用C#打印1-1000以内所有质数,每10个一行

用C#打印1-1000以内所有质数,每10个一行

static void Main(string[] args)
        {
            int count = 0;
            for (int i = 2; i < 1001; i++)
            {
                if (IsPrime(i))
                {
                    if ((count %10)==0)
                    {
                        Console.WriteLine();
                    }
                    count++;
                    Console.Write("{0} ", i);
                }
            }
            Console.ReadKey(true);
        }

        static bool IsPrime(int num)
        {
            for (int i = 2; i < num; i++)
            {
                if ((num %i)==0)
                {
                    return false;
                }
            }
            return true;
        }
    }追问能不能简单点说明下意思追答         static void Main(string[] args)
        {
            //记录质数的数目
            int count = 0;
            //最小的质数是2，判断2~1000中的数哪些是质数
            for (int i = 2; i < 1001; i++)
            {
                if (IsPrime(i))
                {
                    //质数数量加一
                    count++;
                    //如果是质数，则输出结果
                    Console.Write(i);
                    //判断是否为第十个
                    if ((count %10)==0)
                    {
                        //是第十个，换行
                        Console.WriteLine();
                    }else{
                        //不是第十个，输出制表符，
                        Console.Write(' ');//   是制表符，控制输出位置的
                    }
                }
            }
            //等待按键，然后结束程序
            Console.ReadKey(true);
        }
