WPF 制作圆角按钮

在程序对应坐置插入以下代码，或是先拖一个按钮控件到窗体中，再替换对应的代码。

修改 CornerRadius="18,3,18,3"  就可以改变圆角大小

按钮效果：

 <Button Content="Button" HorizontalAlignment="Left" Margin="19,10,0,0" VerticalAlignment="Top" Width="75" Height="59">
            <Button.Template>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Border BorderBrush="{TemplateBinding Control.BorderBrush}" BorderThickness="0" CornerRadius="18,3,18,3" Name="PART_Background">
                        <Border.Background>
                            <LinearGradientBrush EndPoint="0,1" StartPoint="0,0">
                                <GradientStop Color="#33CC33" Offset="0.0" />
                                <GradientStop Color="Orange" Offset="0.5" />
                                <GradientStop Color="LightYellow" Offset="0.0" />
                            </LinearGradientBrush>
                        </Border.Background>
                        <ContentPresenter Content="{TemplateBinding ContentControl.Content}" HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="UIElement.IsMouseOver" Value="True">
