结果是不包含适合于入口点的静态mian? 怎么改

--------------------编程问答-------------------- 没有static main()函数? --------------------编程问答--------------------
引用 1 楼 xiaogug01 的回复:
没有static main()函数?

应该就是楼上所说的. --------------------编程问答-------------------- public static void Main()  
{}
新建个cs文件,通过main方法调用 --------------------编程问答-------------------- 高手帮我直接改在代码上好吗~刚学不久,自己改老出错。。。 --------------------编程问答-------------------- 是Main函数,不是mian函数,主函数名写错了 --------------------编程问答-------------------- 顶顶顶顶顶  --------------------编程问答-------------------- 把下面的Main()函数的内容改成你调用实例方法的代码就行了
