How WP8.1 and UWP use the audio on the download page and save

WP8.1:

 Private   AsyncTask<storagefile>Getvoicedata () {HttpClient HttpClient=NewHttpClient (); varGetData =awaitHttpClient. Getstreamasync (NewUri ("Http://dx.sc.chinaz.com/Files/DownLoad/sound1/201207/1771.mp3")); varFile =awaitApplicationData.Current.LocalCacheFolder.CreateFileAsync ("1771.mp3", creationcollisionoption.replaceexisting); using(varstream =awaitfile. Openstreamforwriteasync ()) {awaitGetdata.copytoasync (stream);//The stream stream that will get the HttpClient stream copied to the fileawaitStream. Flushasync ();//Asynchronous Flush}returnThis_voice_files; }    }

UWP:

 Public AsyncTask<storagefile>Load () {Try    {        varHttpClient =NewHttpClient (); varBuffer =awaitHttpclient.getbufferasync (NewUri ("Http://dx.sc.chinaz.com/Files/DownLoad/sound1/201207/1771.mp3")); if(Buffer! =NULL&& buffer. Length >0u)        {            varFile =awaitApplicationData.Current.LocalCacheFolder.CreateFileAsync ("1771.mp3", creationcollisionoption.replaceexisting); using(varstream =awaitfile. OpenAsync (Fileaccessmode.readwrite)) {awaitStream.                WriteAsync (buffer); awaitStream.            Flushasync (); }            returnfile; }    }    Catch { }    return NULL;}

C#:

HttpClient client =NewHttpClient (); using(varMusicstream = client. Getstreamasync ("Http://dx.sc.chinaz.com/Files/DownLoad/sound1/201207/1771.mp3"). Result) {intCurrentpos =0; byte[] Tempbyte =New byte[4096]; MemoryStream Ms=NewMemoryStream (4096); //when you hit 0, you read it.                 Do{Currentpos= Musicstream.read (Tempbyte,0,4096); Ms. Write (Tempbyte,0, Currentpos); }  while(Currentpos! =0); File.writeallbytes ("C:\\test.mp3", Ms.                ToArray ()); System.Console.WriteLine ("OK"); }
