我正在尝试为ComboBox添加一个资源字典,并且在我应用了stlye之后出现了这个错误(样式赢了' t / show):
未处理的类型异常 ' System.Windows.Markup.XamlParseException'发生在 PresentationFramework.dll
其他信息:找不到已命名的资源 ' ComboBoxFocusVisual&#39 ;.资源名称区分大小写。
可能出了什么问题?我尝试重新加载项目并构建它。
这是我的代码:

在ComboBox样式上方添加以下缺少的样式:
<Style x:Key="FocusVisual">
<Setter Property="Control.Template">
<Setter.Value>
<ControlTemplate>
<Rectangle Margin="2" SnapsToDevicePixels="true" Stroke="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" StrokeThickness="1" StrokeDashArray="1 2"/>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
您当然需要定义“ButtonNormalBackground”,“ButtonNormalBorder”以及您引用的所有其他资源。你应该能够从你获得风格的那个地方得到这些......

我对类似的错误感到沮丧,发现定义资源的 SEQUENCE 至关重要。您需要确保定义最低级别的资源,然后在资源文件顶部的其他资源(例如颜色)中引用这些资源。
