1.先取得網(wǎng)頁(yè)的原代碼
?Uri?url=new?Uri("http://m.tkk7.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(wǎng)頁(yè)的html源代碼以后。再根據(jù)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(dá)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(huán)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(yùn)行后
TextBox1 將顯示分析后的所有網(wǎng)頁(yè)的連接 :
