如何HttpWebRequest模拟登陆，获取服务端返回Cookie以便登录请求后使用

public static string GetCookie(string requestUrlString, Encoding encoding, ref CookieContainer cookie)

{

//向服务端请求

HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(requestUrlString);

myRequest.ContentType = "application/x-www-form-urlencoded";

myRequest.CookieContainer = new CookieContainer();

//将请求的结果发送给客户端(界面、应用)

HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();

cookie.Add(myResponse.Cookies);

StreamReader reader = new StreamReader(myResponse.GetResponseStream(), encoding);

return reader.ReadToEnd();

}

public static string GetHtml(string requestUrlString, Encoding encoding, CookieContainer cookie)

string ua = "Mozilla/5.0 (Linux; U; Android 2.2; en-us; Nexus One Build/FRF91) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1";

myRequest.UserAgent = ua;

myRequest.CookieContainer = cookie;

public static string PostLogin(string postData, string requestUrlString, ref CookieContainer cookie)

ASCIIEncoding encoding = new ASCIIEncoding();

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

myRequest.Method = "POST";

myRequest.ContentLength = data.Length;

Stream newStream = myRequest.GetRequestStream();

newStream.Write(data, 0, data.Length);

newStream.Close();

StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);

public static string PostRequest(string postData, string requestUrlString, CookieContainer cookie)
