该法典:

        string url = urlTextBox.Text;
        string sourceCode = Extractor.getSourceCode(url);

        HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
        doc.LoadHtml(sourceCode);
        List<string> links = new List<string>();

        if (links != null)
        {
            foreach (HtmlAgilityPack.HtmlNode nd in doc.DocumentNode.SelectNodes("//a[@href]"))
            {
                links.Add(nd.Attributes["href"].Value);
            }
        }
        else
        {
            MessageBox.Show("No Links Found");
        }

        if (links != null)
        {
            foreach (string str in links)
            {
                richTextBox9.Text += str + "
";
            }
        }
        else
        {
            MessageBox.Show("No Link Values Found");
        }

我如何能够这样做?

为什么不只取代:

links.Add(nd.Attributes["href"].Value);

为此:

if (nd.Attributes["href"].Value.Contains("docid="))
    links.Add(nd.Attributes["href"].Value);
