我需要将所有路径保存在画布中，以便轻松检索它们。我发现它适用于VisualBrush. 当我尝试检索VisuahBrush并放入Styles时，它有错误：

该类型的对象System.Windows.Media.VisualBrush不能应用于需要该类型的属性Systems.Windows.Style。

我还能如何将所有路径保存在画布中并且仍然可以在Styles 中检索？

任何想法都会有很大帮助，谢谢！

<VisualBrush x:Key="myVisualBrush">
    <VisualBrush.Visual>
        <Canvas>
            <Path Fill="#FF231F20" Stretch="Fill" Width="12.69" Height="14.477" Canvas.Left="652.196" Canvas.Top="88.61" Data="F1M617.2051,52.7275C616.7281,52.4525,616.3391,52.6775,616.3391,53.2275L616.3391,66.4695C616.3391,67.0195,616.7281,67.2445,617.2051,66.9695L628.6721,60.3485C629.1481,60.0735,629.1481,59.6235,628.6721,59.3485z"/>
        </Canvas>
    </VisualBrush.Visual>
</VisualBrush>

<Style x:Key="myVisualStyle" BasedOn="{StaticResource myVisualBrush}" TargetType="{x:Type TextBox}">
    <!-- Styles -->
</Style>

您的 VisualBrush 旨在分配给接受画笔的对象，例如背景而不是您尝试的样式。我建议你做这样的事情。（如果你需要能够挑选和选择你的画笔，这个例子将为VisualBrush每个人分配相同的东西，那么我建议你添加回你的样式并将样式单独分配给你的文本框的TextBoxx:Key）
