包含的字体不会从 WPF 中的资源字典加载

Included font does not load from resource dictionary in WPF

在我的 WPF 应用程序中,我在 App.xaml 文件中包含了我正在使用的字体,如下所示:

<Application x:Class="STFAPP.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:STFAPP"
         StartupUri="Views/LoginWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        <!--Included Fonts-->
        <FontFamily x:Key="TheSans">pack://application:,,,/Style/Fonts/#TheSans</FontFamily>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Style/TextBlock.xaml"></ResourceDictionary>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

TextBlock.xaml 是包含 TextBlock 样式的资源字典:

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

<Style TargetType="{x:Type TextBlock}" x:Key="TitleStyle">
    <Setter Property="FontFamily" Value="{StaticResource TheSans}" />
    <Setter Property="FontSize" Value="15" />
</Style>

我在 TextBlock 中使用了如下样式:

<TextBlock Text="Hello" Style="{StaticResource TitleStyle}"/>

字体未加载!?

如果我避免使用单独的资源字典(TextBlock.xaml 文件)并将样式直接粘贴到 App.xaml,字体将成功加载:

<Application x:Class="STFAPP.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:local="clr-namespace:STFAPP"
         StartupUri="Views/LoginWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        <!--Included Fonts-->
        <FontFamily x:Key="TheSans">pack://application:,,,/Style/Fonts/#TheSans</FontFamily>

        <Style TargetType="{x:Type TextBlock}" x:Key="TitleStyle">
            <Setter Property="FontFamily" Value="{StaticResource TheSans}" />
            <Setter Property="FontSize" Value="15" />
        </Style>

    </ResourceDictionary>
</Application.Resources>

我想将多个资源字典文件中的样式分开来组织我的应用程序文件。

如有任何帮助,我将不胜感激

Style 中更改为 DynamicResource:

 <Setter Property="FontFamily" Value="{DynamicResource TheSans}" />

或者将 FontFamily 资源移动到 TextBlock.xaml 或另一个资源字典,例如 Fonts.xaml,并合并这个:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Style/Fonts.xaml" />
            <ResourceDictionary Source="Style/TextBlock.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>
