Hi John,

Normaly Jon answers this, I did not see him some days, I try it.

A string is in unicode format, 2Bytes in dotNet programs.

Maybe you do you want to convert an byte array which holds extended ASCII to
a string?
(Which than will be unicode 2Bytes).

In VB there there are two functions for that Chr and ChrW while the last is
advised.

byte[] bs = {0xef, 0xee, 0xaa}
foreach (byte b in bs

System.Console.WriteLine(b.ToString("x"))

John,
In addition to others comments, I would use a StringBuilder to build the
string of hex digits.

Something like:

Dim bytes() As Byte = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14,
15, 16, 17, 18, 19, 20}

Dim sb As New System.Text.StringBuilder(bytes.Length * 2)
For Each b As Byte In bytes
sb.Append(b.ToString("x2"))
Next
Dim s As String = sb.ToString

Hope this helps
Jay

Yup - I've been away.

Hang on though - that's not what he's asking for. He's basically asking
for BitConverter.ToString(byte[]).

He wants to *format* a byte array, not *decode* it.

I knew also that that could be the question, however really sure was I not
from that because "appear" is not "showed". (The old charactersstrings
where in one byte hex format). I take always the answer on what most people
fits first. It was a try what would be the answer to get that sure.
