如何使用c#从网络博客中阅读博客文章? [英] How to read blog post from a web blog using c# ?

问题描述

你好

我的基于C#的网站包含两个文本框.txtURL和txtRead以及一个按钮btnRead.

我希望我放置一个网络博客的帖子链接....例如，对于博客http://www.withpc.in/，现在对博客http://www.withpc.in/2011/08 /top-social-media-website-beyond.html

我想要的是，如果我将链接添加到txtURL并单击btnRead，则该帖子进入文本框txtRead(仅是帖子文本)

这就像去一个网站并在那里阅读帖子.我想使用C#进入我的文本框中的同一篇文章，以便我可以使用文本框在页面上阅读它.


我也尝试了这段代码，但它提供了页面的html编码，我想要的是帖子内容.

Hello

My website based on C# contains two text boxes.. txtURL and txtRead and a button btnRead.

I want that if i put a web blog''s post link.... i.e. for the blog http://www.withpc.in/ and now for the post http://www.withpc.in/2011/08/top-social-media-website-beyond.html

I want that if i add the link to the txtURL and Click on btnRead then the Post comes to textbox txtRead (only the post text )

It is like going to a website and reading a post there. The same post i want to get on my text box using C# so that i can read it on my page using textbox.


Also i tried this code but it gives the html coding of the page and i want is the post content.

using System; 
using System.IO; 
using System.Net; 
using System.Text; 


    public static void GetFile 
            ( 
            string strURL, 
            string strFilePath 
            ) 
        { 

            WebRequest myWebRequest = WebRequest.Create(strURL);  

            WebResponse myWebResponse = myWebRequest.GetResponse();  

            Stream ReceiveStream = myWebResponse.GetResponseStream(); 
                
            Encoding encode = System.Text.Encoding.GetEncoding("utf-8"); 

            StreamReader readStream = new StreamReader( ReceiveStream, encode ); 

            string strResponse=readStream.ReadToEnd(); 
                 
            StreamWriter oSw=new StreamWriter(strFilePath); 
     
            oSw.WriteLine(strResponse); 

            oSw.Close(); 

            readStream.Close(); 
         
            myWebResponse.Close(); 

        } 

因此，请向我建议阅读博客内容的方法.

谢谢

So please suggest me the methods to read the blog content.

Thanks

推荐答案

最后尝试一下.

Try this at the end.

Dim wb As New WebBrowser
Dim doc As HtmlDocument
wb.Document.Write(IO.File.ReadAllText(strFilePath))
'You can get result by
'wb.Document.GetElementById("main-wrapper").InnerText

这将使您获得所有评论的帖子. main-wrapper是保存这些内容的div.另一种方法是解析文件中的HTML内容.

This will get you the post with all comments. main-wrapper is the div which holds these content. The other way is to parse the HTML content in the file.
