各位大神，这个软件的算法知道，怎么来计算这个结果？注册码是字母来的!比如 软件码是4823-AB258-133EDB2，怎么去计算结果

private int RegCodeeque(string InputCode)
{
    int num = 0;
    string serialNumberD = this.getSerialNumberD();
    string serialNumber = this.getSerialNumber();
    string right = Conversion.Hex(Math.Round(Conversions.ToDouble(serialNumberD) / 6.2 + 656.0));
    string right2 = Conversion.Hex(Math.Round((Conversions.ToDouble(serialNumber) + 6622.0) / 3.0 + 12.0, 0));
    DateTime dateTime = Conversions.ToDate(Strings.Format(DateAndTime.Now.Date, "yyyy/MM/dd"));
    string[] array = Strings.Split(InputCode, "-", -1, CompareMethod.Binary);
    bool flag = array.Length != 3;
    checked
    {
        int result;
        if (flag)
        {
            result = 0;
        }
        else
        {
            flag = (Operators.CompareString(array[0], right, false) != 0);
            if (flag)
            {
                result = num;
            }
            else
            {
                flag = (Operators.CompareString(array[1], right2, false) != 0);
                if (flag)
                {
                    result = num;
                }
                else
                {
                    int num2 = (int)Math.Round(unchecked((double)Conversions.ToLong("&H" + array[2]) / 4.0 + 13.0));
                    DateTime value = Conversions.ToDate(Strings.Format(num2, "0000-00-00"));
                    int num3 = Math.Abs((int)Math.Round(dateTime.Subtract(value).TotalDays));
                    flag = (num3 == 297);
                    if (flag)
                    {
                        Interaction.MsgBox("程序就快到期，请联系程序作者!", MsgBoxStyle.OkOnly, null);
                        num = 30;
                    }
                    else
                    {
                        flag = (num3 < 300);
                        if (!flag)
                        {
                            return num;
                        }
                        num = 30;
                    }
                    result = num;
                }
            }
        }
        return result;
    }
}

谢谢大神指教
