Question

我正在尝试从WPF自定义控件库实际加载其他文件中的WPF Style 但我在这里没有加载是我的解决方案。

该解决方案包含两个项目

WPF自定义控件库的WpfTestControl
WPF应用程序库类型的WpfTestApp，它引用了WpfTestControls

来自WPF应用程序库的MainWindow.xaml

<Window.Resources>
    <Style x:Key="TempStyle" TargetType="{x:Type TextBox}">
        <Setter Property="BorderBrush" Value="Green"/>
    </Style>
</Window.Resources>
<Grid>
    <TextBox Height="50px" Width="100px" Style="{DynamicResource TempStyle}"/>
</Grid>

Generic.xaml

<ResourceDictionary
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="/WpfTestControls;component/TextBoxStyle.xaml"/>
</ResourceDictionary.MergedDictionaries>

TextBoxStyle.xaml

<ResourceDictionary 
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="TempStyle" TargetType="{x:Type TextBox}">
    <Setter Property="BorderBrush" Value="Green"/>
</Style>

我的AssemblyInfo.cs文件包含以下内容

[assembly: ThemeInfo(
ResourceDictionaryLocation.None, //where theme specific resource dictionaries are located
//(used if a resource is not found in the page, 
// or application resource dictionaries)
ResourceDictionaryLocation.SourceAssembly //where the generic resource dictionary is located
//(used if a resource is not found in the page, 
// app, or any theme specific resource dictionaries))]

但我仍然无法加载Style。如果我使用的不使用Generic.xaml，一切正常，例如以下代码按预期工作

<Window x:Class="WpfTestApp.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">

<Window.Resources>
    <Style x:Key="TempStyle" TargetType="{x:Type TextBox}">
        <Setter Property="BorderBrush" Value="Green"/>
    </Style>
</Window.Resources>
<Grid>
    <TextBox Height="50px" Width="100px" Style="{StaticResource TempStyle}"/>
</Grid>

我做错了什么？提前致谢

请为我回答一些事情......

“WPF自定义控件库”程序集与“WpfTestControls”程序集相同吗？
如果没有，那么“WPF自定义控件库”是否引用了“WpfTestControls”程序集？
您的WpfTestApp是否同时引用了“WPF自定义控件库”和“WpfTestControls”程序集？

如果添加该引用，则应正确加载资源。

我的步骤......

添加“WPF自定义控件库”，说“ThemesLibray”
在此添加“Themes”文件夹

<强> TextBoxStyle.xaml

 <ResourceDictionary 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <Style x:Key="GreenTextBoxStyle" TargetType="{x:Type TextBox}">
       <Setter Property="Background" Value="Green"/>
    </Style>
 </ResourceDictionary>

<强> Generic.xaml

  <ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <ResourceDictionary.MergedDictionaries>
         <ResourceDictionary Source="TextBoxStyle.xaml"/>
    </ResourceDictionary.MergedDictionaries>
  </ResourceDictionary>

我有一个主要的starup项目“MyWPFTestApp”，它有ThemesLibray的程序集引用。因为窗口有ThemesLibrary资源以这种方式合并....

<Window x:Class="MyWPFTestApp.Window7"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window7" Height="300" Width="300">
    <Window.Resources>
        <ResourceDictionary>
           <ResourceDictionary.MergedDictionaries>
               <ResourceDictionary
                   Source="/ThemseLibrary;component/Themes/Generic.xaml"/>    
           </ResourceDictionary.MergedDictionaries>            
        </ResourceDictionary>
    </Window.Resources>
    <Grid>
        <TextBox Style="{StaticResource GreenTextBoxStyle}"/>
    </Grid>
 </Window>

当我启动MyWPFTestApp时，我看到带有绿色TextBox的窗口。

主要是：确保将资源字典的构建操作设置为资源。

从资源文件加载WPF样式
