You can customize the template of the scrollviewer to change the position of the scrollbar(s) (among other things). The MSDN example of template customisation is actually showing how to move the vertical scrollbar to the left.
您可以自定义滚动查看器的模板以更改滚动条的位置（除其他外）。模板定制的MSDN示例实际上是在展示如何将垂直滚动条向左移动。

Here is the code for convenience:
为方便起见，代码如下：
<Style x:Key="LeftScrollViewer" TargetType="{x:Type ScrollViewer}">
<Setter Property="OverridesDefaultStyle" Value="True"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollViewer}">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<ScrollContentPresenter Grid.Column="1"/>
<ScrollBar Name="PART_VerticalScrollBar"
Value="{TemplateBinding VerticalOffset}"
Maximum="{TemplateBinding ScrollableHeight}"
ViewportSize="{TemplateBinding ViewportHeight}"
Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}"/>
<ScrollBar Name="PART_HorizontalScrollBar"
Orientation="Horizontal"
Grid.Row="1"
Grid.Column="1"
Value="{TemplateBinding HorizontalOffset}"
Maximum="{TemplateBinding ScrollableWidth}"
ViewportSize="{TemplateBinding ViewportWidth}"
Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

The scrollbar position is defined by the FlowDirection property.
滚动条位置由 FlowDirection 属性定义。

The above code is to change from right to left. However, you need from left to Right. Use same code as above but change the scrollcontent presenter to this:
上面的代码是从右到左的变化。但是，您需要从左到右。使用与上面相同的代码，但将滚动内容演示者更改为：
<ScrollContentPresenter x:Name="PART_ScrollContentPresenter" Grid.Column="0" Grid.Row="0"/>
