【CSharp】获取网页信息

作者: / 发布于2013/7/19/ 892

想获取网页的某个信息，比如：博客园的文章标题。现在只能获取到整个页面的信息，具体怎么获取标题的信息和更详细的信息，请高手指教。很想学习抓取网页信息知识，请高手们指教，我的代码是放在按钮的click下面的。


	// Create a request for the URL.
	 WebRequest request = WebRequest.Create("http://www.cnblogs.com/");
	 // If required by the server, set the credentials.
	 request.Credentials = CredentialCache.DefaultCredentials;
	 // Get the response.
	 HttpWebResponse response = (HttpWebResponse)request.GetResponse();
	 // Display the status.
	 Response.Write(response.StatusDescription);
	 // Get the stream containing content returned by the server.
	 Stream dataStream = response.GetResponseStream();
	 // Open the stream using a StreamReader for easy access.
	 StreamReader reader = new StreamReader(dataStream, Encoding.UTF8);
	 // Read the content.
	 string responseFromServer = reader.ReadToEnd();
	 // Display the content.
	 Response.Write(responseFromServer);
	 // Cleanup the streams and the response.
	 reader.Close();
	 dataStream.Close();
	 response.Close();
