'x' or 'x' means express the number in hexadecimal string format. If it's a lower case 'x' then the hex digits higher than 9 (i.e. abcdef) appear in lower case . If it's an upper case 'X' then they appear as 'ABCDEF'. The '2' means express as (at least) two hex digits and use a leading zero if there's only one digit required to express the number. For example decimal 15 would be expressed as 0F using the 'X2' format.

Try this: string name = abcdef; byte[] dec = new byte[name.Length]; string[] hex = new string[name.Length]; dec = Encoding.ASCII.GetBytes(name); for(int i = 0; i { hex[i] = dec[i].ToString(X2); } foreach(string h in hex) { Console.Write({0}  h); }
