网上收集的WebBrowser的Cookie操作

1、WebBrowser设置Cookie
 1public partial class WebBrowserControl : Form
 2    {
 3        private String url;
 4
 5        [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
 6        public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData);
 7
 8        public WebBrowserControl(String path)
 9        {
10            this.url = path;
11            InitializeComponent();
12
13            // set cookie
14            InternetSetCookie(url, "JSESSIONID", Globals.ThisDocument.sessionID);
15
16            // navigate
17            webBrowser.Navigate(url);
18        }

19        
20}


 2、将WebBrowser的cookie信息传给HttpWebRequest.

先建一个"CookieContainer" 把WebBrowser中的Cookie保存在里面

//在WebBrowser中登录 cookie保存在 WebBrowser.Document.Cookie中     
 1          CookieContainer myCookieContainer = new CookieContainer();
 2
 3
 4            //String 的Cookie 要转成 Cookie型的 并放入CookieContainer中
 5            string cookieStr = webBrowser1.Document.Cookie;
 6            string[] cookstr = cookieStr.Split(';');
 7            foreach (string str in cookstr)
 8            {
 9                string[] cookieNameValue = str.Split('=');
10                Cookie ck = new Cookie(cookieNameValue[0].Trim().ToString(), cookieNameValue[1].Trim().ToString());
11                ck.Domain = "www.abc.com";//必须写对
12                myCookieContainer.Add(ck);
13            }

14
15            HttpWebRequest hreq = (HttpWebRequest)HttpWebRequest.Create("http://www.abc.com/search.asp");
16            hreq.Method = "POST";
17            hreq.ContentType = "application/x-www-form-urlencoded";
18         
19            //自己创建的CookieContainer
20            hreq.CookieContainer = myCookieContainer;
21         
22            string postdata = "id=2005&action=search&name=";
23            byte[] byte1 = Encoding.ASCII.GetBytes(postdata);
24            hreq.ContentLength = byte1.Length;
25          
26            Stream poststream = hreq.GetRequestStream();
27            poststream.Write(byte1, 0, byte1.Length);
28            poststream.Close();
29      
30            HttpWebResponse hres = (HttpWebResponse)hreq.GetResponse();
