使用HttpWebRequest访问多个页面实现用同一Session

代码是很久很久以前写的了....现在把它放出来..

string url = "http://localhost:2677/WebSite3/Default2.aspx";
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.CookieContainer = new CookieContainer();

        string s = "loginuser=1&password=1&logintype=%C1%AC%CF%DF%B9%FA%BC%CA&domainid=1&&refer=http%3A%2F%2F210.34.241.100%2Fphp%2Fonlinestatus.php%3Flogout_offnet%3D1&x=32&y=12";

        byte[] requestBytes = System.Text.Encoding.ASCII.GetBytes(s);
        req.Method = "POST";
        req.ContentType = "application/x-www-form-urlencoded";
        req.ContentLength = requestBytes.Length;
        Stream requestStream = req.GetRequestStream();
        requestStream.Write(requestBytes, 0, requestBytes.Length);
        requestStream.Close();
        HttpWebResponse res = (HttpWebResponse)req.GetResponse();

        res.Cookies = req.CookieContainer.GetCookies(req.RequestUri);

        CookieCollection cook;
        cook = res.Cookies;

        string url1 = "http://localhost:2677/WebSite3/Default3.aspx";
        HttpWebRequest req1 = (HttpWebRequest)WebRequest.Create(url1);
        req1.CookieContainer = new CookieContainer();
        req1.CookieContainer.Add(res.Cookies);
        req1.Method = "GET";
        HttpWebResponse res1 = (HttpWebResponse)req1.GetResponse();
        StreamReader sr1 = new StreamReader(res1.GetResponseStream(), System.Text.Encoding.Default);
        string backstr1 = sr1.ReadToEnd();
        sr1.Close();
        res1.Close();
        res.Close();
        if (backstr1.IndexOf("连线成功") != -1)
        {
           
        }

代码比较乱.- -是很乱..但都是简单的语句还是很好理解的...
