C# 模拟登录后，怎样打开登录后的网页页面？

[Nikomememe]

如题，C#模拟登录网页（具体是博客），登录成功后（代码实现，自己已经把登录的代码写出来了），怎样打开登录后的页面？需要调用哪个函数（本人新手），csdn的热心朋友，帮帮忙！谢谢!有代码就贴一下吧！

记录下Cookei打开别的页面的时候把你登录后的Cookie发送过去。

两钻大哥，好激动啊！我的代码如下：
public class HttpHelper
{
public static CookieContainer Cookies = new CookieContainer();
public static string GetHttpResponse(string url, string postdata)
{
try
{
HttpWebRequest MyRequest = (HttpWebRequest)WebRequest.Create(url);
MyRequest.Method = "POST";
MyRequest.ContentLength = postdata.Length;
MyRequest.CookieContainer = Cookies;
MyRequest.KeepAlive = true;
MyRequest.AllowAutoRedirect = true;
MyRequest.ContentType = "application/x-www-form-urlencoded";
MyRequest.UserAgent = " Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1";
MyRequest.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";

if (postdata != null)
{
ASCIIEncoding MyEncoding = new ASCIIEncoding();
byte[] MyByte = MyEncoding.GetBytes(postdata);
Stream MyStream = MyRequest.GetRequestStream();
MyStream.Write(MyByte, 0, postdata.Length);
MyStream.Close();
}

string getContent = null;
Encoding myEncoding = Encoding.GetEncoding("UTF-8");
HttpWebResponse MyResponse = (HttpWebResponse)MyRequest.GetResponse();
if (MyResponse.StatusCode == HttpStatusCode.OK)
{

/*获取响应页面cookie*/
// MyResponse.Cookies = MyRequest.CookieContainer.GetCookies(MyRequest.RequestUri);

//CookieCollection cook = MyResponse.Cookies;
//string strCook = MyRequest.CookieContainer.GetCookieHeader(MyRequest.RequestUri);




//MessageBox.Show("adfdfasdf");
Stream MyNewStream = MyResponse.GetResponseStream();
StreamReader MyStreamReader = new StreamReader(MyNewStream, myEncoding);
getContent = MyStreamReader.ReadToEnd();
MyStreamReader.Close();
}
MyResponse.Close();
return getContent;
}
catch (Exception)
{
return string.Empty;
}
}
请问：登录后的cookie是保存在public static CookieContainer Cookies = new CookieContainer();中的Cookie中吗？这个Cookie是不是就是你说的做为访问登录页面需要的cookie呢？真的很希望得到你的帮助和回答，有范例代码就贴一贴吧！呵呵，再次感谢你！我是新手，上面的代码也不是很理解，这知道大概个原理和过程！
