How can I set the WPF BitmapImage UriSource property to a relative path?

Question

I'm loading an image in WPF by using the BitmapImage class. My code works perfectly when I give an absolute path for the UriSource but not when I try and use a relative path.

My XAML is:

<Image Width="50" Name="MemberImage" HorizontalAlignment="Left">
    <Image.Source>
        <BitmapImage DecodePixelWidth="50" UriSource="questionmark.jpg" />
    </Image.Source>
</Image>

The questionmark.jpg is added to the project with a Build Action of Resource and Copy to Output Directory set to Copy always. The error I get is "The file [file name] is not part of the project or its 'Build Action' property is not set to 'Resource'". This works when I use an absolute path for the UriSource but that obviously won't do.

How should I be defining my UriSource in the XAML?

Answer 1

I cannot reproduce the problem on my computer:

• I add the jpg by choosing Add existing item in the Project menu
• I then set its Build Actio to Resource and Copy to Output directory to always.
• My XAML is the same.

Works perfectly here, even after moving the .exe and renaming the jpg. Something else must be biting you!
