WPF重写Button样式

首先指定OverridesDefaultStyle属性为True；

然后添加样式；

重写ControlTemplate；

<Window.Resources>
    <Style x:Key="UserButtonStyle" TargetType="Button">
        <Setter Property="OverridesDefaultStyle" Value="True" />
        <Setter Property="Cursor" Value="Hand" />
        <Setter Property="Padding" Value="5 3" />
        <Setter Property="Background" Value="LightBlue" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Border Name="border" BorderThickness="0" BorderBrush="Black" Padding="{TemplateBinding Padding}" Background="{TemplateBinding Background}">
                        <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                    </Border>
                    <ControlTemplate.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Opacity" Value="0.8" />
                        </Trigger>
                    </ControlTemplate.Triggers>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
