嗨我使用此代碼從ebay獲取一些數據。C#HAP「System.Net.WebException:遠程名稱無法解析」異常
string url = textBox1.Text;
get_all_link(url);
private void get_all_link(string url)
{
var webGet = new HtmlWeb();
try
{
var document = webGet.Load(url);
MessageBox.Show(url);
var metaTags = document.DocumentNode.SelectNodes("//div[@class='ttl']/a");
if (metaTags != null)
{
foreach (var tag in metaTags)
{
string link = tag.Attributes["href"].Value;
links.Add(link);
}
}
var next = document.DocumentNode.SelectNodes("//td[@class='botpg-next']/a");
if (next != null)
{
string link = "http://www.ebay.com" + next;
get_all_link(link);
}
else return;
}
catch (Exception f)
{
MessageBox.Show(f.ToString());
TextWriter tw = new StreamWriter("data.txt");
tw.WriteLine(f.ToString());
tw.Close();
}
}
System.Net.WebException: The remote name could not be resolved: 'www.ebay.comhtmlagilitypack.htmlnodecollection' at System.Net.HttpWebRequest.GetResponse() at HtmlAgilityPack.HtmlWeb.Get(Uri uri, String method, String path, HtmlDocument doc, IWebProxy proxy, ICredentials creds) in C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlWeb.cs:line 1446 at HtmlAgilityPack.HtmlWeb.LoadUrl(Uri uri, String method, WebProxy proxy, NetworkCredential creds) in C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlWeb.cs:line 1563 at HtmlAgilityPack.HtmlWeb.Load(String url, String method) in C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlWeb.cs:line 1152 at HtmlAgilityPack.HtmlWeb.Load(String url) in C:\Source\htmlagilitypack\Trunk\HtmlAgilityPack\HtmlWeb.cs:line 1107 at BackgroundWorker.Form1.get_all_link(String url) in C:\Documents and Settings\maruf\My Documents\Visual Studio 2008\Projects\BackgroundWorker\BackgroundWorker\Form1.cs:line 86
我在這裏查了一些帖子。但無法解決這個問題。我該如何解決這個問題?任何建議?在此先感謝:)
謝謝。現在工作正常:) – qmaruf 2011-12-22 10:02:39
