C# 如何像java apache httpclient那样使用Asp.net 1.1 webrequest？

我是asp.net新手，我的服务器中有asp.net 1.1。

我想在后台-->登录到另一个站点并在其中导航为什么要使用12年前的框架版本？您正在寻找

CookieContainer

，而HtmlAgilityPack.CookieContainer在我的情况下不起作用。我做错了什么？将您的请求与来自Fiddler中真实浏览器的请求进行比较，看看有什么不同。现在我可以登录和导航了，在示例中，类似的登录是错误的。所缺少的是获得一个验证码给用户，用户将键入验证码，然后在后台执行该过程。可能吗？

 protected void Page_Load(object sender, EventArgs e)
{
  CookieContainer cookieJar = new CookieContainer();

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://www.4shared.com/web/login/validate");

  req.Method = "POST";
  req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
  req.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
  req.KeepAlive = true;
  req.Headers.Add("Keep-Alive: 300");
  req.AllowAutoRedirect = false;

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

  req.CookieContainer = cookieJar;

  String Username = "user%40email.com";
  String PassWord = "password";


  StreamWriter sw = new StreamWriter(req.GetRequestStream());
  sw.Write("login=" + Username + "&password=" + PassWord);
  sw.Close();

  HttpWebResponse response = (HttpWebResponse)req.GetResponse();

  StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(1255));
  string tmp = reader.ReadToEnd();






  HttpWebRequest req2 = (HttpWebRequest)HttpWebRequest.Create("http://www.4shared.com/account/home.jsp");
  req2.Method = "GET";
  req2.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
  req2.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
  req2.KeepAlive = true;
  req2.Headers.Add("Keep-Alive: 300");
  req2.CookieContainer = cookieJar;

  req2.ContentType = "text/html";

  HttpWebResponse response2 = (HttpWebResponse)req2.GetResponse();

  StreamReader reader2 = new StreamReader(response2.GetResponseStream(), Encoding.GetEncoding(1255));
  string tmp2 = reader2.ReadToEnd();

  response2.Close();
  Panel2.Text = tmp2;
