本人想设置Button为圆角，修改奈何搜索百度，圆角找到的经典全是坑爹答案，现总结如下：

1. 需要添加button 的修改template.

2. 设置border的时候，服务器租用必须要设置background,圆角 否则会提示content 被多次使用。

<Button Grid.Row="3" Grid.Column="2" Content="取消" Margin="30,经典40,200,40" >                 <Button.Template >                     <ControlTemplate TargetType="{ x:Type Button}" >                         <Border BorderBrush="{ TemplateBinding Control.BorderBrush}" BorderThickness="1" CornerRadius="7,7,7,7">                             <Border.Background>#FFDDDDDD</Border.Background>                             <ContentPresenter Content="{ TemplateBinding ContentControl.Content}" HorizontalAlignment="Center" VerticalAlignment="Center" ></ContentPresenter>                         </Border>                     </ControlTemplate>                 </Button.Template>             </Button> 

我们只需要在XAML中给他添加几行代码就可以做成圆角形状。

<Button x:Name="button" Content="按钮" FontSize="40" BorderThickness="0" HorizontalAlignment="Left" Margin="25,修改58,0,0" VerticalAlignment="Top" Width="472" Height="200" Foreground="White">       <Button.Template>            <ControlTemplate TargetType="{ x:Type Button}">                <Border BorderThickness="1" BorderBrush="Black" CornerRadius="30" Background="{ TemplateBinding Background}">                    <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center"/>                </Border>            </ControlTemplate>        </Button.Template> </Button> 

属性解析：

BorderThickness：边框的大小

BorderBrush：边框的颜色

CornerRadius：圆角的大小

Background：背景颜色"{ TemplateBinding Background}"：这个就是使用上面<Button>的云服务器提供商Background属性值作为他的值

<ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center"/>：文字垂直居中对齐

加个渐变色

<Button x:Name="button" Content="按钮" FontSize="40" BorderThickness="0" HorizontalAlignment="Left" Margin="25,58,0,0" VerticalAlignment="Top" Width="472" Height="200" Foreground="White">             <Button.Background>                 <LinearGradientBrush EndPoint="1,1" StartPoint="0,0">                     <GradientStop Color="#FFC564B8" Offset="0"/>                     <GradientStop Color="#FFF57A7A" Offset="1"/>                 </LinearGradientBrush>             </Button.Background>             <Button.Template>                 <ControlTemplate TargetType="{ x:Type Button}">                     <Border BorderThickness="1" CornerRadius="30" Background="{ TemplateBinding Background}">                         <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center"/>                     </Border>                 </ControlTemplate>             </Button.Template>         </Button> 

如图：

把样式和空间模板放到资源中，然后去引用
