问题描述
在我的WPF应用程序中,我在App.xaml
文件中包括了正在使用的字体,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
是一种资源字典,包含TextBlock
样式:
<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
中使用了以下样式:
<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
,则字体将成功加载:
<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>
感谢您的帮助
解决方法
在DynamicResource
中更改为Style
:
<Setter Property="FontFamily" Value="{DynamicResource TheSans}" />
或者将FontFamily
资源移动到TextBlock.xaml
或其他资源字典中,例如Fonts.xaml
,然后将其合并:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Style/Fonts.xaml" />
<ResourceDictionary Source="Style/TextBlock.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
