For a hex literal that’s not prefixed you can quite easily convert it using int.Parse in C#:
string hex = "142CBD"; // this returns 1322173 int intValue = int.Parse(hex, System.Globalization.NumberStyles.HexNumber);
But as you’ve probably noticed, most hex literals are prefixed with 0x (e.g. “0x142CBD”) which would throw a FormatException if you try to parse it using the above code.
In order to parse a 0x prefixed hex literal you need to use the Convert.ToInt32(string value, int fromBase) method instead:
string prefixedHex = "0x142CBD"; // this works, and returns 1322173 int intValue = Convert.ToInt32(prefixedHex , 16);
