Wpf样式视框路径

Question

我有这样的用户控件。

Button
    Viewbox
        ContentPresenter
           Grid
               Path

我需要更改Button.Viewbox.Grid.Path.Fill颜色。

有什么办法吗？

我的Style.xaml：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style x:Key="PathStyle" TargetType="{x:Type Viewbox}">
    <!-- ?????????????????? -->
</Style>

我试过了

<Button>
    <Viewbox Width="18" Height="18" Style="{DynamicResource PathStyle}">
        <ContentPresenter Content="{Binding Converter={StaticResource uriToUIElementConverter}, ConverterParameter=Images/New.xaml}"></ContentPresenter>
    </Viewbox>
</Button>

新的

<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation">
    <Path xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="newDocument" Fill="#FF000000" Stretch="Fill">
        <Path.Data>
            <PathGeometry FillRule="Nonzero" Figures="M43,30L50.75,30 43,22.25 43,30z M52,34L39,34 39,21 24,21 24,45 20,45 20,17 43.25,17 56,29.75 56,59 34,59 34,55 52,55 52,34z M28,38L33,38 33,46 41,46 41,51 33,51 33,59 28,59 28,51 20,51 20,46 28,46 28,38z M20,59L20,52 24,52 24,55 27,55 27,59 20,59z" />
        </Path.Data>
    </Path>
</Grid>

Answer 1

嗯

<Path Fill="Red" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="newDocument" Stretch="Fill">
    <Path.Data>
        <PathGeometry FillRule="Nonzero" Figures="M43,30L50.75,30 43,22.25 43,30z M52,34L39,34 39,21 24,21 24,45 20,45 20,17 43.25,17 56,29.75 56,59 34,59 34,55 52,55 52,34z M28,38L33,38 33,46 41,46 41,51 33,51 33,59 28,59 28,51 20,51 20,46 28,46 28,38z M20,59L20,52 24,52 24,55 27,55 27,59 20,59z" />
    </Path.Data>
</Path>
