Class 库中的便携式 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：

<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>

我想将其作为一种样式包含在我的 class 库中，以便任何引用该库的 xaml 项目都可以将 "SpecialButtonStyle" 视为可选 "Style"在设计器中。我已经阅读了几篇关于 ResourceDictionaries 和创建可移植 XAML 控件的文章，但我仍然感到困惑。我基本上想要一组样式作为 class 库的一部分。

你读到的是正确的。

您需要在共享程序集内创建一个具有给定名称的纯文本 ResourceDictionary。

在您的 App.xaml 中，您可以将此 ResourceDictionary 作为 MergedDictionary 包含在内，因此您的整个应用程序将可以访问所有共享词典资源。

步骤：

创建另一个项目 WPF 控件库项目（与用户或自定义无关）
在新建项目中右击->添加->ResourceDictionary
粘贴您的样式，使其看起来如下所示：

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>

在你的主项目中引用这个新的控件库
在App.xaml参考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>

Answer 2

刚刚发现这个 post。如果您使用的是Xamarin.Forms或.NET MAUI，您也可以这样做。

我在一个共享的 class 库项目中管理我的所有样式（与接受的答案中的步骤 1-4 相同）并且添加 ResourceDictionary 如下所示。

<Application xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:KlipperRemoteControl"
             xmlns:shared="clr-namespace:AndreasReitberger.Shared;assembly=SharedMauiXamlStylesLibrary"
             x:Class="KlipperRemoteControl.App">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <shared:DefaultTheme />
            </ResourceDictionary.MergedDictionaries>                
        </ResourceDictionary>
    </Application.Resources>
</Application>

DefaultTheme.xaml 建库

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="AndreasReitberger.Shared.DefaultTheme"
    
    xmlns:ios="clr-namespace:Microsoft.Maui.Controls.PlatformConfiguration.iOSSpecific;assembly=Microsoft.Maui.Controls"
    >
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/Themes/Controls/BoxView.xaml" />
        <ResourceDictionary Source="/Themes/Controls/Editor.xaml" />
        <ResourceDictionary Source="/Themes/Controls/Entry.xaml" />
        <ResourceDictionary Source="/Themes/Controls/Label.xaml" />
        <ResourceDictionary Source="/Themes/Controls/Grid.xaml" />
        <ResourceDictionary Source="/Themes/Controls/Frame.xaml" />
       
    </ResourceDictionary.MergedDictionaries>

    <Color x:Key="Transparent">Transparent</Color>
    <Color x:Key="TappedBackgroundColor">#eaeaea</Color>

    <Color x:Key="Green">#33AD79</Color>
    <Color x:Key="LightGreen">#38ef7d</Color>
