Attempted conversion of '0x8F8C' failed.

Answer 2

You need to drop the "0x" prefix. Please see this blog entry

Answer 3

Get rid of the leading "0x" in the string you're trying to parse.

Answer 4

// stupid but effective way to improve the parsing
char[] _trim_hex = new char[] {'0','x'};
int temp;

if (int.TryParse(value.TrimStart(_trim_hex), NumberStyles.HexNumber, null, out temp))
{
    // temp is good
}
