(错误    1    程序“E:\ConsoleApplication1\ConsoleApplication1\obj\Debug\ConsoleApplication1.exe”不包含适合于入口点的静态“Main”方法    ConsoleApplication1
)

为什么？？？？？？？？知道的，给我点答案，谢谢！！！！

大哥，你这算法求素数是要从3开始取的。。。

using System;
using System.Collections.Generic;

namespace test2
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            int m, k, n = 0;
            bool flag;
            for (m = 3; m < 100; m += 2)
            {
                flag = true;
                for (k = 2; k <= Math.Sqrt(m); k++)
                    if (m % k == 0)
                    {
                        flag = false;
                        break;
                    }
                if(flag)
                {
                    Console.Write(m.ToString()+" ");
                    if (++n % 10 == 0)
                        Console.Write("\n");
                }

            }
            Console.ReadKey();
        }
    }
}

Ls是高手。

VS生成的函数的main不是你那样的吧

public static void Main(string[] args)

大写 ，呵呵
