我正在嘗試使用htmlagility pack來獲得結果的鏈接和結果

我有這個代碼

using HtmlAgilityPack;

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.IO;

using System.Linq;

using System.Net;

using System.ServiceModel.Syndication;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

using System.Xml;

namespace Search

{

public partial class Form1 : Form

{

// load snippet

HtmlAgilityPack.HtmlDocument htmlSnippet = new HtmlAgilityPack.HtmlDocument();

public Form1()

{

InitializeComponent();

}

private void btn1_Click(object sender, EventArgs e)

{

listBox1.Items.Clear();

StringBuilder sb = new StringBuilder();

byte[] ResultsBuffer = new byte[8192];

string SearchResults = "http://google.com/search?q=" + txtKeyWords.Text.Trim();

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(SearchResults);

HttpWebResponse response = (HttpWebResponse)request.GetResponse();

Stream resStream = response.GetResponseStream();

string tempString = null;

int count = 0;

do

{

count = resStream.Read(ResultsBuffer, 0, ResultsBuffer.Length);

if (count != 0)

{

tempString = Encoding.ASCII.GetString(ResultsBuffer, 0, count);

sb.Append(tempString);

}

}

while (count > 0);

string sbb = sb.ToString();

HtmlAgilityPack.HtmlDocument html = new HtmlAgilityPack.HtmlDocument();

html.OptionOutputAsXml = true;

html.LoadHtml(sbb);

HtmlNode doc = html.DocumentNode;

foreach (HtmlNode link in doc.SelectNodes("//a[@href]"))

{

//HtmlAttribute att = link.Attributes["href"];

string hrefValue = link.GetAttributeValue("href", string.Empty);

if (!hrefValue.ToString().ToUpper().Contains("GOOGLE") && hrefValue.ToString().Contains("/url?q=") && hrefValue.ToString().ToUpper().Contains("HTTP://"))

{

int index = hrefValue.IndexOf("&");

if (index > 0)

{

hrefValue = hrefValue.Substring(0, index);

listBox1.Items.Add(hrefValue.Replace("/url?q=", ""));

}

}

}

}

}

}

此代碼返回查詢的結果鏈接我想獲得每個鏈接的標題標簽我如何獲得每個鏈接的標題？

任何人都可以幫忙嗎？
