我在 Brushes.xaml 中有这个:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:controls="clr-namespace:SkinBox.Controls">
    <SolidColorBrush x:Key="{x:Static controls:Keys.BackgroundBrushKey}"
                     Color="{DynamicResource {x:Static controls:Keys.BackgroundColorKey}}" />
</ResourceDictionary>

并在 Generic.xaml 中像这样使用它:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:local="clr-namespace:SkinBox.Controls"
                    xmlns:system="clr-namespace:System;assembly=System">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/SkinBox.Controls;component/Themes/Skins/Blue.xaml" />
        <ResourceDictionary Source="pack://application:,,,/SkinBox.Controls;component/Themes/Brushes.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

问题是 wpf 冻结了画笔,所以DynamicResource没有效果。

有没有一种干净的方法来解决这个问题?我只能想到讨厌的黑客。

想到一个解决方法:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:controls="clr-namespace:SkinBox.Controls">
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="pack://application:,,,/SkinBox.Controls;component/Themes/Skins/Yellow.Colors.xaml" />
        <ResourceDictionary Source="pack://application:,,,/SkinBox.Controls;component/Themes/Brushes.xaml" />
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

这仍然不能提供真正的动态资源,但它会重新应用画笔,以便它们在应用皮肤时更新。

无需在每个皮肤上复制刷子。
