我想模拟163用户登录，通过了抓包分析得到路径（我不能确保我的分析是否正确）希望有人能帮忙分析一下，新手上路。。。我的主要代码如下：

private void GetCookies()
{
string username = "lstcJaney@163.com";
string password = "08339314lry";
string url2 = "http://email.163.com/errorpage/err_163.htm";
CookieContainer myCookieContainer = new CookieContainer();
string indata = string.Empty;
string url = "https://ssl.mail.163.com/entry/coremail/fcg/ntesdoor2?funcid=loginone&language=-1&passtype=1&iframe=1&product=mail163&from=web&df=email163&module=&uid=lstcJaney@163.com&style=-1";
indata = "username=" + username + "&url2=" + url2 + "&savelogin=0&password=" + password;
PostData(url, indata, myCookieContainer);
url = "http://uinfo.mail.163.com/contactproxy/getbdayinfo.do?uid=lstcjaney@163.com&view=bdayinfo_client";
string backurl = "http://webmail.mail.163.com/app/api/service_backurl.jsp?sid=rBWPCXagzGnwJNrZhqggNMrsNUgAxNEN&callback=parent.$I('product.Gift').load";
indata = "fids=" + username.ToLower() + "&backurl=" + backurl;
PostData(url, indata, myCookieContainer);
//url = "http://webmail.mail.163.com/app/api/service_backurl.jsp?sid=rBWPCXagzGnwJNrZhqggNMrsNUgAxNEN&callback=parent.$I('product.Gift').load";
//indata = "contact={\"code\":\"201\",\"pcode\":\"201\"}";
//PostData(url, indata, myCookieContainer);
this.webBrowser1.Navigate("http://webmail.mail.163.com/js4/main.jsp?sid=vAtsbBlJTLQGVIsrTjJJyajpYIEXuJOr#module=welcome.WelcomeModule");

}

public static string PostData(string url, string indata, CookieContainer myCookieContainer)
{
string outdata = "";

myHttpWebRequest.CookieContainer = myCookieContainer;
try
{
Stream myRequestStream = myHttpWebRequest.GetRequestStream();
StreamWriter myStreamWriter = new StreamWriter(myRequestStream, Encoding.GetEncoding("gb2312"));
myStreamWriter.Write(indata);
myStreamWriter.Close();
myRequestStream.Close();
