刚刚接触c#感觉要记好多东西的样子。

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace MyFirstAPP{    class Program    {        static void Main(string[] args)        {            int Cnt = 0;            string shape = "+-*";            Console.WriteLine("请输入你的大名？");            string name;            name = Console.ReadLine();            Console.WriteLine("您好，{0}",name);                          Console.WriteLine("请输入第一个整数");            int Num1;            Num1 = Convert.ToInt32(Console.ReadLine());            Console.WriteLine("请输入第二个整数");            int Num2;            Num2 = Convert.ToInt32(Console.ReadLine());            for (int i = 0; i < 3; ++i)            {                Console.WriteLine("{0} {1} {2}=?", Num1,shape[i], Num2);                int Date;                Date = Convert.ToInt32(Console.ReadLine());                if ((i==0&&Date == Num1 + Num2)||(i==1&&Date==Num1-Num2)||(i==2&&Date==Num1*Num2))                {                    Console.WriteLine("回答正确！"); Cnt++;                }                else Console.WriteLine("回答错误！");            }            Console.WriteLine("你答对了{0}",Cnt);        }    }}
