您可以尝试为按钮使用控件模板

之后，可以为边框定义样式以进行适当的参数设置

创建这些按钮的示例如下：

<StackPanel Orientation="Horizontal" Height="40">

    <Button Content="Stream" Width="75">
        <Button.Template>
            <ControlTemplate TargetType="Button">
                <Grid>
                    <Border CornerRadius="8,0,0,8" BorderThickness="1" BorderBrush="Black"/>
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Grid>
            </ControlTemplate>
        </Button.Template>
    </Button>

    <Button Content="Chart" Width="75" Margin="-1,0,0,0">
        <Button.Template>
            <ControlTemplate TargetType="Button">
                <Grid>
                    <Border CornerRadius="0,8,8,0" BorderThickness="1" BorderBrush="Black"/>
                    <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Grid>
            </ControlTemplate>
        </Button.Template>
    </Button>
</StackPanel>
