In WPF how do I specify the path to a file nested in a Directory using XAML?
提问by Doug
I am trying to do this...
我正在努力做到这一点......
<Image x:Name="imgGroupImage" Source="Images\unlock.png" Margin="0,0,5,0" />
But I get this error...
但我收到这个错误...
Cannot convert string 'Images\unlock.png' in attribute 'Source' to object of type 'System.Windows.Media.ImageSource'. Cannot locate resource 'forms/images/unlock.png'. Error at object 'System.Windows.HierarchicalDataTemplate' in markup file 'Fuse;component/forms/mainwindow.xaml' Line 273 Position 51.
无法将属性“Source”中的字符串“Images\unlock.png”转换为“System.Windows.Media.ImageSource”类型的对象。无法找到资源“forms/images/unlock.png”。标记文件“Fuse;component/forms/mainwindow.xaml”第 273 行第 51 行中的对象“System.Windows.HierarchicalDataTemplate”出错。
As you can see, my form that includes this XAML is in a folder named Forms. My Images are in a folder named Images. How do I map from Forms to Images?
如您所见，包含此 XAML 的表单位于名为 Forms 的文件夹中。我的图像位于名为图像的文件夹中。如何从表单映射到图像？
I tried Source="..Images\unlock.png"which does not work in WPF.
我试过Source="..Images\unlock.png"哪个在 WPF 中不起作用。
Any help?
有什么帮助吗？

- Add your image to the Project in VS
- Right click on that image unlock.png
- Go to Context menu /Properties
- Change Build Action to Resource
- 将您的图像添加到 VS 中的项目
- 右键单击该图像unlock.png
- 转到上下文菜单/属性
- 将构建操作更改为资源
Thats it :-)
就是这样 ：-）

In order to use resource located in folder different that the one where your XAML is, do this:
为了使用位于与 XAML 所在文件夹不同的文件夹中的资源，请执行以下操作：
<Image Source="pack://application:,,,/Resources/image.png"/>
Where Resourcesis name of directory which you want to use resources from and image.png isname of image to display. Answer found thanks to @matt-hamilton and @brian-hinchey and their mention of Pack URI.
Works perfectly with your own Converters. You just have to return string matching schema above.
其中Resources是您要使用资源的目录名称，而image.png 是要显示的图像名称。感谢@matt-hamilton 和@brian-hinchey 以及他们对 Pack URI 的提及找到了答案。
与您自己的转换器完美配合。您只需要返回上面的字符串匹配模式。

Have you tried setting the source to a BitmapImage?
您是否尝试将源设置为BitmapImage？
<Image x:Name="imgGroupImage" Margin="0,0,5,0" >
<Image.Source>
<BitmapImage UriSource="Images/unlock.png" />
</Image.Source>
</Image>
I believe the default type of Urifor UriSourceis a relative Uri, which works off the application's base class. You might find you can configure the BitmapSourcea bit easier than trying to find the exact way you have to enter the file path in the Sourceattribute.
我相信Urifor的默认类型UriSource是 relative Uri，它适用于应用程序的基类。您可能会发现，BitmapSource与尝试找到在Source属性中输入文件路径的确切方式相比，您可以更轻松地配置它。
