Background Image of Button not showing in WPF
提问by Андрей Про
I have program in which I have lots of buttons. Each of button has background set as
我有一个程序，其中有很多按钮。每个按钮的背景设置为
<Button x:Name="mybutton" HorizontalAlignment="Left" Height="30" Margin="76,110,0,0" VerticalAlignment="Top" Width="25" Click="some_click">
<Button.Background>
<ImageBrush ImageSource="Resource/button_picture.png"/>
</Button.Background>
</Button>
Image is showing as background in .xamlwhen program not running but when i run application image is not there as background of button. How do i debug this background in button ? Is there any goofy error that is there?
当程序未运行时，图像在.xaml 中显示为背景，但当我运行应用程序时，图像不存在作为按钮的背景。我如何在按钮中调试这个背景？是否有任何愚蠢的错误？

Let's make sure we have the following properties set right in your scenario
让我们确保我们在您的场景中正确设置了以下属性
1) Build Action -> Resource
1) 构建动作 -> 资源
2) Copy to Output Directory -> Do not copy
2) 复制到输出目录 -> 不要复制
3) Instead of using the relative path for image source, try using a full path to the image like this (I say this because I don't know where the image resource is located in your project, using relative path is perfectly normal in WPF)
3）不要使用图片源的相对路径，尝试使用图片的完整路径这样)
<Image Source="pack://application:,,,/AssemblyNameContainingImageResource;component/Resource/button_picture.png" />

Change the Build Action of button_picture.png to Resource if it is content. Also check the Copy to output directory property value
如果是内容，将button_picture.png 的Build Action 改为Resource。还要检查复制到输出目录属性值
