Line in style 的 TargetType 在 UWP 中不起作用 [英] The TargetType for Line in style doesn't work in UWP

问题描述

我有以下代码:

<Grid>
    <Grid.Resources>
        <Style TargetType="Line">
            <Setter Property="Stroke" Value="Black"></Setter>
            <Setter Property="StrokeDashArray" Value="3"></Setter>
            <Setter Property="StrokeThickness" Value="3"></Setter>
        </Style>
    </Grid.Resources>
    <Line X1="20" X2="500" Y1="50" Y2="50"></Line>
    <Line X1="20" X2="500" Y1="100" Y2="100"></Line>
    <Line X1="20" X2="500" Y1="150" Y2="150"></Line>
</Grid>

您可以看到屏幕截图，样式中的 StrokeDashArray 属性值仅应用于第一行.为什么?

You could see the screenshoot, the StrokeDashArray property value in the style only appled to the first line. Why?

推荐答案

我可以重现这个问题，但我不确定是什么导致了这种意外行为.我会向团队询问这个问题.作为一种解决方法，您可以使用 StaticResource 来共享 StrokeDashArray 的值.

I could reproduce this issue, but I'm not sure what caused this unexpected behavior. I'll ask the team about this issue. As a workaround, you could use StaticResource for sharing the value of StrokeDashArray.

<Grid>
    <Grid.Resources>
        <Style TargetType="Line">
            <Setter Property="Stroke" Value="Black"></Setter>
            <Setter Property="StrokeThickness" Value="3"></Setter>
        </Style>
        <x:String x:Key="strokeArray">3</x:String>
    </Grid.Resources>
    <Line X1="20" X2="500" Y1="50" Y2="50" StrokeDashArray="{StaticResource strokeArray}"></Line>
    <Line X1="20" X2="500" Y1="100" Y2="100" StrokeDashArray="{StaticResource strokeArray}"></Line>
    <Line X1="20" X2="500" Y1="150" Y2="150" StrokeDashArray="{StaticResource strokeArray}"></Line>
</Grid>
