这不能用,那不能用的,你干脆写1000条print语句吧!

Answer 2

using System;
using System.Collections.Generic;
using System.Text;namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            Add(1);
        }        public static void Add(int i)
        {
            Console.WriteLine(i++);
            Add(i);            
        }
    }
}没有if不知道你怎么停止

Answer 3

using System;
using System.Collections.Generic;
using System.Text;namespace ConsoleApplication2
{
    class Program
    {
        static void Main(string[] args)
        {
            Add(1);
        }        public static void Add(int i)
        {
            Console.WriteLine(i++);
            if (i == 1001)//到1000的时候停止
                Console.ReadLine();
            Add(i);            
        }
    }
}

Answer 4

using System;
using System.Collections.Generic;

        {
            Add(1);
        }        public static void Add(int i)
        {
            Console.WriteLine(i++);
            switch (i)
            {
                case 1001:
                    break;
               default:
                    Add(i);
                    break;
            }
        }

using System;
using System.Collections.Generic;
using System.Text;namespace ConsoleApplication1
{
    class Program
    {
        private static int _i = 0;        public static  int I
        {
            get { return _i;  }
            set 
            { 
                _i = value;
                Console.WriteLine(_i);
                switch (_i)
                {
                    case 1000:
                        break;
                    default:
                        I++;
                        break;
                }
            }
        }        static void Main(string[] args)
        {
            I++;
        }
