GDI+ 、directx、dxgi   => 我认为这就是一个东西，因为运行起来，硬件消耗特别低，直接代码：

        private void button1_Click(object sender, EventArgs e)
        {
            
            System.Threading.Thread thread = new System.Threading.Thread(ThreadMethod);
            thread.Start();
        }

        private void ThreadMethod()
        {
            Image bt = new System.Drawing.Bitmap(c.Bounds.Width, c.Bounds.Height);
                Graphics g = Graphics.FromImage(bt);
            try
            {
                
                for (int a = 0; a < 3000; a++)
                {
                    g.CopyFromScreen(0, 0, 0, 0, c.Bounds.Size, CopyPixelOperation.SourceCopy);
                    // var i = copyscreen();
                    //pictureBox1.Image = bt;
                    Console.WriteLine(1);
                    System.Threading.Thread.Sleep(10);
                }
                g.Dispose();
            }
            catch (Exception _e)
            {
                g.Dispose();
                System.Threading.Thread.CurrentThread.Abort();

            }
        }

        Image copyscreen()
        {
            Image bt = new System.Drawing.Bitmap(c.Bounds.Width, c.Bounds.Height);
            Graphics g = Graphics.FromImage(bt);
            g.CopyFromScreen(0, 0, 0, 0, c.Bounds.Size, CopyPixelOperation.SourceCopy);
            g.Save();
            g.Dispose();
            
            
            return bt;
        }
