my webBrowser is in public , is there any way to useing webbrowser cookie in webrequest ?

Answer 1

You can use a CookieContainer for a Webrequest.

 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.

Ok, you want to do a log in. Thats is different story. You can use NetworkCredential for that.

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.

Answer 3

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)

see http://msdn.microsoft.com/en-us/library/dd920295(VS.95).aspx about the network stacks in silverlight since version 3
