c# - How to get the values from Html.ListBox in asp.net MVC -

-

i had before

<div class="form-group">     @html.label("empresa", new { @class = "control-label col-md-2" })     <div class="col-md-10">        @html.dropdownlist("empresa",           new selectlist(empresas, "id", "nombre"),           new { @class = "form-control" })      </div> </div>

and on controller values: (check request.form line)

      public async task<actionresult> create(         [bind(             include =                 "userprincipalname,accountenabled,passwordprofile,mailnickname,displayname,givenname,surname,jobtitle,department"             )] microsoft.azure.activedirectory.graphclient.user user)     {         activedirectoryclient client = null;         try         {             client = authenticationhelper.getactivedirectoryclient();         }         catch (exception e)         {             if (request.querystring["reauth"] == "true")             {                 //                 // send openid connect sign-in request new set of tokens.                 // if user still has valid session azure ad, not prompted credentials.                 // openid connect middleware return controller after sign-in response has been handled.                 //                 httpcontext.getowincontext()                     .authentication.challenge(openidconnectauthenticationdefaults.authenticationtype);             }              //             // user needs re-authorize.  show them message effect.             //             viewbag.errormessage = "authorizationrequired";             return view();         }          try         {             var usuario = user.userprincipalname;             user.userprincipalname = usuario+settingshelper.domain;             user.mailnickname = usuario;             user.accountenabled = true;             await client.users.adduserasync(user);              string extproplookupname = string.format("extension_{0}_{1}", settingshelper.clientid.replace("-", ""), "compania");              //to finished             user.setextendedproperty(extproplookupname, request.form["empresa"].tostring());             await user.updateasync();             //task.waitall();              // save extended property value azure ad.             user.getcontext().savechanges();             return redirecttoaction("index");         }         catch (exception exception)         {             modelstate.addmodelerror("", exception.message);             return view();         }     }

however changed dropdownlist listbox because need multipleselect, , dont see in request.form collection

how can values selected?

use formcollection have here.

like so:

public actionresult myaction(formcollection formcollection) {     var addeditems = formcollection["empresa"].split(',');      //....more code stuff items }
