Think about it, there is no miracle. You want to take data from a file and put your content inside your code. In the end this data remains saved somewhere - in its sources or binaries. So, why do you care?
Add this file to the project, check to always copy the file in the builds and touch the solution. Now, if you really want to do this:
Read the file data, create a buffer and then create that buffer as C # code.
var buffer = File.ReadAllBytes(caminhoDoArquivoBinario);
System.Diagnostics.Debugger.Break(); // breakpoint após a leitura do buffer
Then go to Imediate Window
and do:
buffer <ENTER>
Copy what was generated and paste into some .cs
