Convert From HEX

[MDB]

Hello all, I am not sure if I am using the correct verbiage however, I need
to convert  to 02. I believe  is a hex string? And I need to know the
into value but I need the 02 value not just 2.

MDB,

If you have any character in a char variable, you can just cast that to
an int, and then use the ToString method to format the output, like so:

// Convert the char c to a hex string.
string hexString = ((int) c).ToString("x");

However, this will not let you know if you need two characters or not.
You can then just tack the leading zero on if it is not there.

// If the length is less than what is required, then tack the leading
// zeros on.
if (hexString.Length < 2)
{
// Tack the leading zeros on.
hexString = new string('0', 2 - hexString.Length) + hexString;
}

I've coded it this way so you could replace 2 with a constant, depending
on whether or not your string length changes.

Hope this helps.
