WPF跨程序集共享资源

WPF跨程序集共享资源

1.添加资源

1.1 添加WPFCustomControlLibrary项目

1.2 在WPFCustomControlLibrary项目下添加资源字典

本例子是直接在默认创建的Themes文件夹添加ResourceDictionary，也可以在该项目下另外新建文件夹，并在此文件下添加ResourceDictionary

1.3 编写资源文件里的内容

• ButtonDictionary.xaml

 <Style x:Key="ButtonStyle1" TargetType="{x:Type Button}">
        <Setter Property="FocusVisualStyle" Value="{StaticResource FocusVisual}"/>
        <Setter Property="Background" Value="{StaticResource Button.Static.Background}"/>
        <Setter Property="BorderBrush" Value="{StaticResource Button.Static.Border}"/>
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}"/>
        <Setter Property="BorderThickness" Value="1"/>
        <Setter Property="HorizontalContentAlignment" Value="Center"/>
        <Setter Property="VerticalContentAlignment" Value="Center"/>
        <Setter Property="Padding" Value="1"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding     BorderThickness}" 
                            Background="{TemplateBinding Background}" SnapsToDevicePixels="true">
                        <ContentPresenter x:Name="contentPresenter" Focusable="False" 
                                          HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" 
                                          Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" 
                                          SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" 
                                          VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsDefaulted" Value="true">
                            <Setter Property="BorderBrush" TargetName="border" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}"/>
                        </Trigger>
                        <Trigger Property="IsMouseOver" Value="true">
                            <Setter Property="Background" TargetName="border" Value="{StaticResource Button.MouseOver.Background}"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.MouseOver.Border}"/>
                        </Trigger>
                        <Trigger Property="IsPressed" Value="true">
                            <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Pressed.Background}"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Pressed.Border}"/>
                        </Trigger>
                        <Trigger Property="IsEnabled" Value="false">
                            <Setter Property="Background" TargetName="border" Value="{StaticResource Button.Disabled.Background}"/>
                            <Setter Property="BorderBrush" TargetName="border" Value="{StaticResource Button.Disabled.Border}"/>
                            <Setter Property="TextElement.Foreground" TargetName="contentPresenter" Value="{StaticResource Button.Disabled.Foreground}"/>
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

• BrushDictionary.xaml

   <ImageBrush x:Key="img"  ImageSource="/WpfCustomControlLibrary;Component/Icon/facebook_64px.png" TileMode="Tile" 
                    Viewport="0 0 20 20" ViewportUnits="Absolute"/>

本例子中添加了2个资源字典分别是ButtonDictionary和BrushDictionary

2.使用资源

2.1在需要使用资源的项目中添加WPFCustomControlLibrary的引用

2.2合并资源字典

2.3使用资源

<Button Grid.Row="2" Style="{StaticResource ButtonStyle1}">
            Hello
</Button>
<Button Background="{StaticResource img}" Grid.Row="3" Margin="20">
            img
</Button>

实现效果

其实图片资源也可以使用本方法实现跨程序集共享

把资源分离出来管理，可以使业务更加的清晰，也方便管理资源，和在本程序集使用资源没有区别
