我要评论复制代码 代码如下:
private void button2_click(object sender, eventargs e)
{
// create a request for the url.
webrequest request = webrequest.create("http://www.baidu.com/");
// if required by the server, set the credentials.
request.credentials = credentialcache.defaultcredentials;
// get the response.
httpwebresponse response = (httpwebresponse)request.getresponse();
// display the status.
messagebox.show(response.statusdescription);
console.writeline(response.statusdescription);
// get the stream containing content returned by the server.
stream datastream = response.getresponsestream();
// open the stream using a streamreader for easy access.
streamreader reader = new streamreader(datastream, encoding.default);
// read the content.
string responsefromserver = reader.readtoend();
//截取数据
int i = responsefromserver.indexof("京");
string databid = responsefromserver.substring(i, 12);
// display the content.
messagebox.show(databid);
console.writeline(responsefromserver);
// cleanup the streams and the response.
reader.close();
datastream.close();
response.close();
}
