local:CustomControl1}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:CustomControl1}">
<Border BorderBrush="{DynamicResource {dxt:PaletteBrushThemeKey ResourceKey=Border, ThemeName=VS2017Blue}}" BorderThickness="3">
<TextBlock Foreground="Black" HorizontalAlignment="Center" Text="{TemplateBinding Text}" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>

App.xaml

<Application x:Class="WpfApp36.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
StartupUri="MainWindow.xaml">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/WPFApp36;component/CustomControl1_Resources.xaml" />
</ResourceDictionary.MergedDictionaries>
