You can only set a a style to a specific class, so this will work (create a UserControl object, not very useful):
您只能将 aa 样式设置为特定类，因此这将起作用（创建一个 UserControl 对象，不是很有用）：
<Window.Resources>
<Style TargetType="{x:Type UserControl}">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<UserControl Name="control" Content="content"></UserControl>
</Grid>
But this doesn't (Create a class derived from UserControl):
但这不会（创建一个从 UserControl 派生的类）：
<Window.Resources>
<Style TargetType="{x:Type UserControl}">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<l:MyUserControl Name="control" Content="content"></l:MyUserControl>
</Grid>
What you can do is either explicitly set the style using the Style property:
您可以做的是使用 Style 属性显式设置样式：
<Window.Resources>
<Style TargetType="{x:Type UserControl}" x:Key="UCStyle">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<l:MyUserControl Name="control" Content="content" Style="{StaticResource UCStyle}"></l:MyUserControl>
</Grid>
or create a style for each derived class, you can use BasedOn to avoid duplicating the style content:
或者为每个派生类创建一个样式，可以使用BasedOn来避免重复样式内容：
<Window.Resources>
<Style TargetType="{x:Type UserControl}" x:Key="UCStyle">
<Setter Property="Background" Value="Red" />
</Style>
<Style TargetType="{x:Type l:MyUserControl}" BasedOn="{StaticResource UCStyle}" />
</Window.Resources>
<Grid>
<l:MyUserControl Name="control" Content="content"></l:MyUserControl>
</Grid>

I think you're missing some double quotes:
我认为您缺少一些双引号：
Try this:
尝试这个：
<Window.Resources>
<Style TargetType="{x:Type UserControl}">
<Setter Property="Background" Value="Red" />
</Style>
</Window.Resources>
<Grid>
<UserControl Name="control" Content="content"></UserControl>
</Grid>
