            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;
            Stream stream = request.GetRequestStream();
            stream.Write(data, 0, data.Length);
            stream.Close();
            WebResponse response = request.GetResponse();
            stream = response.GetResponseStream();
            StreamReader sr = new StreamReader(stream);
            string source_code = sr.ReadToEnd();

答案是：将成功登录后的标头响应中生成的set-cookies添加到新请求中。

request.Headers.Add("cookie", "value");
