File.WriteAllBytes creating 0 byte files

Is it possible for this combination of lines to create a 0 byte file? I would expect the write to always complete. Thanks!

File.WriteAllBytes(file_name, encrypted_data);
encrypted_data = null;

Edit: assuming my byte array isn't empty of course, which I am adding checks for.

try to user writeByte instead of File.WriteAllBytes

FileStream stream = File.Open(FilePath,FileMode.OpenOrCreate);            
                   if (null != stream)
                   {
                       byte[] encrypted_data=something; // your bytes
                       foreach (byte b in encrypted_data)
                       {
                           stream.WriteByte(b);
                       }
                   }
stream.Close();

you can still use System.IO.File.ReadAllBytes when you read file
