c# - Operator '==' cannot be applied to operands of type int and 'Model' -

i know error on here few times cannot find solution particular problem.

i have table foreach loop populates table data can see below, table has expand/close capability, within want display groups in there relevant sections. error operator '==' cannot applied operands of type 'int' , 'groupsection' appearing in line:

if (item.sectionid == item.groupsectionid)

i want make sure groups details can appear if groupsectionid same sectionid in particular loop

table

<table class="table table-striped">     <!-- render table headers. -->     <thead>         <tr>             <th class="col-md-1">+</th>             <th class="col-md-2">section id</th>             <th class="col-md-3">section name</th>          </tr>     </thead>     <tbody>         <!-- render details of each employee. -->         @foreach (var item in model)         {             <tr>                 <td class="col-md-1">+</td>                 <td class="col-md-2">@html.displayfor(model => item.sectionid)</td>                 <td class="col-md-3">@html.displayfor(model => item.sectionname)</td>             </tr>              if (item.sectionid == item.groupsectionid)             {             <tr>                 <td class="col-md-1" colspan="3">@html.displayfor(model => item.groupid)</td>                 <td class="col-md-2" colspan="3">@html.displayfor(model => item.groupname)</td>             </tr>             }         }      </tbody> </table> 

model

public class sectiondetail {     public int sectionid { get; set; }     public string name { get; set; }     public string description { get; set; }     public groupdetail groupsectionid { get; set; }  }  public class groupdetail {     public int groupid { get; set; }     public string groupdescription { get; set; }     public string groupname { get; set; }     public int groupsectionid { get; set; }     public string sectionname { get; set; } } 

thanks in advance , relatively new stack if need , more information etc. please let me know

you're comparing int complex type groupdetail.

if (item.sectionid == item.groupsectionid.groupsectionid) 

i think you're looking groupsectionid property inside of groupdetail class.

to prevent future confusion:

i suggest removing id suffix properties references other classes. way won't mistake int again :)
