c# - Get specific data from a webpage -

i have page, , page need value other different page.

i want retrieve 6 numbers "números sorteados" box.

so far succeeded in whole web page this:

webrequest request = webrequest.create("http://www1.caixa.gov.br/loterias/loterias/ultimos_resultados.asp"); webresponse response = request.getresponse(); stream data = response.getresponsestream(); string html = string.empty; using (streamreader sr = new streamreader(data)) {     html = sr.readtoend(); } 

after that, can't select these number html.

here's quick way numbers using htmlagilitypack:

public async task<list<string>> getnumbers() {     // getting number of microseconds since jan 1st, 1970     var microseconds = (long)(datetime.utcnow - (new datetime(1970, 1, 1, 0, 0, 0))).totalmilliseconds;     // creating webrequest , passing parameter     var request =         webrequest.createhttp(             string.format(                 "http://www1.caixa.gov.br/loterias/loterias/megasena/megasena_pesquisa_new.asp?app={0}",                 microseconds));     // adding cookie container otherwise stuck in redirect loop     var jar = new cookiecontainer();     request.cookiecontainer = jar;      try     {         var response = await request.getresponseasync();         using (var sr = new streamreader(response.getresponsestream()))         {             var html = await sr.readtoendasync();             var document = new htmlagilitypack.htmldocument();             document.loadhtml(html);             var nodes = document.documentnode.selectnodes("//span [@class=\"num_sorteio\"]");             var numbersnodes = nodes.last().selectnodes("//li");              // selecting last 6 nodes represent "números sorteados" numbers             return numbersnodes.select(node => node.innertext).skip(6).tolist();         }     }     catch (exception e)     {         // basic exception handling.         console.writeline(e);     }     return null; }  

and call function it's easy as:

list<string> numbers = await getnumbers();
