c# 改键-之魔兽改键（Hook）
玩过dota的人都知道这游戏要用到一个辅助软件，即改键的软件，由于dota这款游戏的快捷键众多且杂乱无章，所以就需要一款改键的软件把那些快捷键改成我们顺手的，比如我们可以把P改成Q，把B改成W，把C改成E，这样一来QWE是一排紧挨着的按键那么我们操作dota这款游戏起来是不是很顺手了呢，好，说完改键软件的作用下面正题
不用我说大家也都知道改键用到的就是Hook，关于hook的代码网上不是一般的多，在这里就不说了，说了我也是借鉴别人的等于copy了就不好看了，除了钩子hook那么剩下的就很简单了，我不过是七凑八凑组成个改键的软件而已，那我为什么还要写它呢，是因为网上关于改键的程序例子少之又少，我在这里给那些想搜索这方面内容的人提供一些思路，懒得一句一句的解释了，直接贴代码付工程比什么都强
对了，先来张程序的图片吧
前两张图片是N年前写的，代码也找不到了，最近想总结一下又写了一个，写了个大概，小功能尚未完善，正式第三个，写此程序需要三个数组，一个数组保存textbox，第二个数组保存输入的按键的键码值（用于界面填写规则，判断按键是否有重复或者有冲突），第三个数组也是保存按键的键码值，但是与第二个数组不同，它保存的键码值用于钩子改键的并不是用于检查填写的改键是否有冲突的。我为了简单方便并没有采用3个数组，只设了一个二维数组，另两个数组不过把其值添加进textbox的属性里了，前面说3个不过是为了好理解，OK贴代码
