C#基于WebBrowser获取cookie的实现方法

private void BtnOpenUrl_Click(object sender, EventArgs e)
{
 if (txtUrl.Text != "")
 {
  MywebBrowser.Url = new Uri(txtUrl.Text);
 }
}
private void BtnGetCookie_Click(object sender, EventArgs e)
{
 CookieContainer myCookieContainer = new CookieContainer();
 if (MywebBrowser.Document.Cookie != null)
 {
  string cookieStr = MywebBrowser.Document.Cookie;
  string[] cookstr = cookieStr.Split(';');
  foreach (string str in cookstr)
  {
   string[] cookieNameValue = str.Split('=');
   Cookie ck = new Cookie(cookieNameValue[0].Trim().ToString(), cookieNameValue[1].Trim().ToString());
   ck.Domain = "www.google.com";
   myCookieContainer.Add(ck);
  }
 }
}
