对monogame来说很新（确切地说是android的mono），但是通过一些youtube教程，这个过程相当轻松。我正在尝试覆盖一些函数（来自“XNA 库项目”dll），我可以很好地覆盖所有函数。但是，当我尝试覆盖作为参数传入 SpriteBatch 的任何内容时，出现以下错误：
错误 5 'Parkour.Screens.EditorScreen.Draw(Microsoft.Xna.Framework.Graphics.SpriteBatch)': 找不到合适的方法来覆盖 D:\Data\programming 等\comps\TIGsport\XNA\Parkour\Parkour\Parkour\ Screens\EditorScreen.cs 117 30 跑酷安卓
我绝对确定该方法存在，因为 XNA 项目运行良好。Draw 功能也会在 mono for android 项目中自动更正弹出。但奇怪的是，在我收到错误后，它似乎已经从自动更正中消失了。
这是包含要覆盖功能的整个类，这样你们就可以确定没有任何问题。

里面有很多对你们没用的东西，但为了完整起见，我想把它包括在内。
我对另一个具有需要重写的 Draw(SpriteBatch) 函数的类有完全相同的问题。
