c# - Resource from assembly as a stream

Question

I have an image in a C# WPF app whose build action is set to 'Resource'. It's just a file in the source directory, it hasn't been added to the app's resource collection through the drag/drop properties dialog. I'm trying to write it as a stream, but I can't open it despite trying quite a few variations of dots, slashes, namespaces and seemingly everything else.

I can access it to use elsewhere either in xaml with "pack://application:,,,/Resources/images/flags/tr.png", but I can't get at a stream containing it.

Most places seem to say use

using(BinaryReader reader = new BinaryReader(System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream("ResourceBlenderExpress.Resources.images.flags.tr.png"))) {
    using(BinaryWriter writer = new BinaryWriter(File.OpenWrite(imageFile))) {
        while((read = reader.Read(buffer, 0, buffer.Length)) > 0) {
            writer.Write(buffer, 0, read);
        }
        writer.Close();
    }
    reader.Close();
}

Which I haven't had any luck with.

You're probably looking for Application.GetResourceStream

StreamResourceInfo sri = Application.GetResourceStream(new Uri("Images/foo.png"));
if (sri != null)
{
    using (Stream s = sri.Stream)
    {
        // Do something with the stream...
    }
}
