System.out.println("\n######" + readlength + "######");
} catch (MalformedURLException ex) {

}
}
类似代码

Answer 3

上面那段已经解决了,能不能再问一下
            WebBrowser webb = new WebBrowser();
            webb.Navigate("about:blank");
            HtmlDocument htmldoc = webb.Document.OpenNew(true);
            htmldoc.Write(strDetail);
            HtmlElementCollection htmlTR = htmldoc.GetElementsByTagName("TR");
            foreach (HtmlElement tr in htmlTR)
            {
               .....
            }
