1 //0成功  1失败  2异常  3正常  4上线  5下线 
2             while (true)
3             {
4                 Console.Write("请输入a的值:");
5                 int a = Convert.ToInt32(Console.ReadLine());
6                 Console.WriteLine(a == 0 ? "成功" : (a == 1 ? "失败" : (a == 2 ? "异常" : (a == 3 ? "正常" : (a == 4 ? "上线" : (a == 5 ? "下线" : "未知"))))));
