To compile a resource into your exe for later use:
ResourceWriter rw = new ResourceWriter("app.resources");
byte[] data = File.ReadAllBytes(scriptFile);
rw.AddResource("script", data);
rw.Close();
To retrieve that resource from the exe at runtime:
ResourceManager rm = new ResourceManager("app", Assembly.GetExecutingAssembly());
byte[] data = (byte[])rm.GetObject("script");
UTF8Encoding encoder = new UTF8Encoding();
string text = encoder.GetString(data);
Console.WriteLine(text);
