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：

 1         private static void Print(List<int> diagrams)
 2         {
 3             //存储
 4             string[] keys = { "111", "011", "101", "001", "110", "010", "100", "000" };
 5
 6             var up = diagrams[1];
 7             var down = diagrams[0];
 8
 9             var upStr = keys[up - 1];
10             var downStr = keys[down - 1];
11
12             n = 0;
13             PrintYao(upStr.ToCharArray(), diagrams[2]);
14             PrintYao(downStr.ToCharArray(), diagrams[2]);
15
16             Console.ResetColor();
17         }
18
19         private static int n = 0;
20         private static void PrintYao(char[] chars, int yao)
21         {
22             bool isYao=false;
23
24             foreach (var item in chars)
25             {
26                 n++;
27
28                 Console.WriteLine("");
29
30                 isYao = n == 6 - yao + 1;
31
32                 if (item == ‘1‘)
33                 {
34                     Console.BackgroundColor =isYao? ConsoleColor.Yellow:ConsoleColor.Blue;
35                     Console.WriteLine("            ");
36                 }
37                 else if (item == ‘0‘)
38                 {
39                     Console.BackgroundColor = isYao ? ConsoleColor.Yellow : ConsoleColor.DarkRed;
40
41                     var color = Console.BackgroundColor;
42
43                     Console.Write("     ");
44
45                     Console.ResetColor();
46                     Console.Write("  ");
47
48                     Console.BackgroundColor = color;
49                     Console.Write("     ");
50                     Console.Write("\r\n");
51                 }
52             }
53         }

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：
