C＃如何通过HttpWebRequest调用具有相同cookie的多个POST，GET请求？

Question

my question is, how can I call multiple requests via HttpWebRequest with same authenticate cookie in C#? I tried a lot of times but for now I dunno how to do it :/

My code is below:

        var postData = "method=loginFormAccount&args[0][email]=###&args[0][pass]=###&args[0][cache]=37317&args[]=1";
        var data = Encoding.ASCII.GetBytes(postData);

        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("###");
        request.CookieContainer = new CookieContainer();
        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.AllowAutoRedirect = true;            

        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        HttpWebResponse response = (HttpWebResponse)request.GetResponse();

        var cookies = new CookieContainer();
        cookies.Add(response.Cookies);

        System.IO.File.WriteAllText(@desktop + "\\post.html", new StreamReader(response.GetResponseStream()).ReadToEnd());

        // =================================== END LOGIN ==================================== \\

        System.IO.File.WriteAllText(@desktop + "\\cookie.html","");

        foreach (Cookie cook in response.Cookies)
        {
            using (System.IO.StreamWriter file = new System.IO.StreamWriter(@desktop + "\\cookie.html", true))
            {
                file.WriteLine(cook.ToString());
            }
            // Show the string representation of the cookie.                
        }

        HttpWebRequest requestNext = (HttpWebRequest)WebRequest.Create("####");
        requestNext.CookieContainer = cookies;
        requestNext.Method = "GET";

        HttpWebResponse responseNext = (HttpWebResponse)requestNext.GetResponse();

        //var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

        System.IO.File.WriteAllText(@desktop + "\\get.html", new StreamReader(responseNext.GetResponseStream()).ReadToEnd());

My main problem is that, cookie which I'm getting is the cookie BEFORE authenticate so I must to do something to get cookie AFTER authenticate.

Try this :

HttpWebRequest requestNext = (HttpWebRequest)WebRequest.Create("####");
requestNext.CookieContainer.Add(cookies);
