C# while循环语句

while语句按不同条件执行一个嵌入语句零次或多次。

案例1：

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp15
{
    class Program
    {
        static void Main(string[] args)
        {
            int score = 0;
            bool cacContinue = true;
            while (cacContinue)
            {
                Console.WriteLine("请输入第一个数字：");
                string str1 = Console.ReadLine();
                int x = int.Parse(str1);
                Console.WriteLine("请输入第二个数字：");
                string str2 = Console.ReadLine();
                int y = int.Parse(str2);
                int sum = x + y;
                if (sum == 100)
                {
                    score++;
                    Console.WriteLine("真棒！{0}+{1}={2}",x,y,sum);
                }
                else
                {
                    Console.WriteLine("你输了！{0}+{1}={2}", x, y, sum);
                    cacContinue = false;
                }
            }
            Console.WriteLine("成绩：{0}",score);
            Console.WriteLine("GAME OVER!");
        }
    }
}
