            Random rand = new Random();//随机生成总人数
            number  = rand.Next(100);

            delNode = p.GetBestPosition(List ,N,  number);

            Console.Write("输出总人数：");
            Console.WriteLine(number);

            Console.Write("跳水的顺序：");
            Console.WriteLine(delNode );
        }
    }
}

加return屁用没有    如果方法类型是LinkedListNode<int>  或者node是ref 获取还有用

嗯嗯。我之前用了out方式传递参数，但是不会如何初始化，怎么改都不行所以才都用int的，倘若用out的话，该如何初始化啊？？？

帮帮忙
