is there anything in C# that is equivalent to VB.NET Hex() function that converts from an integer, long, short, byte to a string representing the hex equivalent of that number?

(16).ToString("x") returns "10"

converts to a string representation of 0x10

(29).ToString("x3") returns "01d"

which is left padded to three characters.

Question: Okay, so how does one take an input string in hex notation =
and convert back to integer?

Answer: int i =3D Int32.Parse("34A1E9",NumberStyles.HexNumber);

Note that the NumberStyle specified doesn't parse the leading "0x" =
notation style. If you give it that kind of input string you'll get a =
format exception error.

Just call the Convert.ToString() method. The first parameter is the
number that you want to convert into another base. The second parameter
is the base that you want the number to be converted to, which can be 2,
8, 10, or 16.
