you can see that there is a hexadecimal number below "LINE", is there anyway i can extract it into some list?

like
VALUE = 1C1CBD

NOTE: the file consist more than one of this kind of pattern

and then how can i get the maximum value?

EDIT 1

i see that "5" can be found by using regex "\s\s5" can i use this?

Answer 1

Thank you for your feedback i have been able to complete what i want
here is the code

string[] handle = originalString.Split(new string[] { "\r\n" }, StringSplitOptions.None);
        List<string> hexa = new List<string>();
        for (var a = 1; a <= handle.Count() - 1; a++)
        {
            if (Regex.IsMatch(handle[a], @"^\s\s5"))
            {
                hexa.Add(handle[a + 1]);
            }
        }

        List<int> HexaToInt = new List<int>();
        foreach (string valueHexa in hexa)
        {
            int intHexaValue = int.Parse(valueHexa, System.Globalization.NumberStyles.HexNumber);
            HexaToInt.Add(intHexaValue);
        }

        int maximumHexa = HexaToInt.Max();
        string hexValue = maximumHexa.ToString("X");

it is possible afterall to extract the hexadecimal value from the handle group codes
