类库中的可移植 XAML 样式

Question

所以我有一个应用程序，其样式直接放入 App.xaml 文件中，如下所示：

<Application x:Class="Test.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             Startup="OnStartup">
    <Application.Resources>
        <Style x:Key="SpecialButtonStyle" TargetType="Button">
            <Setter Property="Content" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" />
            <Setter Property="OverridesDefaultStyle" Value="true"/>
            <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background}" />
            <Setter Property="BorderThickness" Value="2" />
            <Setter Property="BorderBrush" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background}" />
            <Setter Property="Foreground" Value="White" />
            <Setter Property="Block.Foreground" Value="White" />
            <Setter Property="TextBlock.Foreground" Value="White" />
            <Setter Property="TextElement.Foreground" Value="White" />
            <Setter Property="FontWeight" Value="Bold" />
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="False">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type Button}">
                                <Border Background="{TemplateBinding Background}" Padding="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=BorderThickness}">
                                    <Border Background="{TemplateBinding BorderBrush}">
                                        <ContentControl Foreground="White">
                                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                        </ContentControl>
                                    </Border>
                                </Border>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Trigger>
            </Style.Triggers>
        </Style>
    </Application.Resources>
</Application>

我想将其作为样式包含在我的类库中，以便引用该库的任何 xaml 项目都可以将“SpecialButtonStyle”视为设计器中的可选“样式”。我已经阅读了几篇有关 ResourceDictionaries 和创建可移植 XAML 控件的文章，但我仍然感到困惑。我基本上希望将样式集合作为类库的一部分包含在内。

任何帮助将不胜感激。谢谢！

您读到的内容是正确的。

ResourceDictionary您需要在共享程序集中创建一个具有给定名称的普通文件。

App.xaml然后，您可以将其包含在您的应用程序中ResourceDictionary，MergedDictionary因此您的整个应用程序将可以访问所有共享词典资源。

脚步：

1. 创建另一个项目 WPF Control Library Project（与用户或自定义无关）
2. 在新项目中右键->添加->ResourceDictionary
3. 粘贴您的样式，使其如下所示：

Dictionary1.xaml

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="SpecialButtonStyle" TargetType="Button">
        <Setter Property="Content" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Content}" />
        <Setter Property="OverridesDefaultStyle" Value="true"/>
        <Setter Property="Background" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background}" />
        <Setter Property="BorderThickness" Value="2" />
        <Setter Property="BorderBrush" Value="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Background}" />
        <Setter Property="Foreground" Value="White" />
        <Setter Property="Block.Foreground" Value="White" />
        <Setter Property="TextBlock.Foreground" Value="White" />
        <Setter Property="TextElement.Foreground" Value="White" />
        <Setter Property="FontWeight" Value="Bold" />
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="False">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type Button}">
                            <Border Background="{TemplateBinding Background}" Padding="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=BorderThickness}">
                                <Border Background="{TemplateBinding BorderBrush}">
                                    <ContentControl Foreground="White">
                                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                                    </ContentControl>
                                </Border>
                            </Border>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Trigger>
        </Style.Triggers>
    </Style>
</ResourceDictionary>

4. 在您的主项目中引用这个新的控制库
5. App.xaml参考中Dictionary1.xaml

App.xaml

<Application x:Class="WpfApplication1.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
                 StartupUri="NestedXamlObjects.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/WpfControlLibrary1;component/Dictionary1.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>
