Which is best to Use for creating a file from byte[]?

I want to create a file using byte[], which one is best.

byte[] content=File.ReadAllBytes(@"C:\ServiceLog.txt");

FileStream stream = new FileStream(@"C:\ServiceLog1.txt", FileMode.Create, FileAccess.ReadWrite);
stream.Write(content, 0, content.Length);
stream.Close();

or

 File.WriteAllBytes(@"C:\12.txt",content);
