方法一：利用WebRequest，WebResponse 类


        try
        {
            WebRequest wreq = WebRequest.Create
                (
                    "http://www.baidu.com/img/bdlogo.png"
                );

            HttpWebResponse wresp = (HttpWebResponse)wreq.GetResponse();

            Stream s = wresp.GetResponseStream();

            System.Drawing.Image img;

            img = System.Drawing.Image.FromStream(s);

            // 保存 //
            img.Save("C:\\tmpfiles\\aa.png"); 
        }
        catch (Exception err)
        {
            Response.Write(err.Message);
        }

方法二：利用 WebClient 类


        try
        {
            // 利用 WebClient 类
            WebClient my = new WebClient();

            byte[] mybyte;

            mybyte = my.DownloadData("http://www.baidu.com/img/bdlogo.png");

            MemoryStream ms = new MemoryStream(mybyte);

            System.Drawing.Image img = System.Drawing.Image.FromStream(ms);

            // 保存 //
            img.Save("C:\\tmpfiles\\aa1.png");
        }
        catch (Exception err)
        {
            Response.Write(err.Message);
        }
