Convert integer to hexadecimal and back again

Question

How can I convert the following?

2934 (integer) to B76 (hex)

Let me explain what I am trying to do. I have User IDs in my database that are stored as integers. Rather than having users reference their IDs I want to let them use the hex value. The main reason is because it's shorter.

So not only do I need to go from integer to hex but I also need to go from hex to integer.

Is there an easy way to do this in C#?

Answer 1

// Store integer 182
int intValue = 182;
// Convert integer 182 as a hex in a string variable
string hexValue = intValue.ToString("X");
// Convert the hex string back to the number
int intAgain = int.Parse(hexValue, System.Globalization.NumberStyles.HexNumber);
