无法访问已处置的对象。对象名称：“ Icon”，当我正在做的是生成图块精灵时，MonoGame中会随机发生错误

Question

我是第一次学习MonoGame，我制作了一个系统，该系统生成地图字典并在玩家附近生成瓦片，并在超出范围时将其删除。

这似乎按预期工作，但是我走了一会儿后出现此错误：

System.ObjectDisposedException：'无法访问已处置的对象。对象名称：“图标”。]]

看似没有图案。它显示在行上：

public Tile(int X, int Y, string Type)
我是面向对象编程的新手，但由于似乎无关，无法理解在线错误的原因。如果需要更多信息，请询问，我将其添加。我将非常感谢您的帮助。

[瓦片精灵：

//##Tile##
    public class Tile : Game
    {
        //##Default Varibles##
        public Vector2 Scale;
        public Vector2 Position;
        public Rectangle Rect;

        //##Initialise##
        public Vector2 GridPosition;
        public Tile(int X, int Y, string Type)
        {
            Console.WriteLine("StackTrace: '{0}'", Environment.StackTrace);

            //Position
            GridPosition = new Vector2(X, Y);
            Position = new Vector2(MainGame.instance.Graphics.PreferredBackBufferWidth / 2 - MainGame.instance.AssetManager.TileTextureList[0].Width / 2 + X * 64, MainGame.instance.Graphics.PreferredBackBufferHeight / 2 - MainGame.instance.AssetManager.TileTextureList[0].Height / 2 + Y * 64);

            //Rect
            Rect = new Rectangle((int)Position.X, (int)Position.Y, MainGame.instance.AssetManager.TileTextureList[0].Width, MainGame.instance.AssetManager.TileTextureList[0].Height);
        }

        //##EveryFrame##
        public void Update()
        {
            //Function Calls


            //Update Rectangle
            Rect.Location = new Point((int)Position.X, (int)Position.Y);
        }

        //##Draw##
        public void Draw()
        {
            MainGame.instance.MainLayer.Draw(texture: MainGame.instance.AssetManager.TileTextureList[0], position: Position, color: Color.White);
        }
    }
我认为堆栈跟踪：

如果我不走一会儿，它不会崩溃。

似乎您正在创建内部game类的多个实例。
