You can use a CookieContainer for a Webrequest.
您可以将 CookieContainer 用于 Web 请求。
web_cookies = new CookieContainer();
// Create a 'WebRequest' object with the specified url.
HttpWebRequest myWebRequest = (HttpWebRequest)WebRequest.Create(url);
myWebRequest.CookieContainer = web_cookies;
Hope this helps.
希望这可以帮助。
Ok, you want to do a log in. Thats is different story. You can use NetworkCredential for that.
好的，你想登录。那是另一回事。您可以为此使用 NetworkCredential。
public string get_secure_webpage(string url, string username, string password)
{
WebRequest myWebRequest = WebRequest.Create(url);
NetworkCredential networkCredential = new NetworkCredential(username, password);
myWebRequest.Credentials = networkCredential;
...

public CookieContainer GetCookieContainer()
{
CookieContainer container = new CookieContainer();
foreach (string cookie in webBrowser1.Document.Cookie.Split(';'))
{
string name = cookie.Split('=')[0];
string value = cookie.Substring(name.Length + 1);
string path = "/";
string domain = ".google.com"; //change to your domain name
container.Add(new Cookie(name.Trim(), value.Trim(), path, domain));
}
return container;
}
This will work on most sites, however sites that use subdomains might be a problem.
这适用于大多数站点，但是使用子域的站点可能会出现问题。

is this silverlight? if so, since silverlight 3 if you use the browser network stack than you should get cookies for free. By default you get the browser stack when you create n HttpWebrequest using the WebRequest.Create() method. note if you use CreateHTTP method, you get a client stack, which does not include browser cookies by default (you have to do trickery to get them, as described previously)
这是银光吗？如果是这样，从 Silverlight 3 开始，如果您使用浏览器网络堆栈，那么您应该免费获得 cookie。默认情况下，当您使用 WebRequest.Create() 方法创建 n HttpWebrequest 时，您将获得浏览器堆栈。请注意，如果您使用 CreateHTTP 方法，您将获得一个客户端堆栈，默认情况下该堆栈不包含浏览器 cookie（您必须使用技巧才能获取它们，如前所述）
