我想使用Aero文本框样式,但仍会覆盖某些属性。我试图通过以下方式实现这一目标:
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/PresentationFramework.Aero, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml" />
</ResourceDictionary.MergedDictionaries>
<Style x:Key="{x:Type TextBox}" TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
<Setter Property="Margin" Value="2" />
<Setter Property="Padding" Value="2" />
</Style>
</ResourceDictionary>
但是,这会在启动我的应用时产生StackOverflowException
。
当我删除对PresentationFramework.Aero的引用时,这可以工作,但我得到了默认的操作系统样式,这使得应用程序很难看。 ;)
所以,实际上:如果我想在我的所有文本框上覆盖一些样式,我就无法获得Aero外观。如果我想要Aero外观,我无法覆盖任何样式。死锁。
有什么方法可以解决这个问题吗?

如果将Style
作为较低级别的资源而不是在同一ResourceDictionary中,它似乎有效:
<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="/PresentationFramework.Aero, Version=3.0.0.0, Culture=Neutral, PublicKeyToken=31bf3856ad364e35, ProcessorArchitecture=MSIL;component/themes/aero.normalcolor.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Grid.Resources>
<Border BorderBrush="Blue" BorderThickness="3">
<Border.Resources>
<Style TargetType="{x:Type TextBox}" BasedOn="{StaticResource {x:Type TextBox}}">
<Setter Property="Margin" Value="2" />
<Setter Property="Padding" Value="2" />
</Style>
</Border.Resources>
<TextBox />
</Border>
</Grid>

与接受答案中的代码不同,这个允许使用资源字典来表示样式。被 Vivien Ruitz回答的http://social.msdn.microsoft.com/forums/en-US/wpf/thread/3c66adb7-fd26-40c7-8404-85f6fefbd392/无耻地偷走
