我们决定来模拟“八神”的最简单一招： 暗杀炎（就是从地上放把火过去），如果“八神”在左侧，其键盘操作为：：↓↘→＋A或C。就是上图中的SDU或SDJ按键。以SDJ为例子，在模拟这个键盘时要非常细心才行，我一开始这样模拟：

m_IoSys.KeyPress(WinIoSys.Key.VK_S);
Thread.Sleep(200);
m_IoSys.KeyPress(WinIoSys.Key.VK_D);
Thread.Sleep(200);
m_IoSys.KeyPress(WinIoSys.Key.VK_J,200);

结果没有成功。仔细研究了一下，其实我们按SDJ按键的时候，是先将S 按下，再将D键按下，然后弹起S键，再弹起D键，最后再按下J键的。那么真正的过程应该这样写：

m_IoSys.KeyDown(WinIoSys.Key.VK_S);
Thread.Sleep(100);
m_IoSys.KeyDown(WinIoSys.Key.VK_D);
Thread.Sleep(100);
m_IoSys.KeyUp(WinIoSys.Key.VK_S);
Thread.Sleep(100);
m_IoSys.KeyUp(WinIoSys.Key.VK_D);
Thread.Sleep(10); //这个地方不能间隔太大，太大就整个动作连不起来了。
m_IoSys.KeyPress(WinIoSys.Key.VK_J, 200);

经过测试，成功模拟我们想要的操作。大家可以看到实际的模拟按键效果。
