c# - How to bind a dictionary value to a column in asp.net mvc -

i using active directory authentication library list of users in active directory. view bound user class in library.

@using microsoft.azure.activedirectory.graphclient @model ienumerable<user>   @{     viewbag.title = "index";     layout = "~/areas/globaladmin/views/shared/_layoutglobaladmin.cshtml"; } <h2>usuarios</h2>  <div class="wrapper wrapper-content animated fadeinright">     <div class="row">         <div class="col-lg-12">             <div class="ibox float-e-margins">                 <div class="ibox-title">                     <h5>lista de usuarios</h5>                     <div class="ibox-tools">                         @html.actionlink("create new", "create", null, new { @class = "btn btn-primary btn-xs" })                     </div>                 </div>                 <div class="ibox-content">                      <table id="directoryobjects" class="table table-bordered table-striped">                         <tr>                             <th>                                 userprincipalname                             </th>                             <th>                                 displayname                             </th>                             <th>                                 jobtitle                             </th>                             <th>                                 objectid                             </th>                             <th />                         </tr>                         @foreach (var item in model)     {         var user = item user;                         <tr>                             <td>                                 @html.displayfor(modelitem => user.userprincipalname)                             </td>                             <td>                                 @html.displayfor(modelitem => user.displayname)                             </td>                             <td>                                 @html.displayfor(modelitem => user.jobtitle)                             </td>                             <td>                                 @html.displayfor(modelitem => user.objectid)                             </td>                             <td>                                 @html.actionlink("edit", "edit", new { objectid = item.objectid }) <br />                                 @html.actionlink("details", "details", new { objectid = item.objectid }) <br />                                 @html.actionlink("delete", "delete", new { objectid = item.objectid })  <br />                                 @html.actionlink("groupmembership", "getgroups", new { objectid = item.objectid }) <br />                                 @html.actionlink("directreports", "getdirectreports", new { objectid = item.objectid }) <br />                             </td>                         </tr>     }                     </table>                  </div>             </div>         </div>     </div> </div> 

however in active directory can create custom properties, properties called schema extensions: fyi http://justazure.com/azure-active-directory-part-6-schema-extensions/

in list of users users have custom properties others dont.

in view want create column show value of custom property if exists.

i know how value server side, dont know how bind on html

this index action in users controller

 public async task<actionresult> index()     {         var userlist = new list<microsoft.azure.activedirectory.graphclient.user>();         try         {             activedirectoryclient client = authenticationhelper.getactivedirectoryclient();             ipagedcollection<iuser> pagedcollection = await client.users.executeasync();             if (pagedcollection != null)             {                                 {                     list<iuser> userslist = pagedcollection.currentpage.tolist();                     foreach (iuser user in userslist)                     {                         var usuarioad = (microsoft.azure.activedirectory.graphclient.user)user;                         var extendedproperties = usuarioad.getextendedproperties();                          foreach (var property in extendedproperties)                         {                             if (property.key.contains("compania"))                             {                                 string value = property.value.tostring();                             }                         }                          userlist.add((microsoft.azure.activedirectory.graphclient.user)user);                     }                     pagedcollection = await pagedcollection.getnextpageasync();                 } while (pagedcollection != null);             }         }         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(userlist);         }         return view(userlist);     } 

how can bind value? or maybe can write complex expression on razor view without writing on controller value?

i thought question , name sounded familiar, , that's when realised gave answer your question earlier. , think question here linked other question had.

i don't quite index controller does, not important in answering question.

i not use dictionary property extended properties. rather use collection of objects of, extendedproperty class, consists of 2 properties: name , value.

so user class have this:

public ilist<extendedproperty> extendedproperties 

in view, you'd this... note replace foreach loop for loop.

@for(int = 0; < model.count(); a++) {     var user = model[a];     ...      @if (user.extendedproperties != null             && user.extendedproperties.count() > 0) {         (int = 0; < user.extendedproperties.count(); i++)         {             @html.displayfor(m => m[a].extendedproperties[i].name)             @html.displayfor(m => m[a].extendedproperties[i].value)         }     } }
