1获得当前屏幕中鼠标的位置

            int i = MousePosition.X;
            int j = MousePosition.Y;

2移动鼠标

首先引入dll

 [System.Runtime.InteropServices.DllImport("user32")]
        private static extern int mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);
        const int MOUSEEVENTF_MOVE = 0x0001;
        const int MOUSEEVENTF_LEFTDOWN = 0x0002;
        const int MOUSEEVENTF_LEFTUP = 0x0004;
        const int MOUSEEVENTF_RIGHTDOWN = 0x0008;
        const int MOUSEEVENTF_RIGHTUP = 0x0010;
        const int MOUSEEVENTF_MIDDLEDOWN = 0x0020;
        const int MOUSEEVENTF_MIDDLEUP = 0x0040;
        const int MOUSEEVENTF_ABSOLUTE = 0x8000; 

然后调用

mouse_event(MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE, 38843, 53702, 0, 0);

说明，有 | MOUSEEVENTF_ABSOLUTE表示绝对位置，好用

绝对位置计算，x= 屏幕鼠标坐标mouseposition.x*65535/1920（这是显示器分辨率宽）

绝对位置y=mouseposition.y*65535/1080屏幕高

3鼠标点击模拟
            mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);
