前言
通过 C# 或 VB.NET，仅需编写少量代码，即可模拟按键事件。
第一节 调用接口
通过调用系统底层 API ，获取或设置指定的按键状态。
获取按键状态
调用 GetAsyncKeyState() 获取指定按键的状态，GetActiveKey() 检索指定范围内的按键状态
合成击键事件
调用 keybd_event() 可合成一次击键事件，通常两次击键事件间需要设定时间间隔
对 DirectInput 有效
调用 MapVirtualKey() 获取指定按键的硬件扫描码，传入 keybd_event() 第二个参数可以对 DirectInput 有效。
第二节 帮助类
实现一系列的静态方法，由此提供不同的模拟按键功能。
