由于本人学习时间不长，到现在为止只是学到了I/O操作方面，想编写一个控制台小游戏，类似简易版的魔塔。前期从网上搜了很多资料想搞清楚控制台游戏如何控制人物的移动，但是搜了很久，找到的都是一些超出自己目前学习进度的知识点，个人感觉对于新手来说有一定的难度，最后通过我的不断思索，想到了一种很简易的方法，特别适合目前自己的水平。
在C#中通过Console.ReadKey()是能读取用户输入的，所以现在问题就是在地图中人物的移动如何与用户的输入联动起来。下面的代码详细说明了自己的思路
首先创建一个二维数组，提前设计好规则，每个数字所对应的涵义。这里1代表墙，2代表英雄的初始位置，3代表怪物，4代表出口
//用数组绘制地图
int[,] map = new int[20, 40]
{
{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1 },
{1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,3,0,0,0,0,0,0,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,0,0,0,0,0,0,0,1,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,0,0,0,1,1,1,1,1,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,3,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,3,0,0,0,0,0,0,0,1 },
{1,0,0,0,3,0,0,0,0,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,1,1,1,1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },

{1,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1 },
{1,0,0,0,0,0,1,0,0,0,0,0,0,0,0,0,1,1,1,1,1,1,0,0,0,0,0,0,0,3,0,0,0,0,0,0,0,0,0,1 },

}; //英雄初始位置坐标
int aa = 19, bb = 1;然后循环执行如下代码
while (true)

}这样的话通过不停擦除二维数组再重新绘制二维数组，人物也能实现不停的移动。
当然肯定还有很多更好的方法能实现人物的移动，但是以自己目前的水平感觉这是最适合的方式。
