1.先取得網頁的原代碼
?Uri?url=new?Uri("http://www.aygfsteel.com/wujun");
????????????HttpWebRequest?request=(HttpWebRequest)?WebRequest.Create(url);
????????????HttpWebResponse?response?=?(HttpWebResponse)request.GetResponse();
????????????Stream?stream?=?response.GetResponseStream();
????????????StreamReader?sr?=?new?StreamReader(stream);
????????????string?str=sr.ReadToEnd();
????????????sr.Close();
????????????stream.Close();
????????????response.Close();
得到網頁的html源代碼以后。再根據源代碼分析 所有 <a href ="url">?? 最后得到 href后面? url的鏈接地址
正則表達式
????Regex?RegExFindHref?=?new?Regex(@"<a\s+([^>]*\s*)?href\s*=\s*(?:""(?<1>[/\a-z0-9_][^""]*)""|'(?<1>[/\a-z0-9_][^']*)'
|(?<1>[/\a-z0-9_]\S*))(\s[^>]*)?>(?<2>.*?)</a>",?RegexOptions.Singleline?|?RegexOptions.IgnoreCase?|?RegexOptions.Compiled);
循環讀出 連接地址
?????for?(Match?m?=?RegExFindHref.Match(str);?m.Success;?m?=?m.NextMatch())
????????????{
???????????????TextBox1.Text+=?m.Groups[1].ToString()+"\n";
????????????
????????????}
運行后
TextBox1 將顯示分析后的所有網頁的連接 :
