奇进偶不进解释

代码

public class IsopsephyNumber
    {
        private double value = 0.0;
        private bool isFlag = false;
        /// <summary>
        /// 奇进偶不进
        /// </summary>
        public void JiNumInAndOuNunOut()
        {
            while (true)
            {
                string numberStr = Console.ReadLine();
                if (!string.IsNullOrEmpty(numberStr) && numberStr.Trim().ToLower().Equals("exit"))
                {
                    break;
                }
                JudgeNumber(numberStr, out value, out isFlag);
                if (isFlag)
                {
                    double result = Math.Round(value, 3, MidpointRounding.ToEven);
                    Console.WriteLine("结果：" + result + ":" + value);
                }
            }
        }

        private static void JudgeNumber(string numberStr, out double value, out bool isFlag)
        {
            value = 0.0;
            isFlag = double.TryParse(numberStr, out value);
        }
    }
