For Windows Phone 7 and sliverlight, download the webpage for parsing, about WP7 gb2312 encoding)

Silverlight and WP7 (Windows Phone 7) do not support gb2312 decoding by default,

Therefore, most of the HTML downloaded from the internet is garbled.

Example: http://news.sina.com.cn/s/2011-11-25/120923524756.shtml

The following shows a WP7Program

 1 WebClient webclenet = New WebClient ();
 2 Webclenet. downloadstringasync ( New Uri ( "  Http://news.sina.com.cn/s/2011-11-25/120923524756.shtml  " , Urikind. relativeorabsolute ));
 3 Webclenet. downloadstringcompleted + = New Downloadstringcompletedeventhandler (webclenet_downloadstringcompleted );

 10 Callback event:
 11   Void Webclenet_downloadstringcompleted ( Object Sender, downloadstringcompletedeventargs E)
 12 {
 13               String S = E. result;
 14 }

Debugging found

 

Almost all are garbled issues.

Setting the encoding to UTF-8 is also garbled.

Therefore, an open-source library htmlagilitypack (including encoding and processing of HTML nodes) is referenced)

For: http://www.codeplex.com/htmlagilitypack

Reference htmlagilitypack. DLL to the project. A prompt will pop up, probably because this is not a Windows Phone class library. Ignore it and confirm it directly.

Then modify ourCode

WebClient webclenet =New WebClient ();

Webclenet. Encoding =New Htmlagilitypack. gb2312encoding ();// Add this encoding statement

Webclenet. downloadstringasync (New Uri (Http://news.sina.com.cn/s/2011-11-25/120923524756.shtml", Urikind. relativeorabsolute ));

Webclenet. downloadstringcompleted + =New Downloadstringcompletedeventhandler (webclenet_downloadstringcompleted );

 

Debug the result

 

Finally we can see our Chinese.

At the same time, htmlagilitypack not only helps us solve the gb2312 encoding problem, it is also a powerful tool for us to parse HTML ~!
