Answer 1

给你个源代码，
private Image GetCodeImage(string path)
        {
            HttpWebRequest request = WebRequest.Create(string.Format("{0}{1}", URI, path)) as HttpWebRequest;
            HttpWebResponse response = null;
            Stream stream = null;
            Image result = null;            request.Method = "GET";
            request.Referer = string.Format("{0}main.aspx", URI);
            request.UserAgent = "MSIE 6.0";
            request.CookieContainer = cookie;            try
            {
                response = request.GetResponse() as HttpWebResponse;
                stream = response.GetResponseStream();
                cookie.Add(response.Cookies);
                result = Image.FromStream(stream);
                stream.Close();
            }
            catch (Exception e) { throw new Exception(e.Message + "," + e.TargetSite + "," + e.InnerException); }
            finally
            {
                if (response != null) response.Close();
            }
            return result;
        }

Answer 2

简单的,用webbroswer+ HTML
复杂的,有httpRequest+Cookie

Answer 3

httpRequest+Cookie还没用过..
去搜搜资料去

Answer 4

用这种方法,最好先下载个抓包程序,用来看看IE和Server之间数据交换的格式和cookie/session之间的传值过程.然后直接调用验证码的URL,并把cookie值传过去,拿到图片.

Answer 5

 System.Net.WebClient.DownloadData(验证码图片网址)返回一个byte[]
用这个byte[]构建一个MemoryStream
用Image.FromStream载入这个MemoryStream
设置PictureBox.Image=这个img就是了
