如何阅读网站 [英] how to read a website

问题描述

我想做一个非常简单的事情 - 点击一个网站并检索它的

给我（在C＃中）。我不得不承认我在MSDN

文档中丢失了一点。我能想到的最好的是我应该使用

HttpWebRequest.Create（URL）建立连接，但我不知道
知道从那里去哪里。是否有任何在线文档显示示例代码

来检索返回的html？或者，对于

的调用顺序是什么，最后得到页面的字符串表示？


提前感谢

解决方案

http://groups.google.com/groups?hl=e...phx.gbl& rnum = 5

或者只是搜索HttpWebRequest Stream


干杯，

Hi Axis，


这需要几步。以下代码是基本的方法，不使用任何标题


HttpWebRequest req =（HttpWebRequest）HttpWebRequest.Create（" http://www.google.com"） ;


HttpWebResponse resp =（HttpWebResponse）req.GetResponse（）;


StreamReader sr = new StreamReader（resp.GetResponseStream（））;


//获取文本（StreamReader默认使用UTF-8，但你可以更改它）

string html = sr.ReadToEnd（）; < br $>

//关闭溪流

sr.Close（）;

resp.Close（）;

I want to do a very simple thing -- hit a website and retrieve the html it
gives me (in C#). I have to admit I''m a little lost within the MSDN
documentation. The best I can figure is I should use
HttpWebRequest.Create(URL) to being setting up the connection, but I don''t
know where to go from there. Are there any online docs that show sample code
to retrieve the html that''s returned? Or, what''s the sequence of calls to
finally get a string representation of the page?

Thanks in advance

Hi,

Or just make a search for HttpWebRequest Stream

Cheers,

Hi Axis,

It requires a few steps. The following code is the basic way to do it, not using any headers

HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://www.google.com");

HttpWebResponse resp = (HttpWebResponse)req.GetResponse();

StreamReader sr = new StreamReader(resp.GetResponseStream());

// get the text (StreamReader uses UTF-8 by default, but you can change it)
string html = sr.ReadToEnd();

//close the streams
sr.Close();
resp.Close();
