WPF throws “Cannot locate resource” exception when

问题:

I am having a WPF window, with a background image of one file in my local system. So the XAML file looks like this:

 <Window.Background>
    <ImageBrush ImageSource="/MYASSEMBLY;component/Resources/MyPic.png"/>
 </Window.Background>

In the XAML designer it actually shows this background image, so the image does exist in MYASSEMBLY\Resources folder. However, in the InitializeComponent() function call when I launch the application, it throws the exception

Cannot locate resource 'resources/mypic.png'.

So I am totally lost now. Are the directories different between the design and runtime so doesn't exist in the runtime?

回答1:

In the solution explore, set the image "Build Action" property to "Resource" ,then clean the solution and rebuild it.

WPF throws “Cannot locate resource” exception, this issue appeared when I was doing localisation using locbaml tool, when i compile i was getting this error. There were lots of resource merged dictionary reference So setting Build Action property of the resource xaml file to "Resource" from "Page" did resolve the issue.
