winform 和 cookies

Question

有网站 www.abc.com
现已获得他的cookies的字符串 sCookie
string sCookie = "xxxxxxxx";用webBrowser控件的Navigate方法可以访问www.abc.com，但不是登录状态
请教如何让webBrowser用这个sCookie让他自动登录

Answer 1

[DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
  public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData);
  
 InternetSetCookie(url, "", Globals.ThisDocument.sessionID);

Answer 2

谢谢wuyq11, 不过好像不行呀，代码都通过了，但是没有登录成功。可以确认这个cookie是有效的，请帮忙看下下面代码有什么问题        [DllImport("wininet.dll", CharSet = CharSet.Auto, SetLastError = true)]
        public static extern bool InternetSetCookie(string lpszUrlName, string lbszCookieName, string lpszCookieData);
          private void toolStripTextBox1_KeyDown(object sender, KeyEventArgs e)
        {
            string sCookie = "xxxxx";
            if (e.KeyCode == Keys.Enter)
            {                string url = toolStripTextBox1.Text;                SetCookie(url, "", sCookie);
                Navigate(url);
            }
        }        public static void SetCookie(string siteUrl, string cookieName, string cookieData)
        {
            if (!InternetSetCookie(siteUrl, cookieName, cookieData))
            {
                throw new Exception("Exception setting cookie: Win32 Error code=" + Marshal.GetLastWin32Error());
            }
        }        // Navigates to the given URL if it is valid.
        private void Navigate(String address)
        {
            if (String.IsNullOrEmpty(address)) return;
            if (address.Equals("about:blank")) return;
            if (!address.StartsWith("http://") &&
                !address.StartsWith("https://"))
            {
                address = "http://" + address;
            }
            try
            {
                webBrowser1.Navigate(new Uri(address));
            }
            catch (System.UriFormatException)
            {
                return;
            }
        }

Answer 3

加入下面代码后解决问题
                foreach (string c in sCookie.ToString().Split(';'))
                {
                    string[] item = c.Split('=');
                    string name = item[0];
                    string value = item[1];
                    InternetSetCookie(url, name, value);
                }
