C#内存操作

原文:[转]C#内存操作

最近闲来无事发现周围的朋友都在玩《植物大战僵尸》的游戏！于是动了制作这游戏工具的念头！虽然在网上同类工具很多 但是用C#写的我几乎看不到！所以我想用C#写一个！
  首先用CE或者OD或者其他反汇编工具找出游戏的内存基址！
  游戏内存基址：base = 0x006A9EC0
  游戏阳光地址：[base+0x768]+0x5560
  游戏金钱地址：[base+0x82C]+0x28
  游戏关卡地址：[base+0x82C]+0x24 //关卡如：A-B 实际值为：（A-1）×10＋B
至于如何获取这些地址不在我们这论坛研究的范围中！
对了我是用工具vs2008编写的！
新建窗体：
