代码如下:
using System; class Switch_Test { static void Main() { Console.WriteLine("box sizes: 1=Small 5=Medium 10=Large"); Console.Write("请选择: "); string s = Console.ReadLine(); int n = int.Parse(s); int cost = 0;//初始化数据 switch (n) { case 1: cost += 1; break; case 5: cost += 5; goto case 1; case 10: cost += 10; goto case 1; default: Console.WriteLine("无效的输入. 请选择1, 5, or 10."); break; } Console.WriteLine("Thank you !你的花费={0}", cost); } }
