Question

我想在WPF XAML中为边框的每一边添加不同的颜色。我怎么能这样做。

<Border BorderThickness="1,2,3,4" BorderBrush="Blue"></Border>

Answer 1

有点hacky，但它确实有效。

<Grid>
    <Border BorderThickness="1,0,0,0" BorderBrush="Blue"/>
    <Border BorderThickness="0,2,0,0" BorderBrush="Red"/>
    <Border BorderThickness="0,0,3,0" BorderBrush="Green"/>
    <Border BorderThickness="0,0,0,4" BorderBrush="Orange"/>
</Grid>

创建自己的Decorator可能会更好。

Answer 2

也许？

    <DockPanel LastChildFill="True">
        <Rectangle Fill="Red" DockPanel.Dock="Top" Height="2"/>
        <Rectangle Fill="Yellow" DockPanel.Dock="Left" Width="2"/>
        <Rectangle Fill="Green" DockPanel.Dock="Right" Width="2"/>
        <Rectangle Fill="Blue" DockPanel.Dock="Bottom" Height="2"/>
        <Rectangle Fill="Wheat"/>
    </DockPanel>

Answer 3

使用四个边框https://stackoverflow.com/a/1797045/5229294

有一种hacky方式

<Border BorderThickness="0,0,0,10" BorderBrush="Green">
    <Border BorderThickness="0,0,10,0" BorderBrush="Blue">
        <Grid>
            <Button>Hello</Button>
        </Grid>
    </Border>
</Border>
