C# 使用WPF为多个动态蒙皮词典创建别名颜色定义

我正在尝试在一个大型WPF应用程序中设置一个主题框架。目前，我们找到的解决方案是为每个调色板创建单独的.xaml文件，如下所示：

<LightColors.xaml>
<Color x:Key="MainPanelColor">Aqua</Color>
<Color x:Key="MainItemColor">Orange</Color>
<SolidColorBrush x:Key="MainPanelBrush" Color="{StaticResource MainPanelColor}" />
<SolidColorBrush x:Key="MainItemBrush"  Color="{StaticResource MainItemColor}" />

水绿色
橙色

然后，UI引用这些项目，如下所示：

<Textblock Foreground="{DynamicResource MainItemBrush}"/>

在运行期间，在C#中更改调色板。这个主题框架完成了允许在运行时更改主题的任务

问题：我想在UI和颜色之间创建一个层，以便调色板颜色可以链接到整个UI中使用的大量颜色定义列表。我发现的唯一解决方案是在works附近添加如下文件：

<ColorDefinitions.xaml>
<DynamicResource x:Key="Textblock_SetupPage_Foreground" ResourceKey="MainItemBrush" />
<DynamicResource x:Key="SecondDefinition" ResourceKey="MainItemBrush" />

<Textblock Foreground="{StaticResource Textblock_SetupPage_Foreground}" />

private void RadioButton_Checked(object sender, RoutedEventArgs e)
    {
        string skinName = "LightSkin";

        if (((RadioButton)sender).Name == "DarkSkin")
        {
            skinName = "DarkSkin";
        }

        ResourceDictionary resources = new ResourceDictionary();
        resources.Source = new Uri($"pack://application:,,,/MySkinsLibrary;component/Skins/{skinName}.xaml");
        Application.Current.Resources = resources;
    }

并在UI中引用此新资源，如下所示：

<ColorDefinitions.xaml>
<DynamicResource x:Key="Textblock_SetupPage_Foreground" ResourceKey="MainItemBrush" />
<DynamicResource x:Key="SecondDefinition" ResourceKey="MainItemBrush" />

<Textblock Foreground="{StaticResource Textblock_SetupPage_Foreground}" />

private void RadioButton_Checked(object sender, RoutedEventArgs e)
    {
        string skinName = "LightSkin";

        if (((RadioButton)sender).Name == "DarkSkin")
        {
            skinName = "DarkSkin";
        }

        ResourceDictionary resources = new ResourceDictionary();
        resources.Source = new Uri($"pack://application:,,,/MySkinsLibrary;component/Skins/{skinName}.xaml");
        Application.Current.Resources = resources;
    }

不过，这个解决方案并不完全有效。它只允许单个UI元素使用一个动态资源，如“Textblock\u SetupPage\u Foreground”，将Textblock引用更改为DynamicSource会产生错误。如何完成此任务？

不太确定这是否解决了您的问题，但我可以向您展示如何在LOB中实现蒙皮。示例解决方案由两个程序集和示例应用程序组成

MyCustomControlLibrary定义了颜色和笔刷以及一个示例自定义控件。颜色和画笔可以进一步分离成一个额外的组件

MySkinsLibrary定义皮肤并使用MyControlLibrary中的定义（资源）

WpfSkinTestApp使用皮肤，并间接使用MyCStumControl库

Colors.xaml：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:local="clr-namespace:MyCustomControlLibrary">
<Color x:Key="MyDarkColor">#FF123456</Color>
<Color x:Key="MyLightColor">#FF456789</Color>
<Color x:Key="MyNeutralColor">#FF666666</Color>

对于完整性，这是测试应用程序的主窗口：

<Window x:Class="WpfSkinTestApp.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:customControls="clr-namespace:MyCustomControlLibrary;assembly=MyCustomControlLibrary"
    xmlns:local="clr-namespace:WpfSkinTestApp"
    mc:Ignorable="d"
    Title="MainWindow" Height="350" Width="525"
    Background="{StaticResource MyNeutralColorBrush}">
<Grid>
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition/>
        <ColumnDefinition/>
    </Grid.ColumnDefinitions>
    <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition Height="Auto"/>
        <RowDefinition/>
        <RowDefinition/>
    </Grid.RowDefinitions>
    <TextBlock Grid.Column="1"
               Grid.Row="1"
               Text="Example Colors"
               Style="{DynamicResource MyTextBlockStyle}"/>
    <customControls:MyCustomControl Grid.Column="1"
                                    Grid.Row="2"
                                    Style="{DynamicResource MyCustomControlStyle}"/>
    <StackPanel Grid.Column="2"
                Grid.Row="2"
                Margin="24"                    >
        <RadioButton x:Name="LightSkin" GroupName="1" Content="Light Skin" IsChecked="True" Checked="RadioButton_Checked"/>
        <RadioButton x:Name="DarkSkin" GroupName="1" Content="Dark Skin" Checked="RadioButton_Checked"/>
    </StackPanel>
</Grid>

如果这是您想要的，请告诉我。

感谢您为这个答案所付出的努力。您的解决方案与我最终使用的类似：在每个skin resourcedictionary中重新定义资源。我为颜色和画笔重新定义了Button_Base_BorderDisabled等资源，您也重新定义了MyTextBlockStyle等样式。我希望的仍然存在。。。将颜色链接到一个别名中。例如，为MyDarkColor、MyLightColor和MyNeutralColor（如MainColor）创建别名，并在整个UI中仅使用MainColor引用，但使其可以动态更改。

private void RadioButton_Checked(object sender, RoutedEventArgs e)
    {
        string skinName = "LightSkin";

        if (((RadioButton)sender).Name == "DarkSkin")
        {
            skinName = "DarkSkin";
        }

        ResourceDictionary resources = new ResourceDictionary();
        resources.Source = new Uri($"pack://application:,,,/MySkinsLibrary;component/Skins/{skinName}.xaml");
        Application.Current.Resources = resources;
    }
