ImageBrush throws exception when trying to set Window background
提问by user1683456
I'm trying to set the background of my WPF window to an image but I'm getting this exception when I try to run it:
我正在尝试将 WPF 窗口的背景设置为图像，但是当我尝试运行它时出现此异常：
A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll Additional information: 'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.' Line number '8' and line position '10'.
A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in PresentationFramework.dll Additional information: 'Provide value on 'System.Windows.Baml2006.TypeConverterMarkupExtension' threw an exception.' Line number '8' and line position '10'.
I don't want to add the image to the project, as I would like to be able to change the image at runtime. My intention is to use databinding to set the background picture during start-up once I have this bit working.
我不想将图像添加到项目中，因为我希望能够在运行时更改图像。我的目的是在启动过程中使用数据绑定来设置背景图片，一旦我开始工作。

Wrong. It should be set to CONTENT not Resource.
错误的。它应该设置为内容而不是资源。
Include in your project (use the file explorer)
包含在您的项目中（使用文件浏览器）
Right click on the image > Properties > Advanced.
右键单击图像 > 属性 > 高级。
Build Action: Content
构建操作：内容
Copy to Output Directory: Copy always.
复制到输出目录：始终复制。

Your image's build action is probably set to Content, change it to Resource
您的图像的构建操作可能设置为内容，将其更改为资源
Set the item (your image file) to be a Resource. (In Visual Studio) Right click,Properties,Build Action,Resource
将项目（您的图像文件）设置为资源。（在 Visual Studio 中）右键单击，属性，构建操作，资源

I had the same problem with
我有同样的问题
<Button>
<Button.Background>
<ImageBrush ImageSource="/Resources/icon_done.png">
</Button.Background>
</Button>
I used /before Resources and it work correctly, but i used solution with properties image ->Properties->Build to Resources.
These two actions solved my issue.
我/之前使用过 Resources 并且它工作正常，但我使用了带有属性 image 的解决方案->Properties->Build to Resources。这两个动作解决了我的问题。

Add the forward "/" to the location
将向前的“/”添加到位置
Then the whole ImageSource string should look like
然后整个 ImageSource 字符串应该看起来像
<ImageBrush ImageSource="/Resources/Image1.png" Stretch="None" />
