c# - Get a value back from the MVC view outside of the model -

i have create view displays value along form. when submit have value available.

in controller have this:

public actionresult create(guid? id) {     if (id == null || id == guid.empty) return view();     viewbag.registrationverificationid = id;      var email = (from rv in _db.registrationverification                  rv.registrationverificationid == id                  select rv.email).firstordefault();     viewbag.email = email;     return view(); }  [httppost] [validateantiforgerytoken] public actionresult create(profile profilemodel) {     if (modelstate.isvalid)     {         var emailvalue = @viewbag.email;         //...     }     //...  } 

my view looks this:

@model publicationsystem.model.profile @{     viewbag.title = "create";     layout = "~/views/shared/_layout.cshtml"; }  <h2>create</h2>  @using (html.beginform())  {     @html.antiforgerytoken()      <div class="form-horizontal">         <h4>profile</h4>         <hr />         @html.validationsummary(true)          @html.hiddenfor(model => model.profileid)         <div class="form-group">             @html.label("email provided", htmlattributes: new {@class = "control-label col-md-2"})             <div class="col-md-10">                 @viewbag.email             </div>         </div>          <div class="form-group">             @html.labelfor(model => model.salutation, htmlattributes: new { @class = "control-label col-md-2" })             <div class="col-md-10">                 @html.editorfor(model => model.salutation)                 @html.validationmessagefor(model => model.salutation)             </div>         </div>         .... } 

what best way store value between response , postback?

session["email"] = email; 

this store value between response , postback. let me know if looking for.
