 public void Sleeping()
        {
            Thread.Sleep(5000);
        }
string path = Directory.GetCurrentDirectory();
                string[] lines = System.IO.File.ReadAllLines(path + "\\links.txt");
                string[] lines2 = System.IO.File.ReadAllLines(path + "\\links.txt");

                tableLayoutPanel1.ColumnCount = 10;
                tableLayoutPanel1.RowCount = 10;

                numberofline = 1;
                int colnum = 0;
                int rownum = -1;
                int dummy = 0;
                //numberofline = 0;
                while (true)
                {
                    numberofline = 0;
                    foreach (string line in lines)
                    {
                        if (numberofline > 0)
                        {
                            vlcControl1.SetMedia(line);
                            vlcControl1.Play();
                            Sleeping();
                            vlcControl1.Pause();
                            using (var bmp = new Bitmap(vlcControl1.Width, vlcControl1.Height))
                            {
                                vlcControl1.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
                                bmp.Save(path + "\\tv" + numberofline.ToString() + ".bmp");
                            }
                            vlcControl1.Stop();

                        numberofline = numberofline + 1;

推荐答案

我认为要创建线程来休眠并使布尔循环

i think to create thread to sleep and make boolean to loop

然后睡眠结束，然后失控。我不知道是否工作，明天晚上我会试试

and then sleep finish, then out of loop. i do not know whether work or not, i will try it tomorrow night
