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#?

// 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);

HINT (from the comments):
Use .ToString("X4")
to get exactly 4 digits with leading 0, or .ToString("x4")
for lowercase hex numbers (likewise for more digits).
