偶尔做下基础题

将1-100之间的能被7整除的书输出

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            for (int i = 1; i < 101;i++)
                if(i%7==0)    
                    Console.WriteLine(i +" ");
            Console.ReadKey();
        }
    }
}

编辑电视歌手大奖赛评分程序，美味评委的打分从键盘给入，直到输入-1，去掉一个最高分，再去掉一个最低分，求评委给出的最后得分（设至少有两位一下个的评委）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            List<double> _lCount = new List<double>();
            double _inNum;
            double sum = 0;
            do
            {
                Console.WriteLine("input :");
                _inNum = double.Parse(Console.ReadLine());
                if (_inNum == -1)
                    break;
                _lCount.Add(_inNum);
            } while (true);
            _lCount.Sort();
            _lCount.RemoveAt(0);
            _lCount.RemoveAt(_lCount.Count - 1);
            sum = _lCount.Sum(); //.NET Framework 3.5
            Console.WriteLine("end :" + sum);
            Console.ReadKey();
        }
    }
}
