C# - How to compute hash value for the file

using( var md5 = MD5.Create() )
using( var sha256 = SHA256.Create() )
{
  using ( FileStream stream = File.OpenRead( @"c:\_ax\3of9.ttf" ) )
  {          
    byte[] hashMD5 = md5.ComputeHash( stream );
    Console.WriteLine( BitConverter.ToString( hashMD5 ) );  

    byte[] hashSHA256 = sha256.ComputeHash( stream );
    Console.WriteLine( BitConverter.ToString( hashSHA256 ) );  
  }
}

Output:
