C# 如何从txt文件中拖动2d级别数组

我正在努力改进我在本教程中完成的这个塔防gtame。我现在希望从文本文件中加载这些级别，但不太确定如何使用streamreader实现这一点，有什么提示吗？这是我的level类的源代码

public class Level
{
    protected int temperature;
    protected int levelNo;
    private Queue<Vector2> waypoints = new Queue<Vector2>();
    public Queue<Vector2> Waypoints
    {
        get
        {
            return waypoints;
        }
    }

    int[,] map = new int[,]
