asp.net 截屏 截取web页面

 1 using System.Drawing;
 2 
 3 //调用浏览器打开页面
 4 System.Diagnostics.Process.Start("IEXPLORE.EXE", "http://localhost:56/Spacxxe.html");
 5 //停止3秒,等页面打开
 6 System.Threading.Thread.Sleep(3000);
 7 
 8 //截屏
 9 //创建并设置画布大小
10 System.Drawing.Image templateImage = new System.Drawing.Bitmap(1040, 700);
11 System.Drawing.Graphics templateG = System.Drawing.Graphics.FromImage(templateImage);
12 
13 //new Point(200, 100)位于源(屏幕)左上角的x,y坐标
14 //new Point(0, 0)图片位于画布左上角的x,y坐标
15 //new Size(1440, 900)所截屏幕的大小
16 templateG.CopyFromScreen(new Point(200, 100), new Point(0, 0), new Size(1000, 900), CopyPixelOperation.MergeCopy);
17 
18 //关闭ie
19 System.Diagnostics.Process[] pro = System.Diagnostics.Process.GetProcessesByName("IEXPLORE");
20 foreach (System.Diagnostics.Process ps in pro)
21 {
22     ps.Kill();
23 }
24 
25 //存图片
26 templateImage.Save(@"E:\TEST\" + imgname + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

截图过程,是通过aps.net 页面调用ie浏览器进程打开页面,并且调用CopyFromScreen来截屏并保存。
