您可以设置背景：

<Separator Background="Red"/>

You can set the Background:

<Separator Background="Red"/>

嗯...我认为 Separator 是少数无法使用简单样式的元素之一。根据MSDN文档，您需要指定SeparatorStyleKey。

例如，对于 ToolBar 您可以这样做：

<Style x:Key="{x:Static ToolBar.SeparatorStyleKey}" 
    TargetType="{x:Type Separator}">
    <Setter Property="Background" 
        Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
    <Setter Property="Margin" Value="0,2,0,2"/>
    <Setter Property="Focusable" Value="false"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Separator}">
                <Border 
                    BorderBrush="{TemplateBinding BorderBrush}" 
                    BorderThickness="{TemplateBinding BorderThickness}" 
                    Background="{TemplateBinding Background}" 
                    Height="1" 
                    SnapsToDevicePixels="true"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

Hmm... I think the Separator is one of the few elements that will not work using a simple style. Based on the MSDN documentation, you need to specify the SeparatorStyleKey.

For instance for a ToolBar you would do this:

<Style x:Key="{x:Static ToolBar.SeparatorStyleKey}" 
    TargetType="{x:Type Separator}">
    <Setter Property="Background" 
        Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
    <Setter Property="Margin" Value="0,2,0,2"/>
    <Setter Property="Focusable" Value="false"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type Separator}">
                <Border 
                    BorderBrush="{TemplateBinding BorderBrush}" 
                    BorderThickness="{TemplateBinding BorderThickness}" 
                    Background="{TemplateBinding Background}" 
                    Height="1" 
                    SnapsToDevicePixels="true"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

使用样式

    <Style x:Key="MySeparatorStyle" TargetType="{x:Type Separator}">
        <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
        <Setter Property="Margin" Value="0,2,0,2"/>
        <Setter Property="Focusable" Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Separator}">
                    <Border 
                        BorderBrush="{TemplateBinding BorderBrush}" 
                        BorderThickness="{TemplateBinding BorderThickness}" 
                        Background="{TemplateBinding Background}" 
                        Height="1" 
                        SnapsToDevicePixels="true"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

分隔符只是一个边框元素，现在您可以按照自己喜欢的方式更改其外观？

Use styles

    <Style x:Key="MySeparatorStyle" TargetType="{x:Type Separator}">
        <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}"/>
        <Setter Property="Margin" Value="0,2,0,2"/>
        <Setter Property="Focusable" Value="false"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Separator}">
                    <Border 
                        BorderBrush="{TemplateBinding BorderBrush}" 
                        BorderThickness="{TemplateBinding BorderThickness}" 
                        Background="{TemplateBinding Background}" 
                        Height="1" 
                        SnapsToDevicePixels="true"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

A seperator is just a border element and now you can change its appearance any way you like?
