C# - Loading image from file resource in different assembly

C# - Loading image from file resource in different assembly

I have a PNG image file which is stored in a project called SomeProject and displayed various times using XAML in that same project. In a different assembly, I now wish to access that same image. Previously I was simply specifying a relative path to the actual file which worked fine. However, when I build a release installer, the image files are packed into the SomeProject.DLL.

Is there any easy way I can access the PNG file from another assembly without simply resorting to copying the file locally to the second project? I though it might be possible using 'pack://' but I'm not having much luck.

// SomeOtherProject.SomeClass.cs ...

Image logo = new Image();
BitmapImage logoSource = new BitmapImage();
eChamSource.BeginInit();

// Following line works fine is Visual Studio, but obviously not after installation
// logoSource.UriSource = new Uri(@"..\SomeProject\Resources\Images\logo.png", UriKind.Relative);

logoSource.UriSource = new Uri("pack://application:,,,/SomeProject;component/Resources/Images/logo.png");
logoSource.EndInit();

logo.Width = 100; logo.Height = 100;
logo.Source = logoSource;

Any advice would be good.

Try to load your other assembly as followed: 

Application.LoadComponent(new Uri(@"AnotherAssembly;;;component\AnotherResourceFilePath/logo.png", UriKind.Relative)));

LoadComponent function returns an object. It is up to you to cast it to the appropriate type.

If the images you wish to use as Content is in another assembly, you must copy them to the main projects directory.

You can use a Build event to do this:

Right click project that contains images -> Properties -> Buil Events -> edit post build to copy images to main project directory.

Then you have to use it as

pack://application:,,,/ContentFile.xaml

(Or)

If you need it in subfolder

pack://application:,,,/Subfolder/ContentFile.xaml
