我有 ResourceDicionaryIcon 我存储像 DrawingBrush 这样的图标。我想将画笔颜色从 {DynamicResource GreyBrush} 更改为允许我在控件模板按钮中选择颜色（与文本颜色相同）的颜色。

<DrawingBrush x:Key="icoEdit" Stretch="Uniform">
    <DrawingBrush.Drawing>
        <DrawingGroup>
            <DrawingGroup.Children>
                <GeometryDrawing Brush="{DynamicResource GreyBrush}" Geometry="F1 M 4.95279,30.227L 11.737,37.0113L 37.5279,11.2205L 30.7437,4.43622L 4.95279,30.227 Z "/>
                <GeometryDrawing Brush="{DynamicResource GreyBrush}" Geometry="F1 M 31.7877,3.39215L 38.572,10.1764L 41.9641,6.78424L 35.1798,0L 31.7877,3.39215 Z "/>
                <GeometryDrawing Brush="{DynamicResource GreyBrush}" Geometry="F1 M 10.6276,38.096L 0,41.9641L 3.86807,31.3365L 10.6276,38.096 Z "/>
            </DrawingGroup.Children>
        </DrawingGroup>
    </DrawingBrush.Drawing>
</DrawingBrush>

实际上，我在 Canvas 中像背景一样显示图标。但这不允许我选择颜色。有没有更好的解决方案我该怎么做？

<Canvas x:Name="canvas" (...) Background="{TemplateBinding Background}" />

编辑： 

<Style x:Key="ButtonStyle" TargetType="{x:Type Button}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Button}">
                    <Grid x:Name="grid" (...)>
                        (...)

                        <TextBlock Text="{TemplateBinding Content}" (...) Foreground="{TemplateBinding Foreground}"/>
                        <Canvas x:Name="canvas" (...) Background="{TemplateBinding Background}" (...)>

                        </Canvas>
                    </Grid> 
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

<Button x:Name="Button" 
Style="{DynamicResource ButtonStyle}" 
Foreground="#FF434341" 
Background="{DynamicResource icoEdit}"  
Content="BUTTON TEXT" (...)/>

我想你应该Binding像这样向后退：

<GeometryDrawing Brush="{Binding Background, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type Canvas}}}" Geometry="F1 M 4.95279,30.227L 11.737,37.0113L 37.5279,11.2205L 30.7437,4.43622L 4.95279,30.227 Z "/>

在这里我绑定Brush到上/父元素

我现在没有 Visual Studio 来检查这个解决方案。如果我错了请纠正我
