C# 操作地址 从内存中读取写入数据(初级)

本示例以植物大战僵尸为例, 实现功能为 每1秒让阳光刷新为 9999.本示例使用的游戏版本为 [植物大战僵尸2010年度版], 使用的辅助查看内存地址的工具是  ce.

由于每次启动游戏, 游戏中阳光地址都是变的, 唯一不变的基址1, 我们要通过ce工具找到基址1的地址, 可以算出阳光的地址.

基址2的地址 = 基址1中的值 + 偏移1;

阳光的的地址 = 基址2中的值 + 偏移2;

以下为简单示例:  窗口界面一个按钮 和 一个定时器

下面增加了一个刷新金币的示例 (注意, 金币值是界面的金币输 除以 10 , 我们刷100 在界面里面显示为1000)
