REQ: How To Do Hex Formatting...

[David Elliott]

I am trying to format bytes and characters in a hexadecimal format that is preceeded with Zeros.

I found some information in the help section "Custom Numeric Format Strings" and
"Standard Numeric Format Strings Output Examples" but am unable to get it to work properly.

I can print by using the following code
byte data;

for (int i = 0; i < 30; i++)
{
data = (byte)i;
System.Console.Out.Write("{0:x} ", data);
}

But this only displays
0 1 2 3 4 5 6 7 8 9 a b c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d

I would like
01 02 03 04 05 06 07 08

and eventually use it for characters to display
0001 0002 0003 0004 0005 ...

Any help would be appreciated.

Cheers,
Dave

how about

System.Console.Out.Write(i.ToString("x").PadLeft(5,'0') + " ");

I think you're after:

Console.Write ("{0:x2} ", data);
