接收字符串

            // 接收返回的页面
            HttpWebResponse response = request.GetResponse() as HttpWebResponse;
            System.IO.Stream responseStream = response.GetResponseStream();
            System.IO.StreamReader reader = new System.IO.StreamReader(responseStream, Encoding.Default);
            string srcString = reader.ReadToEnd();

生成图片

            CookieContainer cookieContainer = new CookieContainer();
            HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
            request.Method = "POST";
            request.KeepAlive = false;
            request.CookieContainer = cookieContainer;

            // 接收返回的页面
            HttpWebResponse response = request.GetResponse() as HttpWebResponse;
            Stream stream = response.GetResponseStream();

            string path = "D:\\father.jpg";
            FileStream os = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write); 
            byte[]   buff=new   byte[512]; 
            int   c=0; 
            while((c=stream.Read(buff,0,512))> 0) 
            { 
                os.Write(buff,0,c); 
            } 
            os.Close(); 
            stream.Close();
