        private static List<int> ComputerEightDiagrams(List<int> numbs)
        {
            List<int> dias = new List<int>();

            for (int i = 0; i < numbs.Count; i++)
            {
                if (i != numbs.Count - 1)
                {
                    var m = numbs[i] % 8;

                    if (m == 0) m = 8;

                    dias.Add(m);

                }
                else
                {
                    var n = numbs[i] % 6;

                    if (n == 0) n = 6;

                    dias.Add(n);
                }
            }
            return dias;
        }

根据用户的输入确定是哪一卦，哪一爻。

下面的代码是如何在控制台打印八卦图：

        private static void Print(List<int> diagrams)
        {
            //存储
            string[] keys = { "111", "011", "101", "001", "110", "010", "100", "000" };

            var up = diagrams[1];
            var down = diagrams[0];

            var upStr = keys[up - 1];
            var downStr = keys[down - 1];

            n = 0;
            PrintYao(upStr.ToCharArray(), diagrams[2]);
            PrintYao(downStr.ToCharArray(), diagrams[2]);

            Console.ResetColor();
        }

        private static int n = 0;
        private static void PrintYao(char[] chars, int yao)
        {
            bool isYao=false;

            foreach (var item in chars)
            {
                n++;

                Console.WriteLine("");

                isYao = n == 6 - yao + 1;

                if (item == '1')
                {
                    Console.BackgroundColor =isYao? ConsoleColor.Yellow:ConsoleColor.Blue;
                    Console.WriteLine("            ");
                }
                else if (item == '0')
                {
                    Console.BackgroundColor = isYao ? ConsoleColor.Yellow : ConsoleColor.DarkRed;
                    
                    var color = Console.BackgroundColor;

                    Console.Write("     ");

                    Console.ResetColor();
                    Console.Write("  ");

                    Console.BackgroundColor = color;
                    Console.Write("     ");
                    Console.Write("
");
                }
            }
        }

diagrams，存储了上卦和下卦的顺序，其中keys数组中存储了八卦的爻信息，1：阳爻，0：阴爻。比如 111代表乾卦。
此程序运行效果如下：
