        {

            InitializeComponent();

        }



         public CookieContainer cook = new CookieContainer();



        private void button1_Click(object sender, EventArgs e)

        {

            string url = "http://localhost/admin/login.php";

            byte[] data = Encoding.UTF8.GetBytes("gotopage=%2Fjianongadmin%2F&dopost=login&adminstyle=newdedecms&userid=admin&pwd=admin&sm1=");

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(new Uri(url));

            

            //定义表头信息

            request.CookieContainer = cook;//cookie容器



            request.Method = "POST";

            textBox1.Text = read.ReadToEnd();

            UpdateCookie(ref cook, resphone.Cookies);  //写入cookie



             



        }
