Use styles
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>
A seperator is just a border element and now you can change its appearance any way you like?
分隔符只是一个边框元素，现在您可以随心所欲地更改其外观吗？

Hmm... I think the Separatoris one of the few elements that will not work using a simple style. Based on the MSDN documentation, you need to specify the SeparatorStyleKey.
嗯...我认为这Separator是少数几个不能使用简单样式的元素之一。根据 MSDN 文档，您需要指定SeparatorStyleKey.
For instance for a ToolBaryou would do this:
例如对于 aToolBar你会这样做：
<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>

you can set the Separator's color using this code:
您可以Separator使用以下代码设置的颜色：
<Separator BorderBrush="Red" BorderThickness="1"/>
<Separator BorderBrush="Red" BorderThickness="1"/>
NOTE that the BorderThicknessproperty must be applied too.
请注意，该BorderThickness属性也必须被应用。

Alternatively you could choose to use a Rectangle element:
或者，您可以选择使用 Rectangle 元素：
<Rectangle HorizontalAlignment="Stretch" Fill="Blue" Height="2"/>
<Rectangle HorizontalAlignment="Stretch" Fill="Blue" Height="2"/>
It's somewhat easier to modify/shape.
修改/塑造更容易一些。
