C#获取网页的验证码，并且显示在 picbox控件上

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://127.0.0.1/pic/Default.aspx"); request.Timeout = 20000; request.ServicePoint.ConnectionLimit = 100; request.ReadWriteTimeout = 30000; request.Method = "GET"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); if (response.StatusCode != HttpStatusCode.OK) return; Stream resStream = response.GetResponseStream(); this.pictureBox1.Image = new Bitmap(resStream);

读取页面返回的字符串，并显示在Lable上

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://10.225.105.18/pic/Default2.aspx"); request.Timeout = 20000; request.ServicePoint.ConnectionLimit = 100; request.ReadWriteTimeout = 30000; request.Method = "GET"; HttpWebResponse response = (HttpWebResponse)request.GetResponse(); if (response.StatusCode != HttpStatusCode.OK) return; StreamReader reader = new StreamReader(response.GetResponseStream()); this.label1.Text = reader.ReadLine();

注：http://127.0.0.1/pic/default.aspx 为你要访问的生成图片注册码的页面
