获取网页图片

public Bitmap Get_img() { Bitmap img = null; HttpWebRequest req; HttpWebResponse res = null; try { System.Uri httpUrl = new System.Uri("http://xxx.com/xxx.png "); req = (HttpWebRequest)(WebRequest.Create(httpUrl)); req.Timeout = 180000; //设置超时值10秒 req.UserAgent = "XXXXX"; req.Accept = "XXXXXX"; req.Method = "GET"; res = (HttpWebResponse)(req.GetResponse()); img = new Bitmap(res.GetResponseStream());//获取图片流 img.Save(@"E:/" + DateTime.Now.ToFileTime().ToString() + ".png");//随机名 } catch (Exception ex) { string aa= ex.Message; } finally { res.Close(); } return img; }

直接将图片流 付给bitmap

 

Bitmap img = new Bitmap(res.GetResponseStream());
