Answer 1

弄个字典,从A-G映射到具体的症状
然后就可以用linq把整个字符串替换成实际的症状列表了

Answer 2

这么多if，用switch

Answer 3

其实还是可以用Contains
  if (s.Contains("A"))
                ss += "1";
            if (s.Contains("B"))
                ss += "2";
            if (s.Contains("C"))
                ss += "3";

Answer 4

Dictionary<T1,T2>你会发现神奇的东西
