Question

我的wpf应用程序中存在一个小问题。我有两个课程GameObject和Block。两者都是CustomControl s，GameObject直接来自Control，Block来自GameObject。我想写一个基于GameObject样式的样式。这是一段代码

<Style TargetType="{x:Type primitives:GameObject}" x:Key="game">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type primitives:GameObject}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="Grid.Row" Value="{Binding Path=Row, RelativeSource={RelativeSource Self}}"/>
    <Setter Property="Grid.Column" Value="{Binding Path=Column, RelativeSource={RelativeSource Self}}"/>
</Style>

<Style TargetType="{x:Type primitives:Block}" BasedOn="{StaticResource game}"> 
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type primitives:Block}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

但是，如果我在第一个样式中添加x:Key，它将不会自动应用于GameObject的每个实例，因此我的Style在程序中的其他文件中无用。任何想法该怎么做？

你仍然可以将它应用于所有特定的，你只需要一种可以反映它的全局风格。

<Style TargetType="{x:Type primitives:GameObject}" x:Key="game">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type primitives:GameObject}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
    <Setter Property="Grid.Row" Value="{Binding Path=Row, RelativeSource={RelativeSource Self}}"/>
    <Setter Property="Grid.Column" Value="{Binding Path=Column, RelativeSource={RelativeSource Self}}"/>
</Style>

<Style TargetType="{x:Type primitives:Block}" BasedOn="{StaticResource game}"> 
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type primitives:Block}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<Style TargetType="{x:Type primitives:GameObject}" BasedOn="{StaticResource game}">
</Style>

如果您需要在范围（object.resources）或全局范围内应用命名样式，则基于OnOn有一定的可能性。

基于未命名的风格
