Question

我有2个资源字典Dictionary1.xaml和Dictionary2.xaml，其格式为TextBox和TextBlock。我在App.xaml中添加了两个字典，如下所示：

<Application
    x:Class="XAMLResources.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:XAMLResources">

    <Application.Resources>
        <SolidColorBrush x:Key="MyBrush" Color="Yellow" />

        <ResourceDictionary x:Key="dict" Source="Dictionary1.xaml"/>

        <ResourceDictionary x:Key="mergeDictionary">
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Dictionary1.xaml" />
                <ResourceDictionary Source="Dictionary2.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>

    </Application.Resources>

</Application>

现在请帮我在页面中使用这些资源：

<Page
    x:Class="XAMLResources.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"
    >
    <StackPanel Margin="20,30,0,0">
        <TextBox Margin="0" TextWrapping="Wrap" Text="TextBox" VerticalAlignment="Stretch"/>
    </StackPanel>
</Page>

在此页面中，请建议我如何在TextBox

中使用这些字典并合并字典以控制MainPage.xaml

修改 Dictionary1.xaml看起来像：

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:XAMLResources">

    <Style x:Key="eText" TargetType="TextBox">
        <Setter Property="FontSize" Value="18"/>
        <Setter Property="FontFamily" Value="Segoe WP SemiLight"/>
        <Setter Property="TextWrapping" Value="Wrap"/>
        <Setter Property="Background" Value="#FAFAFA"/>
        <Setter Property="BorderBrush" Value="#D2D2D2"/>

    </Style>
</ResourceDictionary>

我可以在UserControl或任何页面中使用此eText吗？

例如，您可以在外部文件中以下列方式定义外部资源。

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" >
    <SolidColorBrush x:Key="TitleBrush" Color="DarkViolet" />
    <SolidColorBrush x:Key="ContentBrush" Color="Black" />
</ResourceDictionary>

根据你我在App.xaml中定义了它们

<Application x:Class="App2.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:App2"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="Dictionary1.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application>

现在我在我的普通xaml页面中使用它。 TextBlock中使用的 TitleBrush 资源是相同的资源，其定义实际存在于Dictionary1.xaml中。

<Page x:Class="App2.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:App2" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"> <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}"> <Grid.ColumnDefinitions > <ColumnDefinition /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> </Grid.RowDefinitions> <StackPanel> <TextBlock FontSize="20" Foreground="{StaticResource TitleBrush}" Text="Sample text" /> </StackPanel> </Grid> </Page>
