I am trying to run some sample code but I am having some trouble loading a resource file (Level.bin) into the assembly so that I can extract data from the file at runtime using the code:

Stream stream = GetType().Assembly.GetManifestResourceStream("Level.bin");
Byte[] data = new Byte[stream.Length];
stream.Read(data, 0, (int) stream.Length);

An exception is caught on the 2nd line stating that object reference is not set to an instance of an object. The GetManifestResourceStream() method is not throwing an exception but it appears that there is never an object stream created.
I have added the file Level.bin to the project and set the build action to Embedded Resource.
Is there anything that I am missing?

Thanks,
Einar
