STRING TO HEX how to add in a vector ob bytes?

Question

I have the following code:

string s =   "2563MNBJP89256666666685755854";
            Byte[] bytes = encoding.GetBytes(s);
            string hex = "";
            foreach (byte b in bytes)
            {
                int c=b;
                hex += String.Format("{0:x2}", (uint)System.Convert.ToUInt32(c.ToString()));
            }

It prints the hex values . How can I add it in a vector ob bytes like this?

new byte [0x32,0x35..]

In hex I have : 323536....and so on. The next step is to add then in a byte[] vector in the following format 0x32,0x35..and so on; How to do this?

THX

do you mean an array of bytes? do you mean base64? do you mean another string of Hexidecimal numeral characheters? — Jodrell, May 18 '11 at 08:20

Isn't bytes already the list of bytes you want?

how to chech that? how to print the bytes values? – daniel May 18 '11 at 08:47
No it's not the same. The values are different:). – daniel May 18 '11 at 08:48
in s the results are: 50,53,54.. and in hex: 32,35,36 and so on – daniel May 18 '11 at 08:49
in s the results are in char! and in hex the results are in hexa values. – daniel May 18 '11 at 08:52
@daniel: Those are the same numbers. The first list is just represented in decimal while the second one is in hexadecimal. – Matti Virkkunen May 18 '11 at 08:54
I want the results in hexadecimal. How to convert them? – daniel May 18 '11 at 08:56
@daniel: Isn't that what your loop is doing? Converting them? I think you're confused as to what a number is. And judging by the comments on your first post you, it's not going to be worth my time to explain to you what a number is. – Matti Virkkunen May 18 '11 at 08:57
I am doing an encryption:). The result is different if i send encoding.getBytes(string) or if i send new byte[]{0x32,0x35..}. Where string is the string I want to have in hexadecimal – daniel May 18 '11 at 09:01

it's not the same thing. i've tested it:) – daniel May 18 '11 at 07:45
What is not the same? You get the byte values associated with each character. – Botz3000 May 18 '11 at 07:49

For C# you could try

System.Text.ASCIIEncoding  encoding=new System.Text.ASCIIEncoding();
Byte[] bytes = encoding.GetBytes(strVar);//strVar is the string variable
