SendInput鼠标单击X / Y

Question

我正在尝试使用C＃构建clickbot，但是我遇到了一些问题。

单击有效，但它会继续单击光标当前所在的位置，而不是x和y位置。

我使用以下代码并插入了x和y位置。

        mouseDownInput.mkhi.mi.dx = 1809;
        mouseDownInput.mkhi.mi.dy = 93;

我也尝试添加

            mouseDownInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTDOWN | MouseEventFlags.MOUSEEVENTF_ABSOLUTE;

How to programmatically mouse move,click,right click and keypress, etc. in winform and wpf?
