【问题描述】：
我正在组合一个非常简单的 WPF 窗口来演示最终用户所要求的样式的外观。由于有许多重复的按钮类型对象，我想让它们在窗口中具有一种样式，一旦进行了调整，就可以将其转移到实际应用程序中。
我面临的问题是用户希望为他们的按钮提供图像，当我在按钮本身内设置背景图像时，它会完美显示并按我想要的方式运行（鼠标悬停时更改图像等）。当我将该格式移动到样式中时，一切正常，但背景图像不显示。我确定我遗漏了一些非常简单的东西，但我看不到它。
我生成的代码如下：-
<Window x:Class="SkinningDemo.MainWindow"

<TextBlock HorizontalAlignment="Left" Height="56" TextWrapping="Wrap" TextAlignment="Center" VerticalAlignment="Top" Width="311" Margin="56,294,0,0" Foreground="#FF220A88"><Run Language="en-gb" Text="Third Functional Text will go here"/></TextBlock>
<TextBlock HorizontalAlignment="Left" Height="56" TextWrapping="Wrap" TextAlignment="Center" VerticalAlignment="Top" Width="311" Margin="446,295,0,0" Foreground="#FF220A88"><Run Language="en-gb" Text="Fourth functional text will go here..."/></TextBlock>
<Button x:Name="Button3" Style="{StaticResource MainButtonStyle}" Content="View Function 3" HorizontalAlignment="Left" Height="50" Margin="472,343,0,0" VerticalAlignment="Top" Width="258" FontSize="18"/>
<Button x:Name="Button4" Style="{StaticResource MainButtonStyle}" Content="View Function 4" HorizontalAlignment="Left" Height="50" Margin="80,343,0,0" VerticalAlignment="Top" Width="258" FontSize="18"/>
</Grid>
</Window>
正如我所说的，背景图像不会显示在屏幕上，但是如果我删除样式并将其全部设置在本地并使用完全相同的值，它就可以完美地工作：-
<Button x:Name="Button1" Content="View Function 1" HorizontalAlignment="Left" Height="50" Margin="82,205,0,0" VerticalAlignment="Top" Width="258" FontSize="18">
<Button.Background>
<ImageBrush ImageSource="/Images/Button1.png"/>
</Button.Background>
</Button>
感谢期待帮助。
