C#mouse_event模拟点击，无法反应怎么解决

Question

  [System.Runtime.InteropServices.DllImport("user32")]
        private static extern int mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);
        //移动鼠标 
        const int MOUSEEVENTF_MOVE = 0x0001;
        //模拟鼠标左键按下 
        const int MOUSEEVENTF_LEFTDOWN = 0x0002;
        //模拟鼠标左键抬起 
        const int MOUSEEVENTF_LEFTUP = 0x0004;
        //模拟鼠标右键按下 
        const int MOUSEEVENTF_RIGHTDOWN = 0x0008;
        //模拟鼠标右键抬起 
        const int MOUSEEVENTF_RIGHTUP = 0x0010;
        //模拟鼠标中键按下 
        const int MOUSEEVENTF_MIDDLEDOWN = 0x0020;
        //模拟鼠标中键抬起 
        const int MOUSEEVENTF_MIDDLEUP = 0x0040;
        //标示是否采用绝对坐标 
        const int MOUSEEVENTF_ABSOLUTE = 0x8000;

        [DllImport("user32.dll", EntryPoint = "FindWindow")]
        private extern static IntPtr FindWindow(string lpClassName, string lpWindowName);
        //
        [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true)]
        public static extern int ShowWindow(IntPtr hwnd, int nCmdShow);



        [DllImport("USER32.DLL")]
        public static extern bool SetForegroundWindow(IntPtr hWnd);


        //keybd_event、SendMessage
        private void button1_Click(object sender, EventArgs e)
        {


            IntPtr hwnd = FindWindow(null, "拼多多工作台");
            if (hwnd != IntPtr.Zero)
            {
                //MessageBox.Show(hwnd+"找到-拼多多工作台");
                //SetForegroundWindow(hwnd);
            }
            else
            {
                MessageBox.Show("没有找到拼多多工作台");
            }

            mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE, 335*65536/1920, 135*65536/1080, 0, 0);

            SetForegroundWindow(hwnd);
            Thread.Sleep(1000);
            mouse_event(MOUSEEVENTF_LEFTDOWN , 0, 0, 0, 0);
            Thread.Sleep(2000);
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

        }

注意是 拼多多工作后台，模拟点击这个没有反应，鼠标有移动，对准了这个➕

这个需要怎么解决，希望大神看一下，指导一下

试一下这样

mouse_event(MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 335 * 65536 / 1920, 135 * 65536 / 1080, 0, 0);
