WebClient usage for Windows Phone development

Note:
For personal use, WebClient usage has many similarities with WebService access. The difference is that WebService requires a local web reference, but WebClient does not. In addition, WebClient is easier to change the accessed URL.
For example, access is as follows:

String url = "http://www.youdao.com/smartresult-xml/search.s? Jsflag = true & type = Mobile & Q = "+ phone. text. trim (). tostring (); WebClient client = new WebClient (); client. downloadstringcompleted + = new downloadstringcompletedeventhandler (client_downloadstringcompleted); client. downloadstringasync (New uri (URL, urikind. absolute); void client_downloadstringcompleted (Object sender, downloadstringcompletedeventargs e ){}

CodeNote:
The URL is a Web interface used to query the home location by phone number.
Because the phone number is dynamically changing, it is more convenient to use WebClient.

Here, I found some interfaces for phone number attribution query, but they are all in GBK encoding format. WP cannot identify GBK encoding, so Chinese characters may be garbled.
