一个C#写的模拟键盘输入的例子
如题,模拟键盘输入有很多方法,比如sendkey,keybd_event以及postmessage等,但大多游戏都对这些方法进行了屏蔽,特别是用DIRECTX写的游戏直接绕过操作系统直接读取键盘输入,因此上述三种方法都不好用,在网上查到使用WINIO方法可直接模拟键盘输入,因此自己试了一下,网上介绍的方法很少有c#写的,而且写出来的也无法直接使用,我把网上介绍的C#方法同其他语言写的进行了比较,终于找到了问题所在.调试终于通过了.
winio可以到这里去下载：http://www.internals.com/
下载解压后把“Binaries”文件夹下的文件拷贝入程序目录下。
//程序界面很简单,就是含一个"button"窗体程序。
程序思路如下：
1.找到桌面上的需要模拟键盘输入的窗口，本程序中的是“铁钩船长”这一款游戏，窗口名称为： "MAME: Hook (World) [hook]"
2.使被找到窗口成为输入焦点
3.模拟键盘输入
