这个意思?using System;
using System.Collections.Generic;
using System.Text;namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            Console.WriteLine("123123123123123123");
            while (true)
            {
                switch (Console.ReadKey(true).Key)
                {
                    case ConsoleKey.UpArrow:
                        if(Console.CursorTop!=0) Console.CursorTop--;
                        break;
                    case ConsoleKey.DownArrow:
                        Console.CursorTop++;
                        break;
                    case ConsoleKey.LeftArrow:
                        if (Console.CursorLeft != 0) Console.CursorLeft--;
                        break;
                    case ConsoleKey.RightArrow:
                        Console.CursorLeft++;
                        break;
                }
