                                </tr>
                            }

I think I am misrepresenting variable type in view, what is the solution? Thank you from now

Answer 1

Model must be known or understandable type in your view. Change it as

@model IEnumerable<FirmaCek> or @model IEnumerable<YourModelTypeInYourController> . model is sent by Index action and it should have same type in the view.

Answer 2

You're declaring your model as IEnumerable but try to use it with a List of anonymous types.

Your options are:

1. Declare it as IEnumerable of YourType and create instances of this type in your Select clause. Currently it creates an anonymous object.

Here's an example of non-anonymous creation:

                     var model = (from f in DB.FirmaCek
                                 join k in DB.KullaniciHesap
                                 on f.KullaniciID equals k.ID
                                 select new MyViewModel
                                 {
                                     ID = f.ID //add properties here                              
                                 }).OrderByDescending(f => f.KayitTarihi).ToList();

2. If you want to keep using anonymous object, use IEnumerable together with ExpandoObject like this .
