Loading images in WPF from code

Question

I must have read tons of solutions online, but for some idiotic reason I can not get them to work.

I have a .jpg image in the Resources folder of my project, and the image is set to Build Action: Resource (not embedded resource) and never copy to output folder. My image is not added to my resources.resx file.

I am trying to access the file like so:

lResult = new BitmapImage(new Uri(@"pack://application:,,,/Resources/ImageMissing.jpg", UriKind.Absolute));

But this fails saying that there is no image there.

This is so basic I feel really stupid, but I just cannot seem to grasp the simple concept of resources usage.

Thank you.

If you need to specify that the resource being referred to is referenced from the local assembly, then I would think that you would want to include "component". For example, I have some code that loads an icon from a resource available from the same assembly in which my code resides. I write this:

var SourceUri = new Uri("pack://application:,,,/MyCompany.MyProduct.MyAssembly;component/MyIcon.ico", UriKind.Absolute);
thisIcon = new BitmapImage(SourceUri);

As noted in the article available at http://msdn.microsoft.com/en-us/library/aa970069.aspx, the following additional examples illustrate the use of "component":

The following example shows the pack URI for a XAML resource file that is located in the root of the referenced assembly's project folder.

pack://application:,,,/ReferencedAssembly;component/ResourceFile.xaml

The following example shows the pack URI for a XAML resource file that is located in a subfolder of the referenced assembly's project folder.

pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml

The following example shows the pack URI for a XAML resource file that is located in the root folder of a referenced, version-specific assembly's project folder.

pack://application:,,,/ReferencedAssembly;v1.0.0.1;component/ResourceFile.xaml

Note that the pack URI syntax for referenced assembly resource files can be used only with the application:/// authority. For example, the following is not supported in WPF.

pack://siteoforigin:,,,/SomeAssembly;component/ResourceFile.xaml

You need one more comma in there. Here is the documentation on Pack URIs in WPF. Notice there are three commas when using the authority.

lResult = new BitmapImage(new Uri(@"pack://application:,,,/Resources/ImageMissing.jpg", UriKind.Absolute));
