asp.net mvc - How do I show content and insert data form in one view in mvc -

i have contact form show contact info , users can send feedback. know must use viewmodel , use viewmodel in view. got below error:

the model item passed dictionary of type 'system.collections.generic.list`1[models.contactinfo]', dictionary requires model item of type 'finalkaminet.viewmodel.contactviewmodel'.

models:

public class contactus  {     [key]     public int contactid { get; set; }     public string fullname { get; set; }     public string companyname { get; set; }     public string email { get; set; }     public string website { get; set; }     public string contactmessage { get; set; } }  public class contactinfo {     [key]     public int contactinfoid { get; set; }      public string contacttype { get; set; }      public string contactvalue { get; set; } } 

viewmodel:

namespace finalkaminet.viewmodel {     public class contactviewmodel     {         public contactus contactus { get; set; }         public ienumerable<contactinfo> contactinfo { get; set; }     } } 

and in view:

@model finalkaminet.viewmodel.contactviewmodel      <address>         @foreach (var item in model.contactinfo)         {             <strong>@html.displayfor(modelitem => item.contacttype): </strong> <a href="mailto:html.displayfor(modelitem => item.contactvalue)">@html.displayfor(modelitem => item.contactvalue)</a><br />         }     </address>  @using (html.beginform())     {         @html.antiforgerytoken()          <div class="form-horizontal">             @html.validationsummary(true, "", new { @class = "text-danger" })             <div class="row">                 <div class="col-md-7">                     <div class="form-group">                         @html.labelfor(model => model.contactus.fullname, htmlattributes: new { @class = "control-label col-md-2" })                         <div class="col-md-10">                             @html.editorfor(model => model.contactus.fullname, new { htmlattributes = new { @class = "form-control" } })                             @html.validationmessagefor(model => model.contactus.fullname, "", new { @class = "text-danger" })                         </div>                     </div>                      <div class="form-group">                         <div class="col-md-offset-2 col-md-10 pull-left">                             <input type="submit" value="ارسال" class="btn btn-default" />                         </div>                     </div>                 </div>                 <div class="col-md-5"></div>             </div>         </div>     }
