c#模拟鼠标滚轮向下

我使用以下代码:

private const int MOUSEEVENTF_WHEEL = 0x0800;

public void MouseWheelUp()
{
    mouse_event(MOUSEEVENTF_WHEEL, 0, 0, 120, 0);
}

但是我如何让它向下滚动？

最佳答案

mouse_event function

函数签名:

VOID WINAPI mouse_event(
  _In_ DWORD     dwFlags,
  _In_ DWORD     dx,
  _In_ DWORD     dy,
  _In_ DWORD     dwData,
  _In_ ULONG_PTR dwExtraInfo
);

向下滚动:

mouse_event(MOUSEEVENTF_WHEEL, 0, 0, -120, 0);
