贪吃蛇StringBuilder 和 定时器

ConsoleKeyInfo info = Console.ReadKey();
            while (true)
            {
                if (info.Key == ConsoleKey.UpArrow)//只能输入一次但会保留这种状态
                {
                    Console.Write("sdfdsg");
                }
            }
        }

while (true)
            {
                ConsoleKeyInfo info = Console.ReadKey();//不输入就无法执行循环
                if (info.Key == ConsoleKey.UpArrow)
                {
                    Console.Write("sdfdsg");
                }
            }
        }

class Food :RANDOM
    {
        public void food()
        {
            random();
        }
        public void theout(object source, System.Timers.ElapsedEventArgs e)
        {
            Console.Write("sdfs");
        } 
    }
主函数
System.Timers.Timer t = new Timer(3000);//3秒执行一次
            Food f = new Food();
            t.Enabled = true;
            t.Elapsed += f.theout;
            t.AutoReset = true;
            Console.ReadKey();
