用C#做一个模拟登陆页面，不能返会响应后的页面

C# code


 String loginUrl = "http://localhost/yh/admin/login.asp";
 CookieContainer session = new CookieContainer();
 
 public void getLoginPage()
        {
            string strUsername = tb_username.Text.Trim();
            string strPassword = tb_password.Text.Trim();

            ASCIIEncoding encoding = new ASCIIEncoding();
            string postData = "username=" + strUsername;
            postData += ("&password=" + strPassword);

            //postData = "username=steve&password=123456a%mofei=7049&submit=%C8%B7+%B6%A8";

            byte[] data = encoding.GetBytes(postData);

            // Prepare web request...   
            HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(loginUrl);                 

            myRequest.CookieContainer = session;

            myRequest.Method = "POST";
            myRequest.ContentType = "application/x-www-form-urlencoded";
            myRequest.ContentLength = data.Length;
            Stream newStream = myRequest.GetRequestStream();            
            // Send the data.   
            newStream.Write(data, 0, data.Length);       
            newStream.Close();

            // Get response   
            HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
            StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.Default);
            string content = reader.ReadToEnd();

            richTextBox1.Text = richTextBox1.Text + content;


        }
