void Page_Load (Object sender, EventArgs e)
{
String strurl= "Http://blog.hnce.net"; The address of the Web page you want to get
WebClient mywebclient=new WebClient (); Create WebClient instance Mywebclient
Gets or sets the network credentials used to authenticate requests to Internet resources.
Mywebclient.credentials=credentialcache.defaultcredentials;
Downloads data from a resource and returns a byte array. (add @ Because there is a "/" symbol in the middle of the URL)
Byte[] Pagedata=mywebclient.downloaddata (strURL);
The following two sentences can be used one at a time, the function is the same is used to convert character set, according to get the Site page character encoding selection
String result=encoding.default.getstring (Pagedata);
If you get the site page using GB2312, use this sentence
String result=encoding.utf8.getstring (Pagedata);
If you get the site page using UTF-8, use this sentence
Because my blog uses the UTF-8 code, so here I use this sentence
Response.Write (Result); Show what gets in a Web page
}
