在TextBlock上设置默认样式会导致Label和其他控件中的样式也被设置.只有将样式放在Application资源中才会发生这种情况,当我将样式放在Window资源中时,一切都很好.

我还发现VS 2008 Designer和XamlPadX会像您期望的那样显示Label,但只有在现实生活中执行应用程序时才会出现问题.

<Application x:Class="WpfApplication.App"
   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
   StartupUri="Window1.xaml">
   <Application.Resources>
       <ResourceDictionary>
           <Style TargetType="TextBlock">
               <Setter Property="FontSize" Value="8"/>
           </Style>

           <Style x:Key="Title" TargetType="Label">
               <Setter Property="FontSize" Value="32"/>
           </Style>
       </ResourceDictionary>
   </Application.Resources>
</Application>

<Window x:Class="WpfApplication.Window1"
       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
       Height="300"
       Title="Window1"
       Width="300">
   <StackPanel>

       <TextBlock Text="TextBlock No Style" Style="{x:Null}"/>
       <Label Content="Label No Style" Style="{x:Null}"/>

       <TextBlock Text="Default TextBlock"/>
       <Label Content="Default Label" Style="{StaticResource Title}"/>

   </StackPanel>
</Window>

上面的代码显示:

TextBlock No Style - Default font size (As you would expect)
Label No Style - Size 5 font size (How did this happen?)
Default …
