c# - How ways to return to "void" kind? -

i'm using on windows phone 8.1

try {     var url = "https://...../oauth/authorize?client_id=" + uri.escapedatastring("4a3e...") + "&response_type=code&redirect_uri=" + uri.escapedatastring("http://localhost:8888/callback") + "&show_dialog=true";     var starturi = new uri(url);     var enduri = new uri("http://localhost:8888/callback");      webauthenticationbroker.authenticateandcontinue(starturi, enduri,null, webauthenticationoptions.none); } catch (exception error) {     //     // bad parameter, ssl/tls errors , network unavailable errors handled here.     //     var dialog = new messagedialog(error.message);     await dialog.showasync(); } 

because webauthenticationbroker.authenticateandcontinue void kind cant put var t=webauthenticationbroker.authenticateandcontinue on

i want return below code

public async void continuewebauthentication(webauthenticationbrokercontinuationeventargs args) {     webauthenticationresult result = args.webauthenticationresult;      if (result.responsestatus == webauthenticationstatus.success)     {         //outputtoken(result.responsedata.tostring());         await getusernameasync(result.responsedata.tostring());     }     else if (result.responsestatus == webauthenticationstatus.errorhttp)     {         throw new exception("http error returned authenticateasync() : " + result.responseerrordetail.tostring());     }     else     {         throw new exception("error returned authenticateasync() : " + result.responseerrordetail.tostring());     } } 

void not "type" means method has no returned value. not need return statement.
