两次引用路径资源会导致崩溃 [英] Referencing a path resource twice causes a crash
本文介绍了两次引用路径资源会导致崩溃的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
任何人都可以告诉我这不起作用：
Can anyone tell my this isn't working:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="test8.MainWindow"
x:Name="Window"
Title="MainWindow"
Width="640" Height="480">
<Window.Resources>
<Path x:Key="myPath" Fill="White" Stretch="Fill" Stroke="Black" Width="90.25" Height="41.187" Data="M3,-26.5 L-40,-20 -25.5,-2.75 18.5,2.875 49.25,-13.3125 12.625,-12.3125 27.625,-37.3125 z"/>
</Window.Resources>
<Grid x:Name="LayoutRoot">
<Button Margin="178,79,211,0" VerticalAlignment="Top" Height="84" Content="{StaticResource myPath}"/>
<Button Margin="178,79,211,0" VerticalAlignment="Top" Height="84" Content="{StaticResource myPath}"/>
</Grid>
</Window>
它构建，但运行时崩溃。
看起来特别奇怪我，因为sollowing工作完美：
It builds, but the crashes when run.
It seems especially weird to me since the sollowing works perfectly:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Class="test8.MainWindow"
x:Name="Window"
Title="MainWindow"
Width="640" Height="480">
<Window.Resources>
<Path x:Key="myPath" Fill="White" Stretch="Fill" Stroke="Black" Width="90.25" Height="41.187" Data="M3,-26.5 L-40,-20 -25.5,-2.75 18.5,2.875 49.25,-13.3125 12.625,-12.3125 27.625,-37.3125 z"/>
</Window.Resources>
<Grid x:Name="LayoutRoot">
<Button Margin="178,79,211,0" VerticalAlignment="Top" Height="84" Content="{StaticResource myPath}"/>
<!-- Removing the following line is the only change here -->
<!-- <Button Margin="178,79,211,0" VerticalAlignment="Top" Height="84" Content="{StaticResource myPath}"/> -->
</Grid>
</Window>
推荐答案
这是生成的输出通过崩溃的应用程序：
